Black diamond Big Sky, MT
Moonlight drops 1,117 vertical feet over 2,677 feet of skiing, with a steepest pitch of 34° about 180 feet below the top. That's steeper than 81% of the 4,740 black diamond runs we've measured in North America, and the 84th steepest of 290 named runs at Big Sky. It faces northeast.
Facing northeast at an average 25°, Moonlight gets about 54% of the winter sun that flat ground at Big Sky does, December through March. That's shadier than 90% of the runs we've measured, and the 33rd shadiest named run at Big Sky. Its top sits at 9,690 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.
