The K2 is a big mountain -- over 28,000 feet of big. It's the second-tallest mountain on Earth, after the might Mount Everest. As such, it gets a lot of freaks trying to climb it; one out of every four who tries ends up dead. None of this seemed to matter much to Dave Watson, international man of mountains. Watson's already summited Everest twice -- and now he's become the only person to ski the K2's upper slopes.
