Class IV Kobuk River, AK

From its headwaters in the Endicott Mountains and Walker Lake, the river courses south and west through a wide valley and passes through two scenic canyons. In the upper canyon, you'll encounter some Class 4 rapids that need to be portaged (about 1/3-mile portage), and there is one section of Class 2-3 rapids in the lower canyon.

Kobuk means "big river" in the language of the Inuit. Native peoples have hunted, fished and lived along the Kobuk for at least 12,500 years, and the river has long been an important transportation route for inland peoples.
