To the right of Wiessner's Rib is a prominant prow. This is Frenchman's Cap. You can either start by climbing Yvette (a classic 5.9+ crack in the slab below the prow) or scramble on the left to a belay below the main buttress.
Follow a broken buttress above, finishing to the right passing several old pitons to the crux overhang at the very top. Often toproped but a well protected lead.
