    As expected, the U.S. Department of the Interior on Tuesday released a final rule that reverses Obama-era restrictions on methane emissions from oil and gas operations.

    Barbed Wire and Redrock at Bears Ears National Monument

    By David Gessner 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.
