Caribou, also known as tutu, traverse the snowy heart of Alaska’s Brooks Range near the Nunamiut community of Anaktuvuk Pass. 'Anaktuvuk' means 'the place of many caribou droppings,' and the pass lies directly along the traditional migration routes of the Western Arctic and Teshekpuk caribou herds. Each spring, thousands of caribou begin their journey across the North American Arctic toward their calving grounds. Anaktuvuk Pass, now part of Gates of the Arctic National Park, is home to the inland Iñupiat people known as the Nunamiut, who have relied on caribou for millennia—not only as a primary food source but also as a vital part of their culture and spirituality. The community was established in 1957, when the Bureau of Indian Affairs compelled the Nunamiut to settle in a single village; before that, they lived a nomadic life closely tied to the rhythms of the caribou migration.
