This long pitch crosses a large face via an arching left to right crack. Climb the crack with nice jams interspersed with long moves, mostly smearing for feet. About 1/2 way across you encounter the crux, with hard "horizontal laybacking" off a rail. This type of movement continues until you can jam again, almost at the end of the traverse.
This route is located on the east side of the Butler Corridor. If entering from the North (the best approach) it is the first known route on the left. Start on boulders to the left of the crack, which doesn't quite reach the ground.
Full rack, doubles in .5 - 2 Camalots, keep a #1 Camalot for the last piece. It's tipped out, but the best thing you can get (5.7 climbing).A #4 Camalot is nice for the end of the traverse.
