Facing north at an average 14°, McCormarck's Maze gets about 74% of the winter sun that flat ground at Purgatory does, December through March. That's shadier than 64% of the runs we've measured, and the 36th shadiest named run at Purgatory. Its top sits at 10,530 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.
