Double black Bretton Woods, NH
Boundary Line Glades drops 173 vertical feet over 1,374 feet of skiing, with a steepest pitch of 23° about 680 feet below the top. That's steeper than 9% of the 2,251 double black runs we've measured in North America, and the 29th steepest of 95 named runs at Bretton Woods. It faces east.
Facing east at an average 8°, Boundary Line Glades gets about 91% of the winter sun that flat ground at Bretton Woods does, December through March. That's sunnier than 61% of the runs we've measured, and the 6th sunniest named run at Bretton Woods. Its top sits at 2,730 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.
