Double black Aspen Highlands, CO
South Castle drops 1,695 vertical feet over 3,408 feet of skiing, with a steepest pitch of 43° about 1,720 feet below the top. That's steeper than 84% of the 2,251 double black runs we've measured in North America, and the 12th steepest of 104 named runs at Aspen Highlands. It faces east.
Facing east at an average 30°, South Castle gets about 96% of the winter sun that flat ground at Aspen Highlands does, December through March. That's sunnier than 68% of the runs we've measured, and the 19th sunniest named run at Aspen Highlands. Its top sits at 11,570 feet.
With little slope to hide behind, it takes nearly the full winter sun of open ground: powder settles and turns heavy sooner after a storm, and spring snow softens early. Shading from ridges and trees isn't counted yet.
