You could say Greg Hill is a numbers guy. The Canadian ski mountaineer has clocked 50,000 feet of vertical in 24 hours, 80 10,000-foot days in one season, a million vertical feet in one season, and skied the 21 summits of the Monashee Mountains in 21 days. Now, using his multiplication skills and mind-boggling aerobic endurance, Hill is in the midst of an attempt to climb and ski two million vertical feet in a calendar year, averaging 5,500 feet a day, every day. For you visual learners, that's the equivalent of 36 trips up and down Mt. Everest. Greg will document his quest (read: have to haul a five-pound HD camera) with blog updates and video trip reports as he travels between hemispheres with the winter, seeking two million feet worth of steep skin tracks and deep pow turns.
