This is another fingery area classic. Patience and good footwork will see you through. Start up a mungey, broken crack system. After about 10 feet, move into a very thin crack that continues to the chains. The crux consists of tenuous moves on insecure locks and is found about half way up.
Located about half way up the gulley, about 20 feet left of a prominent large pine tree. Look for the Kiss-like green tongue of vegetation that marks the start.
Thin to #1 with an emphasis on small nuts and cams will do.
