Excelsior: Record of the international expedition to climb Kangchenjunga in 1930. The German-Austrian-British expedition, led by Günter Oskar Dyhrenfurth, had come from the Nepalese side and tried to reach the North Ridge via its NW face after failing in the north face, where the sherpa Chettan was killed in an avalanche. The attempt failed but the team made the first ascents of Rathong (6678m) and Jongsong Peak (7483m), and also climbed the Southwest peak of Nepal Peak.
