10, he left Kathmandu with three sherpa (Phurba, Pa Nuru and Da Tenzing), reaching base camp in Tibet on August 14. On September 7, the group reached the advanced field at 8,300 m. On Sept. 8, 2002, Siffredi and the sherpas reached the summit at 2:10 PM. According to Phurba Tashi, however, Siffredi showed little enthusiasm for the accomplishment, commenting that he was "Tired, tired...too much climbing..." After weather conditions began to change, the Sherpas urged Siffredi not to go. Siffredi ignored their warnings and after an hour's rest, began making his way towards the Hornbein just after 3pm. His sherpa companions lost sight of him periodically. At the North Col, about 1,300 meters below Camp Three, both Sherpas reported seeing the distant image of a man stand up, then slide silently down the mountain. As they reached the point of the sighting, Siffredi's snowboard tracks were not to be seen. His body has not been found. Other achievements In May 1996, Siffredi snowboarded down the north face of the Aiguille du Midi on Mont Blanc along the Mallory track, a descent of 1,000 meters with passages of more than 50-degree incline. In 1998, in preparation for climbing the Himalayas, he climbed Tocllaraju in Peru (6,032 m) with Philippe Forte and René Robert. In 1999 he climbed Dorje Lhakpa (6,988 m) in Nepal and made the first snowboard descent of the mountain. In autumn 2001, he climbed Shisha Pangma, Himalayas (8,027 m) with the intention of making the entire descent by snowboard, but strong winds prevented the attempt.
