Passu Sar

Passu Sar is a mountain peak in the Batura Muztagh, a sub-range of the Karakoram mountain range, in the Hunza District of Gilgit-Baltistan, Pakistan. It is the high point of the Passu massif, which also includes Passu Diar. The peak lies on the main ridge of the Batura Muztagh, about east of Batura Sar.
The date of the first successful ascent of Passu Sar is disputed. It was said to have been first climbed in 1978 by a Japanese-Pakistani team, in an expedition which claimed the life of Japanese climber Toshio Takahashi, who fell into a crevasse at 5,800 meters. Another report dates the first ascent on 7 August 1994 by the German team of Max Wallner, Dirk Naumann, Ralf Lehmann, and Volker Wurnig.
