Go up the Dead Snag Rappel. Easy, but runout climbing to the first set of chains (don't stop here). The best line goes straight up from the chains, but you can go slightly left for easier climbing (and less pro). Follow the right crack past a small bush to the right edge of the roof. Gain the roof through either of the two notches on the left. Ascend the small dihedral to the ledge, or come out onto the face when convenient. Beware loose rocks.
