Kobuk Valley National Park is enclosed by the Baird and Waring mountain ranges
The park protects several important geographic features including the central section of the Kobuk River, the 25-sqaure-mile Great Kobuk Sand Dunes, and the Little Kobuk and Hunt River dunes.
Sand created by the grinding action of ancient glaciers has been carried to the Kobuk Valley by both wind and water.
Dunes now cover much of the southern portion of the Kobuk Valley, where they are naturally stabilized by vegetation. River bluffs, composed of sand and standing as high as 150 feet, hold permafrost ice wedges and the fossils of Ice Age mammals.
Up to 1,500 feet wide, the placid Kobuk River falls a mere 2 to 3 inches per mile. Its valley provides important autumn and winter range for the western arctic caribou herd. Bands of bulls and cows may be seen here from late August through October as they migrate across the Kobuk River on their extensive annual migrations.
Native people have lived along the Kobuk for at least 12,000 years. Their history is best recorded at the Onion Portage archaeological site.
