Approach right of the 'Southwest Corner' route and along indistinct edges over a small overhang to the 1st ring. Via the slab directly to the 2nd ring. From there along the ledge left into a small dihedral, through it and hand-over-hand right to the ledge above the ring, up to a shelf and left along the rib to the 3rd ring. Directly along the ledges to the top of the pillar to the 4th ring and freely to the summit.
