Summer along the Kobuk River is a story of abundance. From May through September, the snow and ice retreat, the sun shines nearly continuously and the valley comes to life. Millions of insects thrive in ponds formed from melting snow trapped by permafrost, and grasses, willows, sedges and lichen flourish in the warm Arctic sun. Iconic Arctic animals like grizzly bears, wolves, wolverines, foxes, porcupines, moose and more can be seen darting across the tundra and lumbering through the woods in search of food.

Every summer, the chum salmon return from the ocean to their spawning grounds within the valley. They return vital nutrients to the river and bringing food to the people who live along its banks.
