Mount Clark, Southwest Face. This long face was first climbed by Joe McKeown and me on August 19. We began just left of the single chimney system and climbed some 200 feet to loose blocks where we traversed into the chimney and ascended to an alcove. We continued up and left, nailed a short crack, then traversed right into the chimney again and climbed about 200 feet (with a belay in slings) to a ledge where we placed a bolt. From the ledge, a 30-foot pendulum brought us to a small dihedral, and mixed climbing led to its top at a ramp. We followed the ramp up and right, across the chimney, to the south ridge. Staying on the east side of the ridge, we climbed mixed and free up and right for a pitch. Easier climbing led up for three pitches to the summit. NCCS IV, F8, A2.
