Relief from the heat of summer and long days baking in the sun is on its way. The Northern Hemisphere's fall equinox occurs on Sept. 22 at 6:54 P.M. PDT. The harvest moon—the full moon that comes closest to the equinox—is just two nights later, on Sept. 24 at 7:53 P.M. PDT. On this date, the moon is in the constellation Pisces.
As you admire the full harvest moon, turn your gaze higher in the sky to find a circle, square and distant galaxy. The round shape close to the full moon is the Circlet of Pisces, part of the constellation of the fish. Above the Circlet and spanning a much larger swath of sky is the Great Square of Pegasus. The constellation of Pegasus rises in the east in September, with the asterism (grouping of stars) set more on end like a diamond. Imagine a large baseball diamond in the sky, with home plate nearest to the horizon. The star marking third base, Alpheratz, is actually not part of the constellation Pegasus but part of neighboring Andromeda.
While you're gazing at Alpheratz, measure 15 degrees to the left of the star to reach the Andromeda Galaxy. An easy way to do this is to stretch your arm out and create a fist, then extend and spread out your pinkie and index fingers (rock on). The distance between these fingers should mark about 15 degrees of sky and get you in the vicinity of Andromeda. You'll probably need binoculars to see it. Now that you know where to find Andromeda, try again on a moonless night and away from artificial sources of light. You may even be able to find it without optical aid.
Four Bright Planets
This month, Venus, Jupiter, Saturn and Mars are arrayed across the sky from west to southeast. On Sept. 1, Venus is quite close to the star Spica in Virgo, and the pair can be found near the horizon soon after sunset. Venus is the easiest to find because it's so much brighter than all the other points of light in the sky, but it sets shortly after the sun. A crescent moon is wide of Venus on Sept. 11 and then above Venus on Sept. 12.
On Sept. 13, the slowly growing crescent moon is close to Jupiter in the constellation Libra. The somewhat bright star closest to Jupiter is Zubenelgenubi. By Sept. 17, the moon has evolved to slightly more than half full and hop-scotched over Saturn, which is not far from the center of the galaxy. When you look toward Saturn, you are looking toward the heart of the Milky Way.
Lastly, the moon meets up with Mars on Sept. 19 in Capricornus. Mars is coming down from its "high" of opposition when it was particularly bright. The Red Planet will start September brighter than Jupiter but dim steadily until Jupiter once again surpasses it.
With all the bright planetary targets in September, there's one planet that's a fun challenge to try to find. Neptune reaches opposition on Sept. 7 at magnitude 7.8. You'll need optical aid to see it. Because it's so dim, it's difficult to distinguish from background stars. The best time to see Neptune is not necessarily opposition but whenever a brighter planet skims past it so you can focus your binoculars or telescope on the easy-to-find planet and then spot Neptune popping up in the background. You'll have to wait until December for just such a close encounter between Neptune and Mars.
Comet Giacobini-Zinner Nears Naked-Eye Visibility
You might get to see a comet without optical aid in September. Comet 21P/Giacobini-Zinner might reach naked-eye visibility around Sept. 10 in dark-sky locations. Start during the first couple days of the month by looking near the bright star Capella in Auriga, found in the northeastern sky after dark. Capella should be easy to find because it's the brightest star rising in this region of sky.
With binoculars, search for the comet by sweeping the area near Capella and looking for a hazy, diffuse area of light that stands apart from the pinpricks of stars. The comet won't stay near Capella for long, however. Each night it dives closer to the horizon, so you'll have to stay up later as September wears on to be sure the comet has risen and is visible.
By Sept. 19, the comet is positioned between the constellations of Gemini the Twins and Orion. (The comet will be a wide left of Orion's reddish shoulder star Betelgeuse.) By the end of September, the comet is nearing Sirius in the constellation Canis Major. Giacobini-Zinner will complete a large loop around the Greater Dog over the coming months as it slows its progress through the sky and dims until it's out of the reach of most backyard telescopes.

The future of the auto industry is increasingly likely to be electric—although you wouldn't necessarily know that from sales numbers. Just under 200,000 plug-in cars were sold in the United States last year (out of a new-car market of 17.25 million). In California, cars with plugs made up 4.6 percent of the new-car market in 2017, while nationwide the number increased only slightly, to 1.16 percent of total auto sales. But 2018 is shaping up to be better, with 36 percent higher EV sales in the first four months than in the same period the previous year.
Elsewhere, meanwhile, EV sales are booming. Last year China's EV sales were more than three times those of the United States, accounting for nearly half of all plug-in vehicles purchased worldwide. In tiny Norway, thanks to great incentives, more than half of all new-car registrations in 2017 were either hybrid or battery electric.
The United States has a chance to catch up. Amid a welcome proliferation of EV models, the general trend is that most new cars will be offered with a plug-in variant. The consumer today has a lot of good EV choices that are much cleaner than conventional vehicles, even factoring in emissions from the electricity used to charge them. Both range and performance are improving as prices come down. If electric cars can travel 300 miles on a charge—as do some versions of the Tesla Model S and upcoming cars from Volkswagen and Porsche—then the old shibboleth of range anxiety may no longer apply.
Here are six noteworthy 2018 models, both full battery electric and plug-in hybrid. It's important to point out that all these cars come with federal incentives of up to $7,500. Many states offer further financial subsidies as well as perks such as priority parking and single-passenger privileges in HOV lanes. All prices stated below are base prices, without federal and state incentives or destination charges (the cost of shipping the car from manufacturer to dealer).
Toyota Prius Prime
The Prime is a big step up from the first Toyota Prius plug-in hybrid. Based on this model's 25 miles of battery-only range, it will save the average commuter $561 a year in fueling costs, compared with driving the average car. With savings like that, the quirky styling will grow on you. Base price: $27,300. The $33,300 advanced package includes a tablet-like screen and a full range of infotainment and safety technology.
Kia Niro Plug-in-Hybrid
The standard Niro arrived last year, but it's the plug-in hybrid version that has my attention—not least because it offers 26 miles of electric travel (and up to 560 miles of total range) via its 8.9-kilowatt-hour battery pack. The subcompact SUV pairs its electric motor with a 1.6-liter four-cylinder engine. There's a really useful cargo capacity of up to 54 cubic feet, and five adults can ride comfortably. Base price: $27,900.
With 238 miles on a charge of its 60-kilowatt-hour lithium-ion battery, the 200-horsepower Bolt pioneered the affordable long-distance EV. "The Bolt is my third electric vehicle, but the first one that allows me to completely forget about range," a California Bolt driver told me. (A downside of the big battery is a long full-charge time—9.5 hours at 240 volts/32 amps—although drivers rarely start charging on "empty.") The Bolt is futuristic inside and out, handles well, and is very fast off the mark—zero to 60 in less than seven seconds. It has essentially the same value proposition as the Tesla Model 3 but without the long wait. Base price: $37,495.
The Chrysler Pacifica plug-in hybrid minivan is outstanding in its field—but it's the only one in that field. The minivan remains more practical than most SUVs for transporting families and cargo, but it suffers from an unfortunate image problem in a market that celebrates sexier formats. Chrysler is to be commended for taking a leap of faith. The front-drive Pacifica will accommodate seven passengers and has 32 cubic feet of cargo room. The third row of seats can be fully stored in the floor with the press of a button. The Pacifica is rated at the equivalent of 84 miles per gallon in combined driving, or 32 mpg with just its 3.6-liter Atkinson-cycle V6. But it has more than 30 miles of electric-only range, and its 16-kilowatt-hour lithium-ion battery charges in just two hours on 240-volt power. Base price: $39,995.
Tesla Model 3
If you can get your hands on one, the Tesla Model 3 EV sedan is worth the effort. With similar performance to the vaunted Model S in a more compact package, it's a technological marvel and (compared with other Teslas) something of a bargain—which is why more than 400,000 people are on the list to buy one. Tesla's production line is having teething problems; if you sign up now, the wait will be up to 12 months. The Model 3 is hugely fun to drive and boasts a very futuristic dashboard. Forget instruments—all the functions are on a touch screen that can be updated remotely. Most buyers will opt for the long-range battery, which gives 310 miles on a charge. (In fact, that's the only option in early production.) Base price: $35,000; with long-range battery, $49,000. (Disclosure: Tesla CEO Elon Musk is a major donor to the Sierra Club.)

