Chogolisa (Urdu: چوگولیزا derived from Chogo Ling Sa; literally "Great Hunt") is a trapezoidal mountain located in the Karakoram range within the Gilgit-Baltistan region of Pakistan. It is situated near the Baltoro Glacier in the Concordia region, which is renowned for hosting some of the world's tallest peaks.
Chogolisa has several peaks: The highest peak, found on its southwest face (Chogolisa I), reaches an elevation of 7,665 meters (25,148 feet). On the northeast side, the second-highest peak stands at 7,654 meters in height and was named "Bride Peak" by Martin Conway in 1892.
In 1909, a party led by Duke of the Abruzzi reached 7,498 m (24,600 ft) from a base camp located on the northern side and a high camp on the Chogolisa saddle at 6,335 m. Bad weather stopped the party from ascending further, but their climb established a new world altitude record.
Austrian mountaineers Hermann Buhl and Kurt Diemberger attempted Chogolisa in 1957 after they had successfully summitted Broad Peak behind Marcus Schmuck and Fritz Wintersteller a few weeks earlier. On June 25, they left camp I and camped in a saddle at 6,706 m on the southeast ridge. On June 27, a sudden snowstorm forced them to retreat less than 2000ft from the summit and, on the descent, Buhl broke off a big cornice and fell into the mountain's near vertical north face. His body has never been found.
On August 4, 1958, a Japanese expedition from the Academic Alpine Club Kyoto University led by Takeo Kuwabara (桑原武夫) made the first ascent of Chogolisa II, placing Masao Fujihira and Kazumasa Hirai on top.
The first ascent of Chogolisa I was made on August 2, 1975, by Fred Pressl and Gustav Ammerer of an Austrian expedition led by Eduard Koblmueller. Koblmueller almost suffered the same fate as Buhl, as he also fell through a snow cornice on the ascent, but he was roped and team members were able to pull him to safety.
