Double black Discovery, MT
Spooky Hollow drops 642 vertical feet over 1,312 feet of skiing, with a steepest pitch of 40° about 560 feet below the top. That's steeper than 70% of the 2,251 double black runs we've measured in North America, and the 4th steepest of 62 named runs at Discovery. It faces north.
Facing north at an average 30°, Spooky Hollow gets about 34% of the winter sun that flat ground at Discovery does, December through March. That's shadier than 99% of the runs we've measured, and the 4th shadiest named run at Discovery. Its top sits at 8,060 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.
