Green Sunday River, ME
Borealis drops 111 vertical feet over 1,506 feet of skiing, with a steepest pitch of 13° about 230 feet below the top. That's steeper than 43% of the 3,109 green runs we've measured in North America, and the 111th steepest of 126 named runs at Sunday River. It faces east.
Facing east at an average 5°, Borealis gets about 98% of the winter sun that flat ground at Sunday River does, December through March. That's sunnier than 70% of the runs we've measured, and the 14th sunniest named run at Sunday River. Its top sits at 2,760 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.
