A 25' rattly fist to cupped hands, roof-crack boulder problem. The crux lies at about the 15 foot mark, and the crack never gets more than four feet off the ground.
Unless you have big fists, the only solid jams are about a foot deep in the crack. In my opinion, this is one of the best crack problems in the park. WAY worth the hike (and drive if your coming from the valley).
Location
Walk about a mile on the Cathedral Lakes trail, break left off the trail onto a semi-noticeable trail that heads towards a big buttress. The Ghettosnake boulder lies in the trees at the base of the left side of the buttress. There are also directions in the Reid Tuolumne guide
Protection
Long sleeve shirt, Tape. Both optional but highly recommended.
Tried this last summer. It was sick. We were all bloody from tips to elbows. Found a decent boulder with a few cool climbs on it a few hundred feet to the right if your looking at the slabs. A cool roof. Probably V3, and V1.
