Gasherbrum III (ur|گاشر برم۔۳);), surveyed as K3a, is a summit in the Gasherbrum massif of the Baltoro Muztagh, a subrange of the Karakoram on the border between Xinjiang, China and Gilgit-Baltistan, Pakistan.[1] It is situated between Gasherbrum II and IV.
Gasherbrum III fails to meet a topographic prominence cutoff to be an independent mountain; hence it can be considered a subpeak of Gasherbrum II.[2]
Gasherbrum III was one of the highest unclimbed summits in the world[3] up to its first ascent in 1975, by Wanda Rutkiewicz, Alison Chadwick-Onyszkiewicz, Janusz Onyszkiewicz and Krzysztof Zdzitowiecki, members of a Polish expedition.[4]
