Facing north at an average 16°, Middle Ptarmigan gets about 59% of the winter sun that flat ground at Attitash does, December through March. That's shadier than 85% of the runs we've measured, and the 11th shadiest named run at Attitash. Its top sits at 1,500 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.
