Trango Attempts. Two Japanese expeditions both failed to climb the easternmost of the Trango Towers (5753 meters, 18,875 feet) by its southwest buttress. The first party, led by Yoshimitsu Takatori, in June got to about 1000 feet from the summit. Other climbers of the group climbed Karphogang (5931 meters, 19,460 feet). In September, the two-man party, Hiroshi Aota and Toshiyuki Kikuchu, had hoped to try the same route, but they were prevented by new snow from climbing high.
