John is one of two 19-year-olds on this year's Skiing 100 list. Which explains the photo: This kid takes some serious air¿360's, tip grabs, cross grabs, rodeo flips, switch takeoffs and landings. You could mistake him for some unemployed terrain-park rat, but John is an accomplished instructor, often speaking calmly and directly to his kids' classes while carving perfect turns¿backward. Off the hill, John's a fanatical sea kayaker, mountain biker, and rock climber, and he plays a mean didgeridoo ("Dogs hate it," he says). This fall, John plans to move to Durango, Colorado, to pursue a degree in outdoor education. Expect to find him teaching classes and hucking carcass at Purgatory or Telluride.
