About half way up Hollow Flake (5.6, 1 pitch) on Arch Rock (right of The Staircase) in Elevenmile Canyon. Another fun crack climb the follows a left facing dihedral to a two bolt anchor. There are several good possibilities from the two bolt anchor - climb Persistence (5.8, 1 pitch), or top rope / climb Zamboni Man on the flack just to the right.