How We Reviewed Portable Solar Generators
A good portable generator will offer you backup power in a convenient and reliable way. We have reviewed some of the top models on the market today, and arrived at a few that we think stand out from the rest.
To rank the best solar generators, we considered the following criteria:
- Size and weight. Smaller, more lightweight units offer much greater ease of use. We sought portable solar generators that aren't too challenging to lug around your home, or take with you when you go camping.
- Battery storage capacity. While your generator absorbs light through a solar panel, that energy is ultimately stored in a battery. The battery storage capacity, measured in watt-hours (Wh) determines how long you can use the generator before it requires a recharge.
- Inverter rating. Basically, inverter rating refers to the total number of watts that the solar generator can extract at any given time. Inverter rating, along with battery capacity, determine the wattage and power output of your generator.
- Expandability. Some generators come with a predetermined number of solar panels, while some allow you to add more solar panels as needed. This is an important feature to consider when looking for generators.
- Price point. Naturally, when looking for a new solar generator, staying on budget is always going to be a factor. We chose generators that are competitively priced.
The Best Portable Solar Generators
With these ranking factors in mind, here are our picks for the best portable solar generators available in 2021.
Goal Zero's line of Yeti portable power stations are well-suited for a wide range of off-grid uses, including emergency power, camping trips, and more.

Why buy: The Goal Zero Yeti 1500X includes a 2000W AC (3500W Surge) inverter giving you the equivalent of a wall outlet power supply on-the-go. It also has seven different port options and a top-of-the-line app that makes it easy to monitor and manage your solar powered generator, no matter where you are.
For a high-capacity power station, check out the Bluetti EB150 from MAXOAK. Though it's not the most affordable option, you'll get a lot of features and utility for your investment. It includes a lithium ion battery capacity of 1500 Wh. When connected to three 150W solar panels, it can be recharged in about 3.5 to 4 hours.
Why buy: For a portable solar generator designed to power most household appliances under 1000W, the high-powered Bluetti EB150 is a great choice. MAXOAK also backs their product with a 24-month replacement or maintenance warranty.
EcoFlow boasts an impressive catalog of portable power stations, as well as reliable solar panels. We like the EcoFlow RIVER Pro power station because its technology enables incredibly fast recharging; you can connect it to two 110W solar panels to recharge in as little as 4.5 hours.
Why buy: The EcoFlow RIVER Pro includes a wide range of best-in-class technologies. Offering 720 Wh of power with three pure sine wave AC outlets, and weighing only 15.9 pounds, these units are well-suited for camping and hiking, as well as use around the house. You can also add an additional EcoFlow battery pack to upgrade the power of your generator as needed.
Renogy produces several different power stations and chargers, but we especially like the PHOENIX 300, a solar power solution that's extremely lightweight and compact. It comes with an easy-grip handle and only weighs 6.4 pounds, making it one of the most portable solar generators around while still offering up to 200W of AC power for off the grid activities.
Why buy: The PHOENIX 300 can provide 337 watt-hours for up to 8 hours of AC continuous power without the noise or fumes associated with gas generators. It includes a number of the most common charging ports like two AC adaptors, a USB-C, USB-A, USB, and a D-Tap port for photography equipment.
Suaoki is a company that's known for simple, functional, reliable technology. Their S370 portable solar generator isn't necessarily flashy, but it's an extremely lightweight option, perfect for camping, hiking, and other outdoor adventures. It includes 14 outlet ports and a pure sine wave inverter, making it a versatile power option.
Why buy: This is one of our top picks for camping and hiking, though it may also serve your needs as a backup power station for small appliances and electronics. A lithium-ion battery gives this generator an incredible capacity battery life, particularly in relation to its compact size.
Jackery's portable power stations are ideally suited for camping and hiking. The Explorer 300 offers great portability and fast rechargeable power at an affordable price. It includes two AC outputs, a USB-C, USB-A, USB ports, and a 12-volt car port.
Why buy: The Explorer 300 generator is a good option for those who are new to solar power, thanks to its low price and easy-to-use controls. Jackery offers a number of portable solar panel options, and the power station's MPPT technology means that it can be recharged from the sun in just 5.5 hours.
There are plenty of reasons to consider the Westinghouse iGen200s portable generator. This is one of the more affordable options on the market today, which makes it a good entry-level solar power solution. The unit offers four charging options. You can recharge with solar panels, with the power from your vehicle, with a household power outlet, or with a separate generator.
Why buy: For a simple and inexpensive solar power generator, Westinghouse makes an outstanding product. You can charge up to nine devices at a time; and, depending on how you use it, you can potentially get more than 40 hours out of your generator.
What Types of Batteries Do Solar Generators Use?
It's important to note that solar power generators may employ different kinds of batteries. The most common option is the lithium-ion battery. These tend to be more expensive than lead-acid batteries, at least on the front end. With that said, a lithium-ion battery will prove more durable, which usually makes it the smarter investment in the long run. Solar generators include charge controllers, which regulate the volts of energy coming from the solar panels to the battery to make sure the battery isn't overcharged and damaged.
The energy stored in the battery is converted from DC power into AC power using an inverter or adapter.
What Can You Power With a Portable Solar Generator?
There are different types of solar generators. A backup generator is primarily used to power your home, should your electricity go out. In this article, we focused on portable generators, which are mostly used for hiking and camping. With that said, a portable generator can also be really useful during power outages, potentially keeping your lights, electronic devices, and small devices or appliances on for several hours. Depending on the watts of power your solar system generator kit can support, you can use it to power things like phones, tablets, laptops, TVs, coffee makers, a mini-fridge, certain medical devices, and most anything you would plug into a car charger.
Some of the generators we've listed here can be charged by solar energy or via other sources, including vehicles and power outlets. These different charging solutions make a generator more versatile, though of course, solar energy is what you'll want to use if staying away from fossil fuels is your goal.
What are the Benefits of a Portable Solar Generator?
There are a number of reasons why you might consider a portable solar generator:
- These units are ideally suited for camping and hiking. The ones on our list range in weight from under 10 pounds to over 50, but they are all fairly easy to cart around as needed, or to keep in your camper or RV.
- Though they are not primarily intended to be emergency backup generators, they can certainly be used in that capacity. In particular, they can provide emergency power to important medical devices as well as phones and computers.
- Unlike gas generators, portable solar generators offer power without making a lot of noise or creating a lot of fumes. This makes them much more appealing for campsites.
- Portable solar generators are better for the environment, since they don't rely on gas or diesel fuel to run.
- Using a solar generator is ultimately more cost-effective as you will never need to purchase fuel to recharge it.
Solar Power Can Take You Further
Solar power is one of the best options for dependable, renewable energy. Not only can it help power your house, but you can use these portable generators to carry that power with you, wherever you may go.
There are clearly lots of options on the market today. We hope our guide is helpful to you as you assess our own backup power needs, and as you determine which portable solar generator will give you the greatest value. Note that you can find many of these solar power options through third-party retailers like Amazon. Do your due diligence as you seek the perfect, portable solar solution for you and your family.

