There are three tiers of roofs formed by three boulders to the left of the Andrew boulder. From the left-hand side of the middle roof, sit start with your right hand on a sharp right flake and your left hand on the lip of the roof. Grunt your way along the lip of the cave to the right and top out.
Under the roof formed by the boulder leaning up against Andrew boulder above the lower roof boulder.
Spotter to keep you from falling off the lower roof to the ground if you fall backward while pulling the roof.
