Black diamond Crystal Mountain, WA
Spook Hill drops 355 vertical feet over 681 feet of skiing, with a steepest pitch of 40° about 500 feet below the top. That's steeper than 96% of the 4,740 black diamond runs we've measured in North America, and the 31st steepest of 133 named runs at Crystal Mountain. It faces northwest.
Facing northwest at an average 32°, Spook Hill gets about 36% of the winter sun that flat ground at Crystal Mountain does, December through March. That's shadier than 99% of the runs we've measured, and the 7th shadiest named run at Crystal Mountain. Its top sits at 6,240 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.
