Don Sharaf has the run the gauntlet of a 30-year career on snow. He's a co-owner of American Avalanche Institute and has taught avalanche and mountaineering courses for the past 25 years. He's also worked as a heli-ski guide and avalanche forecaster in Alaska for more than a decade. In other words, he's got enough mileage in the mountains to have learned a thing or two, including the profound value of humility when staring into the face of the dragon.
