The Clear Fork is one of the ultimate whitewater challenges in the state. Anyone attempting this run should have extensive experience in Class V whitewater and be comfortable with tricky boulder gardens, big drops, and deep canyons where portaging or hiking out can be impossible. This run is essentially one long series of rapids and myriad other hazards in a beautiful and deep basalt canyon. Scouting is a must and you will likely need several somewhat lengthy portages. The put-in access is rough and undeveloped.
