This climb takes the corner up the steep face of the left hand buttress to the right of Mahon Chimney.
1. 10 m. Climb up left hand side of the slabs to a large grassy ledge at the base of the corner. Belay.
2. 30 m. Climb up the corner until it is possible to step left onto a ledge after the first overhang. Regain the base of the undercut corner (crux) and continue up the corner until it is possible to exit up the left hand wall.
