Kobuk Valley National Park

Kobuk Valley National Park in northwestern Alaska preserves a remote stretch of the Kobuk River valley north of the Arctic Circle, renowned for the Great Kobuk Sand Dunes, the largest active Arctic dune field in North America. Created as a national monument in 1978 and established as a national park in 1980, it protects an unusual meeting ground of tundra, boreal forest, river habitats, and caribou migration routes. The valley has supported human life for at least 12,500 years, with major archaeological evidence at Onion Portage. With no roads into it, the park remains largely undeveloped, defined by wilderness, subsistence traditions, and exceptional ecological diversity.
