Cho Oyu Attempt. On October 13, Dan Langmade and I arrived at the Cho Oyu Base Camp at 5700 meters to attempt the standard route. We set up Camps I, II and III at 6850, 7200 and 7650 meters on October 14, 15 and 16. On October 17 we climbed to 7800 meters but turned back because of high winds and cold. We hoped for another attempt on the 18th, but high winds destroyed our tent in the night and we retreated to Base Camp. There was no time for a second attempt.
