Senn spent night of 25 Oct a little above C2. Max to C2 and informed others they needed help - reached C2 9:00-10 pm. No one knows which person slipped and fell. Accident [on 27 Oct] happened at easy part after bottom end of ridge. None except Senn fell short distance in couloir and her crampons wounded Wettstein's frostbite: very little loss of toes and more of finger. Khadga, Tourism - 28 Oct 83 Mrs Maya Senn and Max Wettstein are seriously injured and helicopter requested in report yesterday. Mrs Senn died according to report today. Helicopter this afternoon went for Wettstein, met expedition representative below BC when Wettstein was not there, pilot instructed them to bring to same spot tomorrow morning. Press Release Climbing a difficult route on the north ridge of their 6812m mountain, which is near Mount Everest, four members reached the summit on Oct 22. They included the expedition's climbing leader, Hans Berger, 35, from Davos-Frauenkirch, Switzerland. Wettstein managed to return to the team's highest camp at about 6200m at nearly 10 o'clock that night to tell others about their weak condition and need for help. But Miss Senn spent the night alone a little distance above the camp and its shelter. Both had frostbite and Wettstein slight head wounds from a minor accidents when Miss Senn fell on him and the steel spikes fitted to her boots cut him. It was during their descent on Oct 27, the day after they had attempted to go to the summit, when Miss Senn was being helped down the mountain side by Bumann, that these two, who were roped together, fell, killing Miss Senn outright and so injuring Bumann so that he died a day later at BC. Wettstein was not involved in this fall, but his condition required helicopter evacuation to KTM. Supersaxo came with him and said last night that Wettstein is not really seriously ill, although he is staying in hospital here for a few days. The other surviving members are expected to return here on Nov 2 after having buried their two teammates bodies near base camp. |
