Cho Oyu Attempt. On April 9, Australian Bill Harkin and I arrived at Tingri. Difficulties with yak drivers and moraine snow drifts prevented our establishing Base Camp at 5700 meters until the 27th. We attempted the northwest-face route with camps at 6850,7200 and 7580 meters. Our route differed from the standard one from 7200 meters on as we tried to gain the summit snowfield from the extreme western edge of the face. Our first summit attempt failed in high winds and with a broken crampon. I made a second solo summit try from May 10 to 13 but ended it to try to rescue Stefan Wörner. (See above.)
