Torre de Cristal, South Face. The Japanese Saburo Mizobuchi, Tetsuo Nagashino and Moritaka Yoda climbed a fine new route on the Torre de Cristal (18,140 feet), reaching the summit on July 25, 1976. They fixed rope on the lower 800 feet of the south face on mixed rock and ice for two days and then climbed the upper 1000 feet of a very steep ice couloir directly below the summit on the final day.
