Approach as for Clouds, and move to the left to the base of a left-arcing crack/seam. The crack begins at 5.6, and as it arcs to the left it eases to 5.3, but closes to a seam and becomes fairly run-out. Continue traversing to a shallow left-facing corner to the right of Initiation Crack. Climb up the corner, following a 5.8 fingertips crack, to where the corner peters out. Traverse up and left over run-out 5.7 terrain to the Claustrophobia Crack/Initiation Crack belay.
A 50m rope, some quickdraws and short slings, a few small to medium hexes or cams, and a good assortment of small to medium wallnuts or stoppers (wallnuts, with their asymmetry, work better in the 5.8 corner).
