Black diamond Gunstock, NH
Birch Glades drops 172 vertical feet over 860 feet of skiing, with a steepest pitch of 19° about 470 feet below the top. That's steeper than 5% of the 4,740 black diamond runs we've measured in North America, and the 26th steepest of 51 named runs at Gunstock. It faces northeast.
Facing northeast at an average 12°, Birch Glades gets about 74% of the winter sun that flat ground at Gunstock does, December through March. That's shadier than 65% of the runs we've measured, and the 14th shadiest named run at Gunstock. Its top sits at 2,070 feet.
Shaded snow stays colder and drier, so it holds powder longer after a storm and is slower to crust over or turn to slush in spring. Shading from ridges and trees isn't counted yet.
