Double black Aspen Highlands, CO
Y-12 drops 872 vertical feet over 1,850 feet of skiing, with a steepest pitch of 42° about 400 feet below the top. That's steeper than 80% of the 2,251 double black runs we've measured in North America, and the 17th steepest of 104 named runs at Aspen Highlands. It faces southeast.
Facing southeast at an average 29°, Y-12 gets about 125% of the winter sun that flat ground at Aspen Highlands does, December through March. That's sunnier than 90% of the runs we've measured, and the 2nd sunniest named run at Aspen Highlands. Its top sits at 11,680 feet.
Angled toward the low winter sun, it bakes: powder turns heavy soon after a storm, and in spring it softens early in the day and refreezes hard overnight. Shading from ridges and trees isn't counted yet.
