Black diamond Mountain High, CA
Headwall drops 309 vertical feet over 727 feet of skiing, with a steepest pitch of 28° about 310 feet below the top. That's steeper than 46% of the 4,740 black diamond runs we've measured in North America, and the 8th steepest of 37 named runs at Mountain High. It faces north.
Facing north at an average 25°, Headwall gets about 50% of the winter sun that flat ground at Mountain High does, December through March. That's shadier than 93% of the runs we've measured, and the shadiest named run at Mountain High. Its top sits at 7,460 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.
