World's Scariest Ski Slopes

Great Scott, Snowbird, UT

The Ride: A 1,000-vertical-foot obstacle course, this run is pitched at a sickly-steep 40 degrees—and also punctuated with rocky knuckles and outcroppings that have given countless skiers unintentional air. If you catch an edge or visibility is poor, don’t be surprised to find yourself segueing from difficult terrain to no terrain at all.

Insider Trivia: With an annual average snowfall of 500 inches, Snowbird gets some of the thickest dry powder in the West. Of course, that won’t help you much on a near-cliff.
