as "arguably the most notable mountaineering achievement during the entire 2001 season." A third ascent by a new line on the peak's South Face was made by Americans Kyle Dempster and Hayden Kennedy on August 21, 2012. Compatriot Josh Wharton had also accompanied them on the climb but had to abandon the attempt at approximately 6800 meters (approximately 22,310 feet) due to altitude sickness. Earlier in their trip the two had made another first ascent (along with Slovenian Urban Novak) of a new line on the massive east face of K7 (6,934 meters, 22,749 feet).