I am sitting near the top of the eastern ear, or rather the eastern earlobe, of Bears Ears, the redock buttes that give our most controversial national monument its name. From up here I can look back on my starting point, the meadow far below and two miles north where a big white tent marks the social center for the reunion of five Native American tribes during the fourth annual Bears Ears Summer Gathering. Hundreds of Indigenous people, environmental organizers, and members of the media like me make up the first meeting of this sort since President Trump and Interior Secretary Ryan Zinke announced, last December, that they were going to reduce Bears Ears by 85 percent.
Although this July celebration is taking place legally on public land—land that is still, despite the reduction of a million acres around it, a national monument—the event hasn't exactly been greeted with open arms by the local white ranchers. In fact, as one young Navajo man put it earlier, it feels a little like we are under siege.
"You look like an environmentalist. Get back in your truck!" This was the greeting one of my fellow celebrants got from one area resident when he stopped to check how deep his back tire had sunk in the muck. Other cars had been tailgated as they made the drive to the celebration. Someone moved the signs for the event so that many of the attendees—and the porta-potties—ended up in the wrong place. The ribbon that marked the pull-off for the road to the gathering was stolen. The Native American organizers responded by placing volunteers on the roads at each turn to make sure guests weren't being misled. Not long ago a private plane buzzed low over our campsite.
"You can tell how special a place is by how many people try to keep you away from it," Navajo elder Jonah Yellowman told me soon after I arrived. I saw what he meant during my hike up here. After lunch these matching buttes looked like an open invitation, and since we were on monument land, I assumed I could walk directly toward them. But barbed-wire fences and grazing cows cut off most of the access, siphoning me to the single point where I could open a gate, scramble up a gully to the public road, and finally get to the base of the eastern butte. Then I climbed to the spot where I sit now. But even then the fence followed me. In a strange marriage of redrock and barbed wire, of public and private, the fence continues right up to where the rock turns vertical, a place no cow could climb.
It feels odd to be fenced in on land that even Donald Trump and Ryan Zinke admit is still a national monument. Public lands are said to belong to all of us, but hiking here, I have experienced the anxiety of the intruder. Looking out at hundreds of miles of land and a half-full moon through an opening in a fence, I am in a fought-over spot in this fought-over landscape in our fought-over country. Maybe this place embodies our world right now. All the battles between red and blue, future and past, are being fought right here, at this point where redrock meets barbed wire and where Native peoples celebrate while white ranchers resentfully prowl the outskirts.
On the hike back, I think of a statistic I recently read: Over a third of the land in the contiguous United States is pasture land, with a quarter of that being land leased by the government, and that almost all of that land serves the cow. I am very careful to reattach the wire loop that secures the gate that leads back to the meadow. Just last week saw the beginning of the trial of environmental activist Rose Chilcoat and her husband, Mark Franklin, in what some of us are choosing to call Gate-gate. Chilcoat was a former director of the environmental group the Great Old Broads for Wilderness, and she and her husband are accused of closing a gate on a rancher's property that denied his cows access to a watering hole. This is just the sort of battle that makes San Juan County seem both uniquely quirky and a microcosm for the rest of the country. Here the wars never stop raging between environmentalists and those who resent federal intrusion, and between Native people and locals.
But who are the real locals? Over 50 percent of the residents of San Juan County are Indigenous people and, if the recent primary election is any indicator, two out of the three San Juan County commissioner seats could go to Navajos. Meanwhile "local" Zane Odell, one of the most vociferous opponents of Bears Ears, is actually a Colorado resident. As for the land I am now walking through, it was once the childhood romping grounds of the great Navajo chief Manuelito. He used Bears Ears in the 1860s to hide out from the U.S. Army but then gave himself up to join his people and care for the children and elderly during the Long Walk, the forced eviction and march of Navajos to Fort Sumner in New Mexico. And the Navajos are not alone in seeing this land as a homeland. The Ute traditional territory encompasses Bears Ears, and the Ancestral Puebloan people, including the Hopis and Zunis, don't have to look hard to see clear evidence that this was once their home. That evidence still inhabits the landscape in the form of the plentiful ancient dwellings and artifacts.
"Chief Manuelito wanted peace, but he was ready to fight," Kenneth Maryboy, a Navajo member who is the current Democratic nominee for one of the three county commissioner seats, is now telling a few dozen of us who are gathered under the huge tent. "Manuelito said, 'There is a day when my enemy is going to kill me. But I'm not going to go quietly. Trees and rocks will be ripped up around me. I will take many with me before I go.'"
Perhaps Maryboy is in a fighting mood, having just won the primary for a commissioner seat over Rebecca Benally, who stood next to Trump when he announced the Bears Ears reduction in Salt Lake City last February.
Maryboy's words are inspiring, but they are one of the few aggressive notes during the weekend gathering. The theme of this year's celebration is "Bears Ears Is Healing" and that seems to be happening. A couple hundred of us are camping here, and it's the most social camping I've ever done. Each morning a color guard made up of veterans raises the U.S. flag. We then greet the sunset near the Bear Totem Pole that was carved and brought here as a gift of goodwill and support from the Lummi Nation of Washington State. Then everyone goes in search of coffee in the kitchen tent. All three days, the weather is perfect, and violet morning light plays off of Bears Ears, with its rich, almost edible, red-orange colors shining out from below the green of ponderosa and piñon pines. Mountain bluebirds and cliff swallows shoot from tree to tree in the meadow below the ears.
William Greyeyes, the board chairman of the Utah Diné Bikéyah and one of the original leaders in the struggle to establish Bears Ears, tells me that the lack of local hospitality is nothing new.
"This has happened in past years too," he says. "We just ignored them and re-established our path and kept going forward. That's the only way to do it. These are public lands, federal public lands. It's open to everybody. And they are welcome to put forward a proposal to the United States government. Just as we did."
And so the weekend continues peacefully, including prayer, medicinal plant walks, programs for kids, the dedication of the bear totem, a 5K run, and more mutton than I have ever eaten in my life. By the end of the second day, the anger from the locals has died down and the mood of the gathering is buoyant. Speakers remind us of what was gained, what still is, and what might be again. Of possibilities, not loss.
On Saturday night, the final night of the gathering, I decide to pack it in early after a delicious dinner of bison and beans. Too tired for any more interviews, I stumble back to my tent. But then, lying there, I hear the music. And then a voice over the microphone. The voice belongs to Regina Lopez-Whiteskunk, the former councilwoman for the Ute Mountain Ute on the Bears Ears Inter-Tribal Coalition. Lopez-Whiteskunk was the first person to tell me the Bears Ears story, back in January, and soon I am climbing out of my sleeping bag and heading back to the big white tent. Lopez-Whiteskunk, dressed in traditional Ute clothing, is dancing to music played by her father and other family members. Her granddaughters, also in traditional dress, sit on the stage and whisper to each other. I join along with everyone else in the final dance, a great snaking circle that turns inward on itself and tightens until we are one great, knotted ball. The dance ends in laughter and applause.
After the dancing, Lopez-Whiteskunk talks to the crowd. Her theme is how to deal with Trump's assault on Bears Ears, and the aggressive opposition the tribes face.
"This is not new for us," she says calmly. "We are used to this. We will adapt."
She reminds us of what has already been accomplished.
"We did it. Yes, they are trying to take it away. But we did it. Remember that."
I like her calm. It soothes. But I also remember Kenneth Maryboy's sterner message.
Taken together, they sound something like this:
We talk, we plan, we teach, we learn, we celebrate, we dance. We try to heal.
But, if necessary, we fight. Like Manuelito, we won't go quietly.
We will fight, and trees and rocks will be ripped up around us . . .

ANABEL'S GROCERY IS A STUDENT-RUN INITIATIVE DESIGNED TO COMBAT FOOD INSECURITY ON THE CORNELL CAMPUS, PROVIDING LOW-COST GROCERIES TO STUDENTS.CORNELL UNIVERSITY
Last year, Cornell launched Anabel's Grocery, a student-run food supply providing low-cost access to local, organic, and culturally inclusive foods. It also broke ground on the Sustainable Landscapes Trail, designed to highlight 14 campus spots that showcase Cornell's commitment to natural lands management (think rainwater capture stations, pollinator plants, and permaculture plots). Since 2008, this Ivy has reduced campus emissions by 36 percent and cooling energy by 86 percent, largely through proprietary innovations such as Lake Source Cooling—running a pump from one of upstate New York's nearby deep lakes to pipe cold water through campus. The Touchdowns are now experimenting with Earth Source Heat, a new system that involves drilling into the earth's upper crust and piping thermal heat through the often-chilly campus.

