Chogolisa (or Bride Peak) is a mountain in the Karakorum region of Pakistan. It lies near the Baltoro Glacier in the Concordia region which is home to some of the highest peaks of the world. Chogolisa has several peaks; the highest on the SW face (Chogolisa-I) rises to 7,665 meters (25,147 ft).
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 suchmuck 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 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 japanes expedition from the Academic Alpine Club kyoto university led by Takeo Kuwabara made the 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 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.
