Facing northwest at an average 21°, Upper Ptarmigan gets about 65% of the winter sun that flat ground at Attitash does, December through March. That's shadier than 79% of the runs we've measured, and the 23rd shadiest named run at Attitash. Its top sits at 2,020 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.
