As you follow the trail down from Are You Experienced? around the corner (not the chimney), there is a series of overhanging flakes. Start at the first one at the corner and use the flake to gain the edge. From there, climb the obvios series of finger holds up the face. The flake itself is probably a 5.6.
Lots of webbing and a couple of lockers. There are trees on top, but they are a ways back.
