BLM Desolation Canyon Wilderness Study Area

Eighty-four miles of wilderness whitewater through the deepest canyon in the Uinta Basin — deeper than the Grand Canyon at its maximum point. Desolation Canyon is one of the great multi-day river trips in North America: Class I–III rapids through 2,000 feet of layered sandstone, cottonwood groves sheltering ancient Fremont rock art, bighorn sheep on every cliff band, and not a road or power line for the entire run.

Trip sections
Sand Wash to Rock Creek — 28 mi, Class I–II, canyon entry and Fremont rock art
Rock Creek to Three Fords — 28 mi, Class II–III, deepest canyon section
Three Fords to Swasey Rapid takeout — 28 mi, Class II, widening canyon and desert benches

Data Quality

River conditions are community-verified. CFS ranges, difficulty ratings, and trip sections may not reflect every flow level or seasonal change. Always check current conditions, scout unfamiliar rapids, and paddle within your skill level. If you spot an error, use the Improve This River button at the top of the page — your local knowledge is what makes this atlas accurate.
