Black diamond Aspen Mountain, CO
Sunrise drops 380 vertical feet over 1,052 feet of skiing, with a steepest pitch of 30° about 560 feet below the top. That's steeper than 57% of the 4,740 black diamond runs we've measured in North America, and the 88th steepest of 139 named runs at Aspen Mountain. It faces west.
Facing west at an average 21°, Sunrise gets about 99% of the winter sun that flat ground at Aspen Mountain does, December through March. That's sunnier than 70% of the runs we've measured, and the 6th sunniest named run at Aspen Mountain. Its top sits at 10,560 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.
