Arthur and I climbed just to the left of this couloir. We went up the SF Trail to DryLake then went straight up. Pretty much hugged the ridge all the way to the summit plateau. We bivied on the summit for the night.
Day climbed the central left couloir on the north face of San Gorgonio with mdostby and Charles Irving. Snow conditions were soft, but it was manageable. Even had a fun glissade down!
