Tobin's Dihedral

Eye-popping 200-foot tall dihedral.

P1 (5.10++, 160 feet): Fifty feet of endurance laybacking (with VERY slippery feet) leads to a no-hands rest out on the face. Eighty more feet of easier laybacking with excellent footholds leads to a class-4 trough. Belay thirty feet higher on a small ledge, where the class-4 section ends.

P2 (5.9, 120 feet): Continue up the dihedral to the top of the giant pillar. Runout face climbing leads up and left to a bolted belay. From here, easy fifth class leads to the top of the Dome. It is also possible to make two rappels down Between Nothingness & Eternity (two ropes required).

Right smack in the center of the Dome. Unmistakable.

On the first pitch, the crack starts 6-inches wide and slowly tapers to about 3/4-inch (the first fifty feet of endurance climbing is all 4-6 inches wide). The first belay takes 0.5-1 inch.
