Green Ski Mystic Deer Mountain, SD
Tunnel drops 31 vertical feet over 147 feet of skiing, with a steepest pitch of 20° about 60 feet below the top. That's steeper than 86% of the 3,109 green runs we've measured in North America, and the 24th steepest of 52 named runs at Ski Mystic Deer Mountain. It faces east.
Facing east at an average 14°, Tunnel gets about 101% of the winter sun that flat ground at Ski Mystic Deer Mountain does, December through March. That's sunnier than 73% of the runs we've measured, and the 17th sunniest named run at Ski Mystic Deer Mountain. Its top sits at 6,440 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.
