Black diamond Mountain High, CA
Calamity drops 491 vertical feet over 1,457 feet of skiing, with a steepest pitch of 27° about 810 feet below the top. That's steeper than 38% of the 4,740 black diamond runs we've measured in North America, and the 10th steepest of 37 named runs at Mountain High. It faces northwest.
Facing northwest at an average 20°, Calamity gets about 70% of the winter sun that flat ground at Mountain High does, December through March. That's shadier than 71% of the runs we've measured, and the 14th shadiest named run at Mountain High. Its top sits at 7,900 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.