As a result, the school has already reinsulated 16 miles' worth of campus steam and condensate pipes, thus reducing at least 54 metric tons of annual greenhouse gas emissions. The Ducks' new-and-improved climate plan is also funding environmental economists' research into internal carbon taxes that U of O, and perhaps eventually other institutions, could implement. The university is currently installing a shipping container outfitted with LED lights wherein students can experiment with the latest in indoor agriculture and recently received a grant to integrate sustainability courses with the work of area municipalities and nonprofits—meaning students will be working to solve real-world energy and transportation issues. Through "rEV Up Eugene," the University of Oregon hosts free community workshops about electric vehicles.

"There's snow up here, I promise," I assure my son Jonah, as we grunt up a south-facing mountainside in Glacier National Park in July. A mountain goat cocks its head as if to say, "What kind of crazy people hike up bare mountains in ski boots?" He's not the only one to wonder what in the name of Bode Miller we're doing up here with ski gear.
Our day began at Logan Pass, the high point of the park's famed Going to the Sun Road, where plows work for months to carve a byway through walls of deep snow. By July that snow has melted into a predictable patchwork, and even on the highest summits the south slopes are bare. As Jonah and I set out from the parking area on skis, tourists raise their phones to take pictures of the spectacle while children from warmer climes throw snowballs.
An hour later the crowds are far behind us as our snow patches run out and we arrive at the foot of a south-facing mountainside and remove our skis. A bare-chested man with a vigorous hiking stride looks up the daunting pitch above us. Our plan to ascend it, he opines, "sounds like a lot of work."
Despite my confident response to Mr. Bare Chest, I'm secretly worried. There's a fine line between passing on your love of the mountains to your kids and alienating them by pushing them too far. Jonah is 15 and a high school athlete. He can handle this. I hope.
But so far he's a bit morose in that dispiriting way particular to teenagers, so I offer him the option of turning around and doing something easier in the tourist zone. To my pleasant surprise he opts for the bigger, much more challenging adventure. So we lash our skis to our packs, find one of Glacier's many informal climber's trails, and begin our climb into the world of mountain goats and summer snow.
Hours later we gain a knife ridge at 8,000 feet. Sharp peaks laced with waterfalls spear the sky in every direction. The northern side of the mountain drops steeply into a sheltered alpine bowl harboring a thick snowpack. "Told ya we'd get to snow!" I exclaim to Jonah—who is focused on trying to communicate telepathically with the mountain goats lounging on the snowfield.
Below us stretches a beautiful, wild ski run of 1,000 vertical feet. Its high alpine fastness makes it virtually unreachable in winter, but its shady northern aspect in a sheltered cirque preserves it for a fine run in July. We strap on helmets and click into our skis. The slope is steep enough that only the beginning is visible before it plummets away out of sight.
I tell Jonah to follow my line closely, as there are rock bands, small crevasses and other hazards to avoid. After I take a couple turns to test the snow, which has an amenable surface perfectly softened by the day's sun, I tell him to drop in behind me. He's on my old skis, which are a bit long, but he carves his way down the mountainside like he's been doing it all his life. Which is probably because he has.
His father is what you could call a skiing addict. Nothing mainlines joy for me like the wild poetry of gliding down snowy mountainsides, and I've tried to instill proper values in my two sons. If it snows more than six inches, abandoning school for a ski day is optional; more than 10 inches and it's mandatory.
But it wasn't until well into adulthood that I realized you needn't put skis away when winter ends. It started with May. I figured out that even by that late date, snow sticks to high mountains and provides stable glissè opportunities on steep slopes that would be too perilous in avalanche-prone mid-winter. From there, it was only a matter of time until I found myself skiing in the first days of June, when most people are gardening. But making the jump to true summer skiing took a bit longer because, well, snow is harder to find in summer.
Then a friend who's a backcountry skiing guide showed me the hidden side of Glacier's Logan Pass and began inviting me on adventures into remote places that involved fording creeks with skis on our backs and other alpine shenanigans. As you might imagine, we were always the only people back there. Which was all I needed. Wilderness exploration with glorious ski runs far from madding crowds? Sold.
Soon I was exploring the Northern Rockies' other hotbed of summer skiing, the Beartooth Mountains on the Wyoming-Montana border. I heard stories of people doing the same in the Cascades, Rocky Mountain National Park, and California's Mount Shasta. Many of them are part of an ever-growing tribe of year-round skiers—calendar-obsessed souls who've vowed to ski at least once in every month of the year. I now have multiple friends who've been doing so for over 10 years. From them I've learned of the ever-more esoteric locales they use for August and September runs, shadowy creases and perennial snowfields hanging in alpine basins. I'm not quite there yet—I'm loathe to let things like calendars and clocks dictate my agenda. But I no longer think they're crazy. Summer skiing, it seems now, is little more than a day hike in the mountains with a more elegant route back down.
Jonah is all smiles as we fill our water bladders from a snowmelt creek at the bottom of our first run. From there we have another big climb up a steep slope of loose rock. Again I'm worried it might break his effervescent spirit. But letting him choose our climbing route and lead the way imbues him with newfound energy. Although we've been clambering around for at least six hours, he moves up the rough terrain with enthusiasm and we chatter cheerfully without pause.
It's a perfect example of what happens when you bring kids into the wilderness: Removed from civilization's coddling hands, young people perk up, sensing they have only themselves and their companions to rely on. Give them responsibility and that sense of wild agency crystalizes and before you know it, you've got an adventurer on your hands. At least that's what it felt like watching Jonah scramble up that mountainside as if the mountain goats had passed on to him some secret caprine wisdom.
We high-five at the top where the world opens up again. Logan Pass sprawls below us, tourists marching in a line like ants up the snow-covered boardwalk. There's another long ski run at our feet and more tourists will stop and point and take pictures as we carve our way down it, marveling at the crazy people skiing in mid-July. I marvel, too, as I watch Jonah gleefully and even expertly soar down the mountain below me. It's then that I realize that I've been wrong to think that nothing brings me joy like skiing. I now know that nothing brings me joy like watching my son ski a wild mountainside—and then plunging down behind him.

