Gasherbrum I
2001 was undoubtedly one of the most important years of his career: in only five months he climbed four 8,000 meters peaks: Everest, Gasherbrum I, Gasherbrum II and Dhaulagiri. On 25 July 2004 he reached the peak of K2 (8611 m) and declared the success of the "K2 2004–50 years later" expedition.
