Keystone offers something few other resorts do: extensive night skiing. Want to take a morning (or afternoon) off? Lift tickets start at 8:30 am, noon, 2, 4 and 6 pm, and are good until Keystone closes at 9.
Little Cottonwood Canyon, home of Alta and Snowbird, is the motherland of American powder skiing. The upper reaches of this Wasatch box canyon regularly get 500 or so inches of the finest fluff in the country.
