In 1938, the first man to ever climb Eiger—a 13,025 foot mountain in the Swiss Alps—did so after three days. So when Ueli Steck managed to scale the same peak in under three hours (2 hours, 47 minutes and 33 seconds, to be exact), people were flabbergasted. After watching this video of Steck's feat, you'll be flabbergasted, too. [via kottke.org]