Call it the "People's Climate March, Part III." On Saturday, Sept. 8, thousands of people are expected to converge on the streets of San Francisco to demand that government leaders commit to ending all new fossil fuel projects and accelerating the move toward renewable energy. The march is part of a global campaign calling for environmental justice and a "just transition" to renewable energy that protects workers and frontline communities. Satellite events will happen across the U.S. and around the world, including Indonesia, Turkey, Nigeria and the United Kingdom, among other places.
"We're making sure that politicians see what diverse climate leadership must look like, to successfully serve the entire population of people who are actually affected by climate change," Antonio Díaz, organizational director for People Organizing to Demand Environmental and Economic Justice (PODER), said at an Aug. 8 press conference announcing the upcoming march. Representatives from labor unions, environmental justice groups, faith alliances, and immigrant rights organizations gathered in front of San Francisco's Ferry Building to deliver an unequivocal message: Climate justice cannot wait for a new administration in Washington, DC. Climate-related disasters are becoming the new normal, they said, and political solutions for adapting to them must include the protecting the communities most affected by disasters.
In comparison to previous Peoples Climate Marches in 2014 and 2017, a heightened sense of urgency surrounds the upcoming mobilization. The first People's Climate March took place in New York City in September 2014, on the eve of the United Nations General Assembly meetings, and marked something of a coming out party for the global climate justice movement: There were demonstrations in 162 countries, and the presence of some 400,000 people on the streets of Manhattan blew away organizers' expectations. The following year was full of heady expectations. Pope Francis published his landmark encyclical on the moral obligation of protecting communities from climate change, "Laudato Si" (Latin for "Praised Be," from a prayer by the pope's namesake, the patron saint of ecology). In December 2015, leaders from around the world signed the Paris climate agreement, a historic pledge to coordinate efforts to reduce greenhouse gas emissions. "It was an exciting time for all of us," said Nana Firman, director of Muslim Outreach at GreenFaith, which has participated in all three marches, "to see leaders and communities around the world put their voices together [to say] that this is not just a political issue, but a moral and ethical issue."
By 2017, the political landscape had shifted—and not for the best. Newly inaugurated President Trump had signed an executive order rescinding the moratorium on coal mining on federal lands, and then-Environmental Protection Agency administrator Scott Pruitt was busy systematically trying to dismantle environmental protections at an alarming rate. On Trump's 100th day in office, tens of thousands of demonstrators united in Washington, DC for the second Peoples Climate March, to send a message to the White House and congressional leaders that any attempts to retreat from action on climate would meet stiff resistance.
Next month's march will take place under even more difficult circumstances. Even as global climate change is becoming impossible to ignore, Trump administration officials continue to deny basic climate science while enacting policies that are blatantly influenced by fossil fuel interests. The situation is grim for environmental protection: the White House has announced its intention to abandon the Paris climate agreement, the acting EPA administrator is a former coal industry lobbyist, and the Interior Secretary has opened millions of of acres of public land for oil and gas extraction.
The upcoming march is a direct response to California Gov. Jerry Brown's highly anticipated Global Climate Action Summit, which begins in San Francisco on Sept. 12 and will draw government officials, civil society representatives, and business executives from around the world. (Former New York City Mayor Michael Bloomberg, a major donor to the Sierra Club, is one of the co-chairs of the summit.) The march is part hello-welcome and part political challenge as protest organizers call on Gove Brown to prohibit any new oil and gas extraction and fossil fuel infrastructure in California. Organizers are asking the outgoing governor to "set a global precedent" by phasing out oil and gas production and moving toward "a fair and equitable transition that protects workers [and] communities." Many of the environmental justice groups organizing the march have long been opposed to other Brown environmental policies such as California's greenhouse gas cap-and-trade program, which they say allows industry handouts on emissions permits while harming communities of color.
"Governor Brown's summit is a continuation of the market-based schemes that actually result in increased local pollution and emissions," said Gladys Limon, executive director of California Environmental Justice Alliance (CEJA). "While they purport to address the collective problems of climate change and reduce emissions in the aggregate, they continue the unconscionable practice of using [frontline communities] as sacrifices."
A key demand of the September march is for governments to create climate resilience strategies that protect frontline communities located in areas that can be disproportionately affected by climate change and yet are often without resources to rebuild after unprecedented natural disasters. Annie Dobbs-Kramer, organizer for voter engagement at North Bay Organizing Project, was shocked by the connection between limited disaster relief and communities of color, low income, and immigrant families during the Northern California wildfires of 2017. "It was really apparent how climate change-related disasters create climate refugees," Dobbs-Kramer said. "The same people who get systematically exploited on a daily basis [become] even more so during climate disasters. It was appalling to see that." Families with English as a second language had little way of knowing where to obtain basic necessities, or how to find evacuee centers; low income residents were dependent on dwindling financial services, often from nonprofit organizations instead of municipal disaster funds. "[Climate change] is crystallizing the separation between the haves and have-nots," Dobbs-Kramer said.
March organizers argue that climate policies that make concessions to fossil fuel industries in the interest of long-term gains are ultimately ineffective, if the communities who are most exposed to climate change suffer in the short-term. "We will be … in solidarity with communities across the state and around the world," said Limon of CEJA, "to challenge and expose the flawed solutions that elected officials and industry have developed. Instead we will raise our voices for community-led solutions."
The organizers of the march have a blunt message for elected officials: "See you in the streets."

When was the last time you looked around your kitchen or bathroom for chemicals that are toxic to your health? In many households, those chemicals don't just come in the form of liquid products like pesticides or bleach. They often can be found in the most common items lying around, like frying pans used to cook up a morning egg, or in that popcorn bag heating up in the microwave. That's because a class of highly toxic, long-lasting chemicals called perfluoroalkyl substances (PFAS) has become ubiquitous in American products.
PFAS have been used in American households since the 1950s, when it was first marketed in Teflon cookware by DuPont. Today, PFAS are added not just to nonstick pans, but also water-resistant clothing, grease-repelling fast food wrappers, stain-proof carpets, and other products. Its unusual resistance to degradation is what makes PFAS so damaging to human health and the environment: decades of study has shown that accumulation of PFAS in the bloodstream can cause various cancers and birth defects. Yet the Trump administration is reluctant to make the dangers of PFAS, and its common use, widely known to the American public.
In January, the Trump administration tried to suppress a report about PFAS that was conducted by the Agency for Toxic Substances and Disease Registry (a division of the EPA)—the latest instance of the administration's predilection for scientific censorship. An internal aid stated that public knowledge of PFAS toxicity and its use in consumer goods would create "a public relations disaster." Six months later in June, the ATSDR released the report, which conclusively links PFAS to a host of harmful side effects and recommends lowering the EPA's current non-enforceable risk level to 12 parts per trillion, down from 70 ppt (about the size of a drop of water in an Olympic pool).
The report links PFAS exposure to liver toxicity, immune disruption, and developmental problems. In court cases against chemical manufacturers, plaintiffs and medical studies have also linked PFAS in drinking water to kidney cancer, testicular cancer, thyroid disease, ulcerative colitis, pancreatic cancer, and birth defects. "It's an unusual list of chemical effects," says Sonya Lunder, Senior Toxics Policy Advisor at Sierra Club. "It's hard to tie that all together—it's affecting multiple parts of the body in different ways."
Exposure to PFAS isn't only limited to household products, and its presence in drinking water has led to intense litigation. Thousands of people who live near manufacturing plants owned by companies such as 3M and DuPont have reported water toxicity levels exponentially higher than the EPA limit, often sourced from storm runoff that seeps from chemical plants into the ground—or, from illegal dumping directly into rivers and creeks. In the absence of federal regulation, numerous states have sued chemical manufacturers that produce PFAS for damages to public health and the environment. Minnesota filed a lawsuit in January against Wolverine World Wide, to recoup the cost of PFAS cleanups and municipal water installations for contaminated wells. In February, North Carolina sued Chemours, a spinoff of DuPont, for failing to take action after rainwater runoff mixed with GenX, Chemours' special group of PFAS used in Gore Tex clothing, and contaminated the Cape Fear River. In that same month, Ohio sued DuPont and Chemours for contaminating waterways with PFAS used to make Teflon, and for withholding knowledge of PFAS' dangerous side effects to the public.
These lawsuits are not without precedent, and some have already been successful. In 2017, DuPont settled a class action lawsuit in West Virginia for $671 million dollars, in reparations for 3,550 personal injury cases in the state over contaminated water and cancerous side effects. In February of this year, 3M settled a lawsuit with the state of Minnesota for $850 million, after eight years of litigation over PFAS that had leached into public drinking water as a result of making Scotchguard.
Despite these cases and the evidence they present, PFAS remains unregulated, and the path to controlling its production faces a troubling obstacle. The U.S. Department of Defense uses PFAS as a critical component in firefighting foam at military bases throughout the country, where it's used to put out jet fuel explosions and in demonstrations for Navy training exercises. Compounding this, the cost of waterway cleanups and carbon filtration in contaminated cities would net an estimated $2 billion—all on the Department of Defense's budget. To protect its relationship as a supplier for the DoD (and defend against the massive litigation in West Virginia), in 2001 the chemical industry created theFire Fighting Foam Coalition, a lobbying alliance of chemical manufacturers and distributors. The FFFC has spent years making persuasive presentations to the EPA and the military, arguing that PFAS are not only nonhazardous, but necessary for domestic security.
Today, 99% of Americans are predicted to have PFAS in their bloodstream, where it is passed on to newborn babies. The Environmental Working Group estimates that more than 1,500 drinking water systems across the country, serving at least 110 million people, are contaminated with PFAS.
The solution to PFAS regulation should not hinge on the outcome of case-by-case litigation. As high as DuPont's $671 million settlement with West Virginia sounds, it was a drop in the bucket compared to the company's $79.5 billion revenue for the year of 2017. Regulating PFAS by individual chemical, and not class, is also untenable: GenX was created by DuPont directly in response to the EPA banning production of PFOA, the main chemical in Teflon; the new class is just different enough from PFOA to escape regulation, but with all the same side effects. "PFAS has to be regulated as a group; we can't just ban one or two chemicals, and watch the industry shift to another similar one," says Lunder. "We need to stop all unnecessary uses of these chemicals in new products. It's not for [city and state] water districts to go bankrupt cleaning up the water[of contaminated regions]."
One step to fighting PFAS production is to raise awareness in communities where chemical manufacturing plants are, and to ensure that the public has legal representation to fight back— and demand that elected officials prevent chemical companies from producing it in their state. Sierra Club is working with environmental lawyers and county officials in North Carolina, Colorado, and other states where PFAS are produced, with the aim of ensuring that every affected citizen is aware of and armed against the toxic secret living in their environment.
"We are taking the veil of secrecy off this," says Lunder. "Facilities need to be reporting their PFAS use and emissions into the environment. Pollution is profitable, but [with the] price tag of these cleanups, it's not viable."

