Cho Oyu. Our expedition of three Belgians and two Nepalis established Base Camp and Camps I and II at 5750, 6400 and 7000 meters on July 31, August 4 and 12. We made the first summit attempt on August 13 and the second on the 18th. The third was successful. Louis Lange and I left Base Camp on August 22 and bivouacked at 7600 meters. We were on the summit at 11:15 on August 23. From 7000 meters we made a more direct ascent to the right of the classic route because the snow was deep and the avalanche danger great. Because of the fine weather, we could climb during much of the night.
