Due to broken holds and lichen, this description differs from the older guidebooks to the area.
Start up the short, easy crack and before reaching the ledge, move right to a pocket-like jug and a flake or two that will help you reach the large shelf above. Mantle up onto the shelf and stand up to reach the start of a high and somewhat spooky flake system. Climb up the flakes to gain the slopey lip and make a fun mantle over the top.
This route climbs the face at the far right end of the Upper Cliffs just before reaching the trail to the top.
