Blue Ski Mystic Deer Mountain, SD
Collider drops 172 vertical feet over 688 feet of skiing, with a steepest pitch of 27° about 30 feet below the top. That's steeper than 89% of the 5,615 blue runs we've measured in North America, and the 4th steepest of 52 named runs at Ski Mystic Deer Mountain. It faces east.
Facing east at an average 15°, Collider gets about 116% of the winter sun that flat ground at Ski Mystic Deer Mountain does, December through March. That's sunnier than 84% of the runs we've measured, and the 8th sunniest named run at Ski Mystic Deer Mountain. Its top sits at 6,460 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.
