Approach the North Columns by walking up the left side of the formation to a large flat ledge below the climbs. Most of the climbs are cracks but there is a bolted face climb. One does need to lead something to set the TRs.
The climbs from left to right.
approach pitch (5.7): this pitch gets one to the top of the cracks. TRs can be set here.
crack #5 variation (5.8): this is the left portion of the Y.
crack #5 (5.9): this is a great hand crack, follow the right leg of the Y. There is a fixed anchor here.
crack #4 (5.10): follow a shallow crack weakness and go over the left portion of the roof (large cam needed if led).
crack #3 (5.9): follow the crack weakness and traverse right and around the roof (large cam needed if led).
crack #2 (5.8): start as in crack #1 but go left up the face to the top.
crack #1 (Baskin Robbins) (5.8): climb the large crack (chimney & off width) in the corner but stay in the crack to the top. There is a fixed anchor here. Go through a short tunnel to the start of the climb.
bolted arete (5.9): go up the blunt arete to the right of crack #1 and share anchor with crack #1. This was an old TR.
