Sourgrass is my club's adopt-a-trail and we were just up there for the opening. Afterwards we headed out to slickrock. Here's some pics from 2 weeks ago: http://www.robinhood4x4.com/gallery/sourgrass_5-8-04

Slickrock is open on the other side (the side witht the stairsteps) and is do-able to the actual slickrock portion. However, the river crossing was pretty high, it barely swallowed 35's.
