Colorado Choss

About

Colorado Choss is a rock climbing area located near Grand Junction on Colorado's Western Slope. The site consists of loose, crumbly rock formations known as choss, offering routes suitable for climbers with easy skill levels. The primary feature is a distinct pile of rocks called The Chosspile, situated directly above Rimrock Drive. Climbers can access the area via parking on site and a short hike of approximately 1/16th mile to the base of the climb. The elevation is listed as 4,576 feet in database records, though one source cites 7,334 feet. The area is open for visits year-round. Parking is available, and pets are allowed. Protection involves small gear, with medium cams or hexes needed for the top section of the route. A band of webbing with a rap ring at the summit aids in descent. The climbing style is primarily traditional (trad), with specific routes measuring around 35 feet in length. The location serves as a local climbing hub within the Grand Junction area, which is the largest center on the Western Slope.
