West Side Rock offers numerous boulder problems as well as short top rope or trad climbs. The more popular named climbs are all on the valley side. One of the few chimney climbs at Sandrock is on this crag right where the corridor ends south of "Jaws" but to my knowledge goes unnamed.
From the parking area, walk south down the road, and West Side Rock is the formation on the left. It runs for several hundred feet down the road. Also can be reached from the open area just past Jaws Block and/or through the corridor.
