Sumeru Parbat Attempt, South Ridge, 1989. Geoffrey Degens, Alan King, Richard Sullivan and I made the first ascent of the south ridge of Sumeru Parbat (6331 meters, 20,770 feet) in September 1989 but had to quit 400 feet below the summit because of deteriorating weather. It would have been a snow plod from there to the top. The ridge itself was knife-edged with mixed snow and rock.
