Numbur Attempt. A Japanese expedition, led by Senkichi Kitaoka, attempted in the pre-monsoon season to climb the northwest ridge of Numbur (6959 meters, 22,832 feet). They got to Camp III at 21,650 feet but found the ridge beyond too knife-edged to continue. This would have been a new route. The team doubts the claims of the 1963 Japanese expedition (as other Numbur climbers have before them); if their doubts are correct, Numbur has never been successfully climbed.
