Yuichiro Miura became the first man to ski down Everest in the 1970s. He descended nearly 4,200 vertical feet from the South Col before falling with extreme injuries. Stefan Gatt and Marco Siffredi snowboarded Mount Everest in 2001. Other Everest skiers include Davo Karničar of Slovenia, who completed a top to south base camp descent in 2000, Hans Kammerlander of Italy in 1996 on the north side, and Kit DesLauriers of the United States in 2006. In 2006 Swede Tomas Olsson and Norwegian Tormod Granheim skied together down the north face. Olsson's anchor broke while they were rappelling down a cliff in the Norton couloir at about 8,500 metres, resulting in his death from a two and a half-kilometre fall. Granheim skied down to camp III. Also, Marco Siffredi died in 2002 on his second snow-boarding expedition.
