Sand, Rivers and Caribou
Kobuk Valley National Park is encircled by the Baird and Waring mountain ranges. The park provides protection for several important geographic features, including the central portion of the Kobuk River, the 25 square mile Great Kobuk Sand Dunes, and the Little Kobuk and Hunt River dunes.
Nearly half a million caribou migrate through the Park twice a year – north in the spring, south in the fall. Their tracks crisscross the 25 square miles of the Great Kobuk Sand Dunes. The lofty dunes are a sculpted desert in the middle of a wilderness of wetlands. The Kobuk River on the north side of the dunes winds roughly 61 miles through the park, providing a travel path for people and wildlife.
