Open Book ascends a massive dihedral on the south face of Disappointment Peak, above Garnet Canyon, about an hour and above the Lupine Meadows trailhead.

Its seven pitches are steep, hard, and intimidating. Overhangs, cracks of all sizes and varieties, under-clings, laybacks, and serious exposure are the order of the day, and retreat is difficult. Easier or more difficult variations are possible.

If you are a strong 5.9 climber, you will have a ball; if not, you will wish you were some place else. Fortunately, the descent is easy and soon you will be crowing about the climb over pizza and beer—if you can still hold your beer.
