There are two possible places to start; one that's well-protected but difficult, and a second that's easier but poorly protected. I couldn't do the first, and climbed the second. Tiny RP's give questionable protection. Above the start, hand and fist jamming in the back of the strongly overhanging, flared chimney makes the climb worthwhile.
This is about in the middle of the wall. A strongly overhanging flared chimney at mid-height is easy to pick out.
gear to 4 inches, plus some tiny RP's for the start
