Green Pine Mountain, MI
Irvine's Ravine drops 57 vertical feet over 515 feet of skiing, with a steepest pitch of 10° about 10 feet below the top. That's steeper than 22% of the 3,109 green runs we've measured in North America, and the 27th steepest of 33 named runs at Pine Mountain. It faces west.
Facing west at an average 6°, Irvine's Ravine gets about 94% of the winter sun that flat ground at Pine Mountain does, December through March. That's sunnier than 65% of the runs we've measured, and the sunniest named run at Pine Mountain. Its top sits at 1,250 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.
