Marco Siffredi

Marco Siffredi (22 May 1979 – 8 September 2002) was a French snowboarder and mountaineer. Siffredi was the first to descend Mount Everest on a snowboard, completing this feat in 2001 via the Norton Couloir. In 2002, he disappeared after making his second Everest summit, while attempting to snowboard the Hornbein Couloir; his body has never been found.

Life
Siffredi was born in Chamonix, France in 1979 and hailed from a climbing family; his father was a mountain guide, and his older brother Pierre had died in an avalanche in their hometown of Chamonix, France. Originally a skier, Siffredi began snowboarding in 1995. In his early years, Marco Siffredi made several first descents in the Chamonix valley before extending his horizons to bigger peaks. The next year, he made a descent from the Mallory track on the North Face of the Aiguille du Midi, a descent of 1000 m with passages of more than a 50-degree incline. At the end of the season, he made the first snowboard decent of the Chardonnet. In 1998, he headed to Peru where he summited and successful descended Tocllaraju (6,032 m) with Philippe Forte and René Robert.

In June 1999, he made the second-ever descent of the Nant-Blanc face on the Aiguille Verte, and the first ever by snowboard, after Jean-Marc Boivin’s ski descent in 1989. Later that season, he headed to the Himalayas and made the first descent of Dorje Lhakpa by snowboard (6,988 meters). Siffredi's descent of the mountain lasted about 3,000 feet, including areas of 55 degrees in steepness. He completed this feat without the use of supplemental oxygen.

In June 2000, he summitted Bolivia's Huayna Potosi (6,088 meters) and that fall, he summitted and snowboarded his first eight-thousander, Cho Oyu.

First Everest descent
Siffredi reached the summit of Everest, the world's tallest peak on May 23, 2001, with the help of oxygen along with two Sherpas who brought the equipment. He spent an hour at the summit before beginning his descent. He was forced to choose an alternative route to the one he considered the "Holy Grail" of snowboarding, as the Hornbein Couloir did not have enough snow. Instead, he rode down the Norton Couloir back to Advanced Base Camp (ABC) at the foot of the North Col. Then he began the descent down the Norton Couloir of the north face, but after 200 m a fastening strap on his snowboard broke due to the cold. After repairing it with help from a sherpa, Siffredi continued the descent to 6400 m in two hours.

The day before, on May 22, Austrian climber Stefan Gatt reached the summit alone and without using oxygen. He went on a snowboard up to 8600 m along the north wall, but at that altitude he found very hard snow and decided to continue without snowboarding. There were disputes about who would be awarded the first snowboard descent of Everest, as Gatt got out first, but did not use a snowboard for about 1000 m. The site everestnews.com attributed primacy to Siffredi but the site snowboarding.transworld.net recognized merits and demerits to both, so the record was shared.

Second Everest descent
Early in August 2002, Siffredi departed for Nepal, intending to make the first snowboard descent of Everest along the Hornbein Couloir. It was late in the season for summitting Everest, but Siffredi hoped that the passage would have more snow. On August 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 8300 m. On September 8, 2002, Siffredi and the sherpas reached the summit at 2:10 p.m. According to Phurba Tashi, however, Siffredi showed little enthusiasm for the accomplishment, commenting that he was "Tired, tired...too much climbing..." The ascent had taken 13 hours.

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 3 p.m. His sherpa companions lost sight of him periodically. At the North Col, about 1300 m 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 autumn 2001, he climbed Shisha Pangma, Himalayas (8027 m) with the intention of making the entire descent by snowboard, but strong winds prevented the attempt.
