Kobuk River

The Kobuk River is a 280-mile (451 km) river in northwest Alaska that rises in the Endicott Mountains and empties into Hotham Inlet of Kotzebue Sound. Its lower reaches cross Kobuk Valley National Park, and 110 miles of it are a National Wild and Scenic River.[1]

Course

The headwaters lie in the Endicott Mountains just north of the Arctic Circle, east of Walker Lake, which is commonly assumed to be the source but is not. The river reaches Hotham Inlet about 30 miles southeast of Kotzebue through a broad delta.[1]

Communities and park

Kobuk, Shungnak and Ambler are inland villages along the river and Kiana lies near the delta. In its lower reaches it crosses Kobuk Valley National Park, which contains the 25-square-mile Kobuk Sand Dunes.[1]

Course

The Kobuk River, called Kuuvak in Inupiaq, is about 280 miles long. Its headwaters are in the Endicott Mountains east of Walker Lake, within Gates of the Arctic National Park and Preserve. It flows briefly south through Upper and Lower Kobuk Canyons, then turns west along the southern Brooks Range through a wide wetland valley and empties into Hotham Inlet of Kotzebue Sound, about 30 miles southeast of Kotzebue [2].

Villages

Kobuk, Shungnak, and Ambler lie in the valley, and Kiana sits downstream near the delta [2].

Kobuk Valley National Park

The lower river runs through the park between the Baird and Waring Mountains. The park holds the Kobuk Sand Dunes, about 25 square miles, and part of the Western Arctic caribou herd uses the valley as winter range [2].

Wild and Scenic River

Congress designated 110 miles of the river downstream from Walker Lake as a wild and scenic river in 1980, and it is a popular floating destination [2].

Name and history

Kuuvak means roughly great river in Inupiaq. People have lived along the river for at least 12,500 years. During the 1898 Kobuk River Stampede about 2,000 prospectors arrived, but little gold turned up [2].
