Black diamond Discovery, MT
Black Moon drops 624 vertical feet over 2,283 feet of skiing, with a steepest pitch of 29° about 1,020 feet below the top. That's steeper than 53% of the 4,740 black diamond runs we've measured in North America, and the 24th steepest of 62 named runs at Discovery. It faces north.
Facing north at an average 16°, Black Moon gets about 55% of the winter sun that flat ground at Discovery does, December through March. That's shadier than 89% of the runs we've measured, and the 23rd shadiest named run at Discovery. Its top sits at 7,110 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.
