Black diamond Ski Mystic Deer Mountain, SD
Diamond's Edge drops 280 vertical feet over 1,196 feet of skiing, with a steepest pitch of 23° about 730 feet below the top. That's steeper than 16% of the 4,740 black diamond runs we've measured in North America, and the 16th steepest of 52 named runs at Ski Mystic Deer Mountain. It faces west.
Facing west at an average 14°, Diamond's Edge gets about 96% of the winter sun that flat ground at Ski Mystic Deer Mountain does, December through March. That's sunnier than 67% of the runs we've measured, and the 22nd sunniest named run at Ski Mystic Deer Mountain. Its top sits at 6,500 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.
