Permits are not required. However, extreme planning should occur before rafting this section. Rescues can take many hours due to its inhospitable terrain. Suggested flows are 125-150ccf. Flows lower than this will require dragging your boat or raft across sand bars. Water should be brought. Due to the high silt content of the river, filtering water can be near impossible. Do not use the river if there is flash flood potential. Be sure check weather for upstream river sections.
Named by John Wesley Powell during a mapping expedition in the late 1800s, this river and its many tributaries offered an impregnable fortress hideout for Butch Cassidy and other outlaws during the early 1900s. Today backpackers and canyoneering enthusiasts retrace the steps of these early explorers. This area still offers a primitive opportunity where self reliance and pre-planning are required. (BLM)
