Black diamond Big Sky, MT
Bad Dog Gully drops 368 vertical feet over 1,121 feet of skiing, with a steepest pitch of 40° about 60 feet below the top. That's steeper than 95% of the 4,740 black diamond runs we've measured in North America, and the 49th steepest of 290 named runs at Big Sky. It faces northeast.
Facing northeast at an average 20°, Bad Dog Gully gets about 75% of the winter sun that flat ground at Big Sky does, December through March. That's shadier than 64% of the runs we've measured, and the 110th shadiest named run at Big Sky. Its top sits at 8,550 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.
