Route Notes Aspen Cho Oyu-Everest Expedition - Spring 2007 The team of three American members and two Sherpas led by Mike Marolt first climbed the northwest side of Cho Oyu and directly from there went to the North Col route on Everest. No oxygen taken, none used. No serious medical problems. Entire team of Mike Marolt, Steve Marolt, Jim Gile, Karma Sherpa and Pemba Norbu left C2 at 9:00 pm (NST) on 4 May. Mike Marolt reported: "We started our climb that climb that day from C2 eliminating the high camp. So by the time we all got up to that final summit plateau, we were very tired. Steve and the Sherpas were a bit ahead and yelled down that the summit was 'go'. Jim (Gile) thought it was a lot farther than it was and interpreterd the 'go' as a 'no'. So he stayed put (at about 8150m). When he realized what had happened, it was too late for him to continue and he was very tired." Steve Marolt and both Sherpas had reached the summit at 11:00 am on 5 May. Mike Marolt turned back at about 8100m because he was sick with bronchitis and could go no higher. The three members skied all the way from their high points back to C1. The team left Cho Oyu base camp on 9 May and went to Tingri to rest before proceeding to Everest. Kari Kobler - 28 May 2007 The three-member team of Mike Marolt, his twin brother Steve, and Jim Gile went first to Cho Oyu and from there directly to Everest. They had two Sherpas with them on Cho Oyu. They arrived at their Cho Oyu BC on 19 April. On about 10 May they went for the summit; Gile and Mike Marolt stopped at 8100m, but Steve went to the summit with Norbu and Karma Sherpas. The three members then skied down the mountain to C1, Steve from the summit and the others from 8100m. They went immediately to Everest and arrived at BC on 14 May. They now had three Sherpas with them: Norbu and Karma from their Cho Oyu climb, and Mingma from Kobler's Everest climb. The Americans moved up the mountain as follows: ABC - 16 May C1 - 17 May, down to ABC on about 18 May C2 - 19 May at 7800m C3 - 20 May at 8300m On 21 May they left C3 for the summit, but they turned back at 8500m. They had climbed without any oxygen; now they were cold and very tired, and they descended to C2. On 22 May the three members skied from C2 to 6600m.
