San Juan River
The San Juan River flows 383 miles from the San Juan Mountains of southern
Colorado through New Mexico and southeastern Utah to its confluence with
the Colorado River in Lake Powell. The permit-required reach from Sand
Island through the Goosenecks to Clay Hills Crossing is one of the most
archaeologically rich river trips in the American Southwest, featuring
Ancestral Puebloan cliff dwellings, petroglyphs, sand waves, and dramatic
entrenched meanders. Typically run as a 5-7 day float from Sand Island
to Clay Hills (83 miles) or a shorter 4-day Sand Island to Mexican Hat.
