Chogolisa is one of the highest mountains of central Karakoram and form an impressive trapezoid comprising 2 summits (North-eastern summit - 7,654m., South-western summit - 7,665m) and 4 ridges. First, Martin Conway explored the area that was very impressive by this white pyramid of snow christened “Bride Peak “(means the wife of K2 just opposite, a pretty couple!). The mortals veils of Chogolisa as unreal whiteness are where disappeared H.Buhl in 1957 on a cornice on the North-eastern ridge around 7,100 m, without rope and blind by a thick fog whereas he climbed the top with K.Diemberger. Climbing Chogolisa is one of the easiest climb of Karakoram, but this tragedy shows that even the best climber’s ones can make big errors. Martin Conway try the first to climb the summit (three times without success), attempts continue in 1909 with Louis Amédée of Savoy, duke of Abruzzi, J.Petigax, H. and A. Brocherel of Courmayeur which make a challenging climb until in 1922: all the difficulties crossed about 7400 m, they turn back in a thick fog at 250 meters down the top.The 4 August, 1958, Japanese K.Hirai &. Fujihira try to reach the top again but didn't go beyond the North-eastern summit (7654m) completing an exploration started in 1892 by Martin Conway. 2 French climbers died in 1986 during a sky descent from the top.The first climb of the South-western top was made by Austrians G.Ammerer and A.Pressl by the Western edge in 1975; the second time , by B.Aucher French, P.Dubois, J.M.Galmiche and E.Monier by the Southern edge in 1984. In 1986, the british L.Elliot, A. Fanshawe, H.Irvine and S.Lamb made the first traverse between the 2 summits, from West to East, and finished by the North-eastern summit.
