Austrian mountaineer Herman Buhl accomplished one of the most insane feats in the history of mountaineering when he made the first ascent of this killer mountain solo and without bottled oxygen in 1953. On the way back from the summit he was forced to stand erect on a rock ledge for the entire night at 8,000m altitude in order to survive until the following morning and continue his descent. Before Buhl's success, at least 31 climbers had died on this peak.
