The Inuvialuit and Gwich'in peoples spend their summers fishing off the coast of Canada's Yukon Territory. For generations, they've trekked from towns around the Western Arctic to a spit called Shingle Point, where the Mackenzie River's braided flows spill off North America into the Beaufort Sea. The nutrient-rich waters at the mouth of the Mackenzie are fat with marine fish, drawn in by the brief abundance of Arctic summer. Indigenous families subsist on these fish and other wild resources throughout the warm months.
