Some of the biggest airs in the history of snowboarding were launched from the 22-foot halfpipe in Vail's Golden Peak Terrain Park in March, when the Burton US Open rolled through. In the men's contest, Shaun White actually soared above the 25-foot measuring stick, executing a lofty backside air that managed to be as impressive as any of the more technical spins farther down in his winning run. In the women's contest, fifteen-year-old Chloe Kim sent her own massive backside air far down the pipe, gathering speed for back-to-back 1080s. Vail's pipe crew kept it in top form for weekend warriors all season, grooming the walls to competition specs every Friday, Saturday and Sunday. Not quite ready to send your own tricks fifty feet above the flat bottom? Try warming up on the smaller pipe — also on Golden Peak, but featuring less-imposing thirteen-foot walls — to build up some confidence.
