Well named, I think, due to the fact that the starts are all conglomerated rock (rock with little nasty sharp pebbles in it). Regardless some very good moderate to hard climbs can be found. To climb here, you better have some good shoes and tough fingers. No picture is available yet.
From the parking area, walk toward the valley to the Fireplace, turn left and follow the trail into the next formation, trend right and down to bottom of the cliff, turn left. Go past Sun Wall and the Sand Trap and look for a door through the rock. Inside you'll be at The Whipping Post
