Black diamond Big Sky, MT
Mine Shaft drops 354 vertical feet over 921 feet of skiing, with a steepest pitch of 33° about 490 feet below the top. That's steeper than 77% of the 4,740 black diamond runs we've measured in North America, and the 88th steepest of 290 named runs at Big Sky. It faces northeast.
Facing northeast at an average 23°, Mine Shaft gets about 53% of the winter sun that flat ground at Big Sky does, December through March. That's shadier than 91% of the runs we've measured, and the 30th shadiest named run at Big Sky. Its top sits at 7,950 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.