August is the time to sit back, relax and enjoy the free show overhead.
The Perseid meteor shower is one of the most prolific annual meteor showers and the only one that occurs in the summer. The Perseids can produce up to 100 meteors an hour at their peak, which is around Aug. 11/12. Skies will be nice and dark thanks to a new moon on Aug. 11, which will make it easier to see even the faintest streaks. Find a location away from trees, buildings and light pollution, and look up to catch the fast-moving meteors as they burn up upon contact with our atmosphere. These meteors come from the Great Comet of 1862, Comet 109P/Swift-Tuttle.
Parade of Planets
A sky full of planets continues to entertain us in August. The brightest and closest planet, Venus, drops low in the west and sets not long after sunset. Jupiter trails behind Venus in the southwest, setting four hours after sunset at the beginning of the month and disappearing more quickly by the end. Venus mingles with the moon on Aug. 13 and 14, and Jupiter gets a visit from the moon on Aug. 16 and 17.
Saturn is low in the south, floating before the stars of the Milky Way. The Ringed Planet lies in Sagittarius, close to some stunning star clusters and nebulae. The moon will come into the picture on Aug. 20, brightening the Milky Way environs, so try a couple days before or after this date if you want to hunt down deep-sky delights near Saturn.
Mars reached opposition in late July, one of its closest approaches to Earth in a number of years. The bright, reddish-orange color of the planet should still be unmistakable in the south-southeast. A planet-wide dust storm has been extinguishing our view of features of the Red Planet, but during calmer weather it's possible to spy white wisps of polar caps and clouds on the Martian planet through backyard telescopes. The moon passes Mars on Aug. 22 and 23, and it hits full phase on Aug. 26 at 4:56 a.m. PDT. August's full moon is sometimes called the Sturgeon Moon.
Double Transit on Jupiter
Get out your telescope or binoculars on Aug. 23 to catch the double shadow transit on Jupiter. The timing of the event will depend on your location, so start looking after it gets dark to see if the eclipse is already in progress or about to begin. The dark shadows of Io and Europa will pass in front of Jupiter over the course of more than an hour. The first shadow to enter onto Jupiter is Io's, while the one that tags behind is Europa's. Look for the four Galilean moons arrayed out to one side of the planet. Callisto is farthest away with Ganymede near it. Close in to Jupiter are Europa and then Io, which is the closest of all. If you are able to watch early enough, you'll get to see Europa and then Io appear off the limb of the planet after they have passed in front of Jupiter.
A partial solar eclipse is on tap for August, but it can only be seen from northern Asia and Europe. The next eclipse that will be visible to viewers in the U.S. is a total lunar eclipse in January.
Chance at a Comet
It's 4 a.m. in early August and you can't sleep. What to do? Grab a pair of binoculars, go outside before the sun rises, and find the northeastern horizon. Look to see if the constellation Gemini has emerged above the horizon yet (actual time of rising depends on your location). If you aren't familiar with Gemini and its bright "twin" stars, look for the better-known constellation of Orion rising in the east and then scan the horizon to the left (north) until you see the bright pair of stars, one above the other. From August 4 to 6, a brightening comet known as C/2017 S3 PanSTARRS will be traveling between the top star, Castor, to the bottom star, Pollux. If the comet increases in brightness as predicted, you won't even need the binoculars to see it.
The comet will stay close to the horizon, reaching perihelion on Aug. 15, when it should be at its brightest. However, a surprise outburst in July, which gave it a quick brightening and greenish hue, may have knocked the stuffing out of its August showing. Unfortunately, mid-August is also when the comet is closest to the horizon and the rising sun, which might wash out your view. But if you're awake, it's worth taking a look. Perhaps it will have another surge as it gets to within just .21 AU from the sun, a final hurrah, before it most likely disintegrates.

In 1991, the Bay Area Air Quality Management District launched a Spare the Air program to keep residents in the San Francisco Bay Area informed of high ozone-level days, when air is smoggy and exposure to poor air quality poses health risks. Now, the air district might need to update its alert system for something other than just ozone: antibiotic-resistant genes (ARGs).
A team of researchers from the U.S., China, South Korea, Switzerland, and France examined air samples from nearly two dozen cities, including San Francisco, Paris, Warsaw, Zurich, Beijing, Brisbane, and Seoul. They discovered airborne concentrations of antibiotic-resistant bacteria in each of the cities at varying levels, produced by concentrated animal feeding operations, hospitals, wastewater treatment plants and other sources.
Their findings indicate that antibiotic-resistant genes can spread from one bacterium to another, and that this bacteria has the ability not only to travel through the air, but to travel across continents, even across the globe—exposing millions of people to antibiotic-resistant genes whether they live in proximity to those sources or not.
"Common everyday human activities such as car traffic can kick up the bacteria and make them airborne," Dr. Maosheng Yao, a collaborating author of the study, Global Survey of Antibiotic Resistance Genes in Air, and professor of environmental sciences and engineering at Peking University, told Sierra. "Natural winds can also suspend these biologicals into the air."
For wastewater treatment, there is an aeration process that can make biologicals airborne. They are prevalent in areas where human consumption of antibiotics is widespread, such as in hospitals, or where agricultural practices rely heavily on the use of antibiotics.
San Francisco topped the list of the cities with the highest readings of antibiotic-resistant genes in the air.
"We used a novel protocol to get enough air samples from different world cities," Yao told Sierra. "That way we could tell where there were significant differences in levels of ARGs."
The report was published July 25 in Environmental Science & Technology.
Air quality indexes that evaluate how safe the air is to breathe focus on ozone, particulate matter (PM) such as the noxious pollutants emitted from power plants, carbon monoxide and other factors. Those indexes do not include information about antibiotic-resistant genes.
Yet a growing body of research increasingly points to pharmaceutically-polluted environments in cities worldwide, not just involving water or soil pollution, but air pollution as well. According to the new report, airborne pathogens in hospital environments have been found to be multidrug-resistant; indoor air samples taken in communities near animal-farming operations, where the use of antibiotics on animals is widespread, have been found to be rife with antibiotic-resistant bacteria.
For the latest study, Yao and collaborating researchers profiled 30 known genes that are resistant to common antibiotics, including tetracyclines and amingoglycosides, and examined air samples in 19 cities in 13 countries, each with different climate zones. To get their results, researchers employed an automobile air conditioning filter method to collect samples.
Beijing was found to have the highest complex mix of ARGs, with up to 18 different subtypes detected in the air. The most commonly detected antibiotic-resistant genes in all 19 cities were those with a resistance to β-lactams and quinolone antibiotics, with the highest prevalence found in San Francisco, which Yao speculated could indicate heavy use of antibiotics in hospitals there without the proper systems in place to control for airborne emission. The most powerful antibiotics on the market, which are supposed to be reserved for only the most serious medical cases, were detected in six of the 19 cities.
One of the most surprising discoveries from the study, Yao said, was the low level of ARGs in Hong Kong, possibly attributable to that city's high humidity level.
Infections from antibiotic-resistant bacteria including gonorrhea and MRSA pose a significant public health risk, with growing fears of the rise of so-called "super bugs." Public health warnings such as from the CDC often focus on the overuse and misuse of antibiotics, providing guidance on the most appropriate practice for prescribing and consuming those drugs.
These sources, however, provide little to no guidance around the possibility of exposure to antibiotic-resistant genes in the air.

