Westwater Canyon is carved by the Colorado River through the desert of the eastern Colorado Plateau.  The Colorado Plateau spans a large area surrounding the intersection of the borders of Colorado, Utah, New Mexico, and Arizona and is flush with numerous geographic wonders.  The basement rock in the heart of the canyon reveals exposed black granite from the Proterzoic era; rock 1.75 billion years old found in few places on the Colorado River outside of the Grand Canyon. The upper canyon is composed of sandstone.  Bring your geologist friends and let them gush effusively over the impressive unconformities and textbook examples of geologic uplift as you float through this remarkable desert canyon.

Suggested river levels for paddling this section of the Colorado River are between a bare minimum of 1,000cfs and a high of 16,000cfs. River conditions sourced from USGS 09180500, the Colorado River Near Cisco Remember only watercraft are permitted at Westwater.
