The Great Kobuk Sand Dunes, Little Kobuk Sand Dunes and the Hunt River Dunes are remnants of dune fields that covered as many as 200,000 acres (81,000 ha) immediately after the retreat of Pleistocene glaciation. A combination of outwash deposits from the glaciers and strong winds created the field, which is now mostly covered by forest and ...
Rolling, vegetated sand dunes were formed by the last retreat of the glaciers. These dunes are the remnant of a much larger system that once included the Great Kobuk Sand Dunes to the north. This area is a transition zone where the northernmost boreal forests give way to open Arctic tundra.
Kobuk Valley protects 61 miles (98 km) of the Kobuk River and three regions of sand dunes. Created by glaciers, the Great Kobuk, Little Kobuk, and Hunt River Sand Dunes can reach 100 feet (30 m) high and 100 °F (38 °C), and they are the largest dunes in the Arctic. Twice a year, half a million caribou migrate through the dunes and across ...

The Kobuk River is a periglacial river, fed by a remnant glacial lake (Walker Lake) and mountain snowmelt in the Brooks Range. It cuts a channel through a landscape otherwise dominated by permafrost. The Kobuk's current form and structure is a direct result of several stages of erosion and channel formation following the last glacial retreat.
Local landowner Michael Patterson is pursuing his vision for a new campground near Sand Pond in Sanford, Maine. The association has approximately 50 members so far, according to Dumont.
The southernmost portion of the park includes the Kobuk-Selawik Lowlands, with the headwaters of the Kobuk River. The Brooks Range has seen repeated glaciation, with the most recent called the Itkillik glaciation from about 24,000 years ago to roughly 1500 to 1200 years before the present. [14]
