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). The second highest at 7,654 meters on the NE side (Chogolisa-II) is the one named Bride Peak by Martin Conway in 1892.

In 1909, a party led by Duke of the Abruzzi reached 7,498m from a base camp located on the northern side and a high camp on the Chogolisa saddle at 6,335m. Bad weather stopped the party from ascending further.

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 6,706m on the SW ridge. Bad weather forced them to retreat and on June 27, Buhl fell through a cornice and disappeared. His body has never been found.
In 1958, a Japanese expedition from Kyoto University led by T. Kawabara made the first ascent of Chogolisa-II, placing M. Fujihira and K. 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 Koblmuller. Koblmuller almost suffered the same fate as Buhl, as he also fell through a cornice on the ascent; fortunately, he was roped and team members were able to pull him to safety
