Route Notes	Giroud - 30 May 64 Not to summit of Dorje Lhakpa because bad weather by long ridge and very difficult one at 5100m right to top nearly 7000m. 6300m highest point reached 10 May because of snow. Then to Gangchempo nearly 6400m where Darbellay and Rey went to 100m of top on Sat 16, but not to top because too difficult: steepness and on final ridge straight up and had not necessary equipment. Made camp at 5700m.
