An amazing slab climb up the left edge of the buttress, long, varied and involved, albeit with a very serious start. Take a lot of small-medium cams, wires, and extenders. Currently poorly described in the topo. Start at the bottom on the slab, just right of the arete. Climb up and leftwards via small crimps and pitiful RPs to a slab on the arete. Continue up the arete past reasonable protection to a high triangular ledge. Traverse right on pockets beneath the overlap and make committing moves over this to gain a small rightwards ramp, then the main leftwards ramp. Finish up a ledgy crack above.
