In 2004, Sharp joined a Franco-Austrian expedition to the north side of Mount Everest,[11] climbed to 8,500m (27,887ft), but did not reach the summit.[13] Sharp could not keep up with the others and stopped before the First Step.[11] The expedition's leader was Hugues d’Aubarede, a French climber who was later killed in the 2008 K2 disaster (his third attempt to climb that mountain),[14] but who became, on this 2004 expedition, the 56th French person to summit Everest.[14] D'Aubarede's group reached the summit on the morning of 17 May[15] and included Austrians Marcus Noichl, Paul Koller, and Fredrichs "Fritz" Klausner as well as Nepalis Chhang Dawa Sherpa, Lhakpa Gyalzen Sherpa, and Zimba Zangbu Sherpa (also known as Ang Babu).[15][16] When Sharp died in 2006, d'Aubarede was on an expedition to K2.[17]
