Chiquito Dome, Mammoth Pool Reservoir, “Archline”. In May, 1979 Conrad van Bruggen and I climbed a new route that starts from a large flake just left of Jigsaw Puzzle (A.A.J., 1979). From the top of the flake, go past a bolt and cross a very thin crack (which continues 600 feet to the top) to a sling belay just right of an arch. Climb up, then left, recrossing the crack, to the crux just left of a second arch. On the next pitch rejoin the crack at a third arch with an easy roof move and belay higher. Two easy pitches follow the crack to the top. (NCCS II, F9.)
