Back Scratcher

Sit start (same as the DC Proj) on undercling rail left of the crack and traverse right until you get to the large protruding overhanging face. Take the small shallow holds up to the juggy rail halfway up the boulder then traverse right all the way to the right arete. Top out using the juggy stuff on top of the right arete. There are many variations possible, but this is the longest I could find and the most obvious (path of least resistance) on the boulder.A more direct line could go using the slopers above the left arete, but doesn't seem worth the risk. If you fall from the top, you will have your back scratched pretty hard, and it probably won't even feel good.

On the Parasol boulder

Pads. The top is probably V3 or V4. Just don't blow it.
