This area offers several high end bolted routes and some monsterous roof climbs. Knob Wall is a most excellent place for beginner leadsters to play there new gear. Alot of the starts are that yucky conglomerated rock and I think people tend to shy away from it so it's never as crowded as Sunwall.
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 by about 200 feet.
