Best time for Climbing Chogolisa is from June to September
The first climb on Chogolisa (SW) 7665m 25157ft was made by an Austrian expedition team led by Eduard Koblmuller. Gustav Ammerer and Fred Pressl were the first who reached the summit on August 2, 1975. The team leader Eduard Koblmuller fell through a cornice during climbing, but fortunately, he was roped and team members pull him safely.
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). 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.
