Peaks near Pasu. Although the weather was not particularly good, we did climb some lovely 5000ers. On June 13, Robert Gruber ascended solo Sost Sar (c. 5200 meters, 17,061 feet) by its rocky south face. The peak lies north of Sost, a village just east of the junction of the Khunjerab and Chapsuran Rivers. On June 16, Gruber and I climbed Khudabad Sar (5230 meters, 17,159 feet) by its northwest side. The next day we ascended the next peak to the west, Borumter Sar (5480 meters, 17,979 feet) by its 60° east face. The two peaks lie at the head of the next valley west of the Kar Purar valley. On July 17, Christine Schmid, Gruber and I made the first ascent of Ambarin Sar (6175 meters, 20,260 feet). We traveled for three days from Pasu up the Shimshal valley to Ambarin Base Camp. We camped at 5000 meters on the ascent and at 5800 meters on the descent of the south ridge. The peak lies south of the village of Zyara and east of the Momhil Glacier.