Normally, a writer writes to reach an audience. But what I'm about to tell you, I want you to keep just between us, OK? Whatever you do, don't email this article to your friends, don't share it on Facebook, and please don't post it on Twitter. Because I'm going to let you in on one of the San Francisco Bay Area's best-kept backpacking secrets, and I want to keep it that way.
The place I'm going to tell you about is big enough, and still wild enough, to accommodate a week-long backpacking trip. It's a landscape that's textbook California savanna—a terrain of mammoth black oak and valley oak that, in the springtime, explodes into wildflower fireworks. And—best of all—it's a place that you can get to in a relatively painless two-hour drive from San Francisco or Oakland.
I'm talking about Henry Coe State Park, the largest state park in Northern California. At 88,000 acres, it's about 25 percent larger than Point Reyes National Seashore, but it hosts a tiny fraction of the estimated 2.5 million visitors who travel to the national seashore every year. It's also stupid-close to the mish-mash of freeway mazes and sprawl that make up most of the Bay Area. As the crow flies, the park is a scant 35 miles from the Apple headquarters in Cupertino.
All of which makes Henry Coe the perfect escape. Once you get there, you'll feel far away—even if you're still close to home.
I should say that if you're the kind of backpacker who hungers for epic alpine vistas or the sharp beauty of the desert, you may at first be disappointed by Henry Coe. There's little grandeur there. No big peaks or stunning buttes, no rough rivers or knock-you-on-your-ass tall trees. It's a place of subtle charms. With its broad sweeps of tall grass and swooning oak trees, Henry Coe feels like it's ripped from a John Steinbeck novel, the epitome of Old California. The place is merely pretty—but after weeks stuck in the city or the 'burbs, pretty is more than enough.
At a good half mile above sea level, this northernmost outpost of the Diablo Range has a lushness unusual for Californian savanna. Gray pines are scattered among all of the oak trees. There are ponderosa, including a few giants that seem like they've been transplanted from the kneecaps of the Sierra Nevada. Coyote Creek, one of the park's main arteries, manages to flow even through the dusty days of August and September.
Then there are the flowers—my God, the flowers. My field guide, Wildflowers of Henry Coe State Park, features 67 species. If you time your visit for late winter or spring, you'll be gobsmacked by the chaos of colors: blue lupine, pink and red paintbursh, football field lengths of orange poppy, crimson columbine, yellow fiddlenecks arching their heads above the grasses like herds of giraffe. There's purple everywhere: purple owl's clover, purple shooting stars (two different types), purple clarkia.
You've got a good chance of seeing some wildlife. Henry Coe's usual critters are common: deer and coyotes, flocks of turkeys zigzagging through the understory. If you behave yourself (that is, if you're practiced at being still) you might catch something more elusive. Once, I spotted a red fox, jumping through the beam of my head lamp. On another trip, I came across a bobcat, right in the middle of the trail. During a New Year's solo trip, I saw a feral hog above Coit Lake. It was the size and color of a wine barrel, tearing up a hillside with the speed of an NFL linebacker.
If you really want to play with solitude, Henry Coe will demand some work. Anything within a day's hike of the visitor center at Coe Ranch is reliably busy with day-trippers, crews of college backpackers, and mountain bikers a'shredding. (Many of the park's trails are old ranch roads, broad and with a brutal grade, which makes them popular with the two-wheelers.) But if you go farther afield, it gets lonely quick enough. Few folks make it out to the Orestimba Wilderness, a 22,000-acre state wilderness punctuated by the impressive chert outcropping of the "Rooster Comb," where miles-long groves of blue oak cast their candelabra arms skyward. I doubt more than a dozen people a year make it to the old corral below Bear Spring.
Did I mention that if you live in the Bay Area, Henry Coe is ridiculously easy to get to? The proximity is the point. Often as not, the backyard beats the bucket list destination. I've backpacked through Henry Coe nearly 10 times, and its lack of pretension has grown on me. At this point, it seems like an old friend.
I'd encourage you to start planning your route. Just remember: You didn't hear this from me.

Where: Henry Coe State Park. Take California Highway 101 to the city of Morgan Hill and exit at East Dunne Avenue. Follow Dunne Avenue eastward, and follow the park signs up into the hills.
Best Time to Visit: Spring is the most popular season for visiting Henry Coe, on account of the explosions of wildflowers. If you want to beat the crowds, consider visiting in winter, when the grasses are typically green and lush and the temperatures still relatively mild. The park can be punishingly hot and dry in the summer, and water difficult to come by.
Backcountry Hack: Each spring, the park hosts what it calls "Backcountry Wilderness Weekend," when park staff and volunteers from the Pine Ridge Association organize a shuttle system along the old ranching roads to establish a temporary trailhead on the east side of the park, affording hikers and equestrians easy access to the Orestimba Wilderness. Downside: The typically quite-far reaches of the park become packed with people. Upside: It's a good way for families to get to places like the Rooster Comb, which requires at least two days of hard trekking to reach.
Bring Your Fishing Pole: If you're an angler, consider bringing your pole. There's good fishing—bass, crappie and sunfish—at Coit Lake and Mississippi Lake. But both lakes are fringed with thick stands of tule reeds, so getting to a good place to cast requires some bushwhacking.
Pro-tip—Brave the Narrows: Many backpackers or hikers seeking to get from the park headquarters to the eastern side of the park will avoid the narrow gulch of Coyote Creek marked on the map as "The Narrows" and will instead take the punishing ranching roads up and over the ridges. But if you're a half-experienced trekker, you should brave the Narrows (unless it's after a big rain). Between Poverty Flat Campground and China Hole you'll be rewarded with a sycamore-strung single-track free of mountain bikers. In the spring, the pools between China Hole and Los Cruceros are often filled with various species of duck.

