Cheesebox Canyon

verified ACA 3B High flood risk Blanding, UT

A 5 mile multi-pitch Cedar Mesa descent with zero to five rappels, swims, a hidden arch grotto, and a tight rabbit-hole section, all reached via a long 4WD approach.

Often called one of the top three technical descents on Cedar Mesa. Anchors range from R to X exposure on the downclimbs; bring webbing and rappel rings to replace any tat that looks old. Pair with Owl Canyon (already in atlas) for a Cedar Mesa weekend; the two descents share approach logistics but are different drainages.
