Topographic Architecture of Gasherbrum IV
Gasherbrum IV, at 7,925 meters (26,001 ft), is the 17th highest mountain on Earth and the 6th highest in Pakistan. Rising dramatically at the head of the Baltoro Glacier, its breathtaking 2,500-meter West Face of sheer limestone and marble—termed 'The Shining Wall'—is regarded as one of the ultimate technical mountaineering challenges on the planet. First climbed in 1958 by Walter Bonatti and Carlo Mauri via the Northeast Ridge, it later saw the legendary 1985 alpine-style ascent of its West Face by Wojciech Kurtyka and Robert Schauer, widely called the 'Climb of the Century'.
