The Dirty Devil. A major tributary of the mighty Colorado, I've been wanting to tour the length of this wild desert river for long time. The canyon itself is little else than a vortex where eons of sand are moved down-steam on a daily basis. Gouged by water and sculpted winds, you can literally see the canyon walls change shape. Many of the Dirty Devil's side canyons are highly developed slot canyons that create a branchwork system that would take lifetimes to explore. With only a long weekend to work with, myself and two other buddies set out to paddle down the main river channel and explore a few select side canyons along the way.
