This classic line may be easy if you have enough reach, or extremely challenging if you can't reach the horizontal rail. Start on a sidepull and jug at 6 ft, make a move into an undercling and make a big reach for the horizontal rail. The rail is good enough to cut if you need to. Continue up on a few small crimps to an easier topout.
On the left side of the boulder. Just right of "Nuns and Donkeys".
Pads and Spotters, helps to have a spotter up on the boulder behind in case you blow the topout.
