Muztagh Tower (Urdu: {{nq|مز تاغ ٹاور), also Mustagh Tower; Muztagh: icy mountain), is a mountain situated in Baltoro Muztagh, which is a segment of the Karakoram range. It straddles the border of the Gilgit–Baltistan region of Pakistan and the Xinjiang Uyghur Autonomous Region of China. Muztagh Tower is located between the basins of the Baltoro and Sarpo Laggo glaciers.[2]
The Mustagh Tower gained attention through a photograph captured by Vittorio Sella during the 1909 Italian expedition to K2. The picture was taken from the upper Baltoro, from a vantage point located due southeast of the mountain. In this photograph, the twin summits of Mustagh Tower appeared perfectly aligned, giving the mountain the appearance of a slender tooth and making it seem extremely impregnable. This image was featured in a book on mountaineering in 1941 with the caption "The Last Citadel".[3]
Nearly five decades after Vittorio Sella's photograph was taken, in 1956, his image served as inspiration for two separate expeditions that raced to achieve the first ascent of Mustagh Tower. Interestingly, both teams discovered that the mountain's routes were less steep than what Sella's photograph had suggested.[4] The British expedition, consisting of John Hartog, Joe Brown, Tom Patey and Ian McNaught-Davis, approached the peak from the Chagaran Glacier on the west side and successfully reached the summit via the Northwest Ridge on July 6.[5] [6] They achieved this feat five days ahead of the French team, consisting of Guido Magnone, fr:Robert Paragot, André Contamine, and Paul Keller, who climbed the mountain from the east.[7] François Florence waited for the two parties at the camp IV during 42 hours without a radio, when they went, reached the summit and came back to this camp.[8]
A lower summit, 7180-1NaN-1 was first climbed in 1984 by the northeast ridge.