I'm sitting on a ridge at 9,000 feet, overlooking the world's largest alpine valley. The mid-June sun drops behind a nearby cliff band and the clouds shift, leaving errant rays of light shimmering in the passing agricultural vehicles' dust trails. Behind me, a fence blocks access to a yawning hole—the entrance to the decades-defunct Orient iron mine—from which tens of thousands of bats should start emerging any minute now.
I love being in the humbling expanse of the San Luis Valley. Its conservation-focused ethos gives me hope at a time when optimism often feels foolish. Tucked into the western foothills of southern Colorado's Sangre de Cristo Mountain range since 2001, the nonprofit Orient Land Trust has labored to preserve this valley's pieces of human history, push for sustainable farming, and protect habitat for several species of animals, including the massive colony of bats that take over the abandoned Orient Mine each summer.
"What is that smell?" asked my husband Mike, approaching my perch from a patch of scrub oaks. I look around, shrug. Then, the ammonia hit my nostrils.
Scott, our guide for the night—and an amateur biologist and volunteer with the OLT—quickly pipes in, explaining that that the odor, which is reminiscent of a pit toilet and comes in waves over the next hour or so, is simply guano. In preparation for the night's hunt, bats void their bladders and bowels before taking flight. Any minute now, Scott said they should start the flight out, so I lean back, watch the sky turn pink and wait, listening to chirps of swooping swallows, yips of distant coyotes, and the excited chatter of 23 human strangers, all here for the same show.
It starts suddenly: A stream of Brazilian free-tail bats (pictured, right, courtesy of iStock/the4js) splits the sky above my head. And as people's voices fall away, the only sound left is the river of wings. Throughout the night, they'll dine on moths, beetles, and other insects that inhabit the valley's agricultural wetlands and nearby hot springs. The critters weigh roughly half an ounce and have wingspans averaging 13 inches. Since this particular roost is composed mostly of males who have temporarily separated from larger colonies of females, most of whom are busy lactating and rearing their newborn pups, it's considered a bachelor colony. Females give birth in June, and since males don't help raise their young, they typically split off during this period. The Orient Mine bachelors' counterpart maternity colony summers further south, in New Mexico's Carlsbad Caverns
In fact, The Orient Mine hosts not only the largest bachelor colony of Brazilian free-tail bats in North America (interestingly, bachelor colonies are typically much smaller, numbering in the hundreds or low thousands), but also the highest in terms of elevation. The migratory mammals have been spending summers here since at least the 1960s. They usually arrive from Mexico in mid-June and return south via Carlsbad Caverns by the end of September, but this year's exceptionally dry, relatively warm winter brought them early, and in unofficial but unprecedentedly high numbers.
As soon as we left our camper in Moffat, Colorado's Valley View Hot Springs and set out on the trail that climbs 700 feet to the Orient Mine, Mike and I began noticing plenty of evidence of the region's chronic aridity and acute drought—the valley saw less than half its usual snowfall this winter, and the Rio Grande is running at 20 percent of its 120-year average. Early summer in the San Luis Valley is usually wildflower season, but the only visible blooms, pale yellow ones, unfurled from the prickly pear cacti at my ankles. As we hiked, the rain clouds we saw streaking black over the valley provided a guessing game: Were they scattered thunderstorms? Or (more likely) signs of virga, a form of precipitation that reaches toward but never quite touches the earth?
About a third of the way into the hour-long hike, the main trail veered right and massive piles of rust-colored tailings came into view. From 1880 until its closing in 1932, the Orient Mine produced two million tons of limonite and supported more than 400 people. Cutting through the piñon-juniper forest, smaller paths lead to old foundations and rusted barrels—the ruins of Orient Town.
The bats were first recorded in the Orient Mine about 35 years after extraction operations ceased. Ever since, they've been roosting throughout the small caverns that shoot off from the main cave, where temperatures stay consistently cool and the labyrinth provides shelter from potential predators. The bats' nightly hunts, coupled with the valley's dry climate and bitter winters, reduce the need here for agricultural pesticides.
According to OLT Executive Director Doug Bishop, the 2,200-acres it protects are home to common Colorado wildlife such as weasels, elk, and pronghorn, as well as two threatened species of fish—the Rio Grande Chub and the Rio Grande Sucker. Near the hot springs, the humidity and warm waters create a microclimate that supports a rare mountain orchid, a hot springs endemic snail, and one of Colorado's few populations of fireflies. The organization encourages responsible stewardship of this fragile, high desert environment. Beyond teaching visitors about the bats at Orient Mine, they operate the cabins and campground at Valley View Hot Springs using hydroelectric power, and lead educational hikes and programs at Everson Ranch—a nearby historic homestead where the OLT runs sustainable agricultural and green energy projects.
As the light fades, the bats become harder to see, but I still know when they pass. Their wings move through the air like a whip when they buzz my head. It's difficult to know exactly how many leave the roost on a given night, but estimates put this colony between 100,000 and 250,000 individuals, depending on the month and year.
The bats flow from the cave for 45 minutes, almost twice as long as they will later on in the summer, as the season peters out. At first, they follow one another's echo-location, forming a tight ribbon that zooms toward the valley floor. As their numbers thin from about 100 bats per second to 40, the stream widens and they begin moving independently. "[When there are fewer bats] it's easier for them to hear the moths, so they can follow them instead of each other," said Scott. "That's why they seem more erratic."
At 9:14 pm, as suddenly as the out flight began, it's over. We pack up and don headlamps for the 1.5-mile hike back to the Valley View Hot Springs campground. Stars emerge, bright pinpricks in the inky moonless sky. After leaving our bags at the campsite, Mike and I wind through the woods to take a final soak in the hot springs, tracing steamy streams lit by fireflies that wink along their banks. As I sink into the warm water, constellations shimmer on its glassy surface, and I feel the air shudder as a bat wings past my ear.

Where: The Orient Land Trust in Moffat, Colorado
Getting There: It is roughly 200 miles (about a 3.5 hour drive) from Denver to the Orient Land Trust and Valley View Hot Springs Welcome Center. From there, the hike is approximately 1.5 to 2 miles, with a 700- to 800-foot elevation gain. I recommend the free guided hikes OLT offers nightly throughout the summer (weather permitting). Valley View Hot Springs is well equipped as a home base for the hike, with cabins as well as campsites for RVs, campers and tents, but it fills up early.
Best Time to Visit: mid-June through September
Fees: The hike is free. Overnights at Valley View range from $10 per night to $75 per night, plus a $30-per-person soaking fee.
What to Wear: OLT and Valley View are clothing-optional (this goes for the hike up to Orient Mine, too). However, Colorado weather can be mercurial, and temperatures drop quickly after dark, especially at 9,000 feet, so whether you choose to wear clothes or not, bring layers for rain and warmth, plenty of sunscreen, a hat, and a headlamp for the return hike.
Respecting the Wildlife: To avoid disturbing the bats during their out flight, don't use flash for videos or photography, keep your movements calm and quiet, and speak in low voices, or not at all.
For More on Bats: Check out Sierra's most recent slideshow featuring various bat species that were photographed by veteran biologist and photographer Merlin Tuttle.

You can't protect an animal that you don't know exists. Tapanuli orangutans, for example, are found only in the Tapanuli region of Sumatra; they were only identified as a species last year, when scientists found them to be genetically different from other Bornean and Sumatran orangutans. With just 800 left, this newly discovered species is the most critically endangered ape.
It's hard to believe that with only seven great ape species on the planet—Tapanuli, Sumatran and Bornean orangutans, eastern and western gorillas, chimpanzees and bonobos—a species could have gone undiscovered until 2017. But, in fact, new research shows that many mammals still fly under the radar.
The olinguito, a carnivorous member of the raccoon family, wasn't discovered in Colombia and Ecuador until 2013. The Burrunan dolphin was found in the waters off Australia in 2011. In a new study published in the journal Ecology and Evolution, Molly Fisher and other researchers at the University of Georgia used a predictive model to conclude that 303 mammals have yet to be discovered.
Most of these unknown mammals, the researchers found, are likely in tropical regions of the world, many of which are threatened with habitat destruction. This makes discovering them a race against time before they go extinct. "If a species goes extinct before we discover it, how can we know what went wrong? If we lose a species without knowing it existed, we lose a lot of information," said Fisher.
Fisher said that she chose to study mammals because they are the most charismatic of terrestrial species, and therefore more likely to be protected. But less glamorous creatures, like plants and arthropods, are disappearing at even faster rates than mammals, which is worrying to scientists.
"We're concerned about why extinction rates are on the rise," said Fisher. "We're losing a lot of biodiversity, most of which exists in our remaining forests in places like the Amazon." Some researchers now talk about "biological annihilation," citing cascading extinctions, dwindling population sizes, and range shrinkages among vertebrate species.
Sumatran Orangutan Conservation ProgrammeMaxime Aliaga
Fisher and her team employed scientific modeling to measure discovery and extinction rates. Without direct interaction, however, it's impossible to know whether a species has disappeared completely or just hasn't been seen in a while. This occurred recently with the Guadalupe fur seal, a species found in California and Mexico that was rediscovered after years of suspected extinction.
The model used by the University of Georgia researchers is similar to one used to predict the remaining unknown number of plant species in 2011. It was constructed by counting the total number of species discovered and described by scientists from 1760 through 2010 by five year increments. "The model utilizes a statistical technique called 'maximum likelihood,' which allows scientists to approximate the total number of species that are likely to have existed in order to produce the number of descriptions actually recorded by taxonomists, scientists who classify new species," said Fisher.
As the number of such scientists has increased, so has the number of classifications accounted for in the model. The researchers also noted "taxonomic efficiency" or how good scientists are at discovering new species. Like the Tapanuli orangutan, many species once thought to be identical are, upon closer inspection, found to be genetically distinct. Dr. Michael Krützen from the Department of Anthropology at the University of Zurich was part of the team that helped discover the Tapanuli using genomic analyses from orangutan samples. He said that Tapanuli orangutans differ significantly, most notably in tooth and skull shape, from those outside the region, because their populations had been disconnected for at least 20,000 years. But with so few of them left, it's easy to see why the species wasn't discovered until recently.
Fisher and her team approximate that 5,860 mammal species currently exist. She was surprised to find that Europe and Asia had a significant number of undiscovered mammals. The model showed that 10 percent of species in this part of the world have yet to be discovered, possibly because many are located in lightly populated Siberian regions.
