Mount Thor, South Face. An interesting new route on the south face, to the east of existing routes, was done May 7 by William L. Putnam, Tom Cosgrove, and me. The route climbs a series of jam-cracks, with one aid pitch, on the left side of a prominent truncated buttress. The rock was very sound. Rappel slings indicated the route had been previously attempted. NCCS II, F7, Al.
