For anyone who hasn’t dropped into Jackson Hole’s Corbet’s Couloir, here’s a tip: The first turn is key. After the initial free-fall, you need to take an immediate hard right to avoid a rock face—then it’s a few high-speed GS turns as the chute widens into the spill-out. The run was named after local instructor and guide Barry Corbet, who looked down the chute in 1960 and famously said, “Someday somebody will ski that.” Fifty years later, the run just might be America’s most celebrated test of knees and nerves. To add to the pressure, a tram jammed with vocal critics passes within viewing range every 10 minutes. If that concerns you, you’re not ready.
