Black diamond Loon Mountain, NH
Undercut drops 787 vertical feet over 2,924 feet of skiing, with a steepest pitch of 28° about 1,330 feet below the top. That's steeper than 41% of the 4,740 black diamond runs we've measured in North America, and the 10th steepest of 76 named runs at Loon Mountain. It faces west.
Facing west at an average 16°, Undercut gets about 102% of the winter sun that flat ground at Loon Mountain does, December through March. That's sunnier than 73% of the runs we've measured, and the 3rd sunniest named run at Loon Mountain. Its top sits at 2,330 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.
