Class I-II North Fork Koyukuk River, AK

This river flows from the south flank of the Arctic Divide through broad, glacially carved valleys in the rugged Endicott Mountains of Alaska's Central Brooks Range. It passes between the "Gates of the Arctic" at Boreal Mountain and Frigid Crags.

The combination of demanding whitewater in the upper river region and a gradient of vegetation changes—in addition to the river’s clear water—provides an interesting and desirable rafting experience
