Thalay Sagar Attempts and Tragedy. A 3-man Japanese expedition led by Kenji Takagi failed to climb Thalay Sagar by its north face. After they had reached 6400 meters in late September, the leader fell to his death from the high point while rappelling. Another Japanese expedition of six were to attempt the first-ascent route via the northeast couloir but they quit after three were non-fatally avalanched on an acclimatization climb on Bhrigupanth.
