Steve Cheney told me this was 10C. The complete line follows the crack to the off-width roof and hand crack. Above this another offwidth roof leers with and evil slot above. When I did the upper slot, it appeared not to have been visited since 1983. One can lessen the pain by skipping the first OW an climbing the arete. The complete climb is just plain hard- the initial pitch is probably the easiest. Bring a big bro.
