It is the third-highest peak of the Gasherbrum massif, and is located in the Karakoram, on the border between Gilgit–Baltistan, Pakistan, and Xinjiang, China. The mountain was first climbed on July 7, 1956, by an Austrian expedition which included Fritz Moravec, Josef Larch, and Hans Willenpart. Gasherbrum II is located on the border of Gilgit–Baltistan, Pakistan, and Xinjiang, China. It is part of the Karakoram mountain range in the Himalayas, and located at the top of the Baltoro Glacier.
With an elevation of 8,034 metres (26,358 ft) it is the third-highest member of the Gasherbrum group, behind Gasherbrum I (8,080 metres or 26,510 feet) and Broad Peak (8,051 metres or 26,414 feet). Gasherbrum III is sometimes considered to be a subpeak of Gasherbrum II, because the former has a topographic prominence of only 461 metres (1,512 ft).
