Tukuche, Ascent and Attempts. It was reported that three teams attempted Tukuche (6920m) in the pre-monsoon. Bart Vos (NL) made the first ascent when he climbed the northwest ridge from the French Pass on April 10. Dutch climber Aad Buijtendijk and partner relied heavily on Sherpa support later in the season but were able to reach only 6300 meters by May 1. A ten-member Australian team attempting the same line reached the south summit on May 3 but were unable to progress farther. (High Mountain Sports 179)
