This route is located on the left side of the slabs below Sphinx Crack. It is the leftmost slab route. Although the top is just a solo up 5.5 terrain the crux areas down low are great fun and reasonably protected (as long as the 1/4" bolt survives the short fall you would exert). If the bottom slab continued I would consider this a great route.

Crimp up small edges on perfect slab up to the flake, place a small cam and hop up. Clip the bolt, and slab out right and up on knobs and a few edges. Once you are on the lower angled rock, the hard climbing is over. Angle up and left toward two bolts above a ledge. I don't remember placing another piece until just before the top. You could groundfall from the upper section.


One old bolt and a small cam in the flake/ramp. Another medium piece near the top. I think that was it!

David Bell put this up I don't know the date, sometime in '80' or '81. He climbed it with a girl he went out with at the time. I do not remember her name. The slab was always good bouldering, and on a whim, he drilled it. It is a 1/4" x 1 1/2" Rawl drive. It should be a Leeper hanger.
