Double black Big Sky, MT
2nd Gully drops 711 vertical feet over 1,099 feet of skiing, with a steepest pitch of 48° about 470 feet below the top. That's steeper than 95% of the 2,251 double black runs we've measured in North America, and the 9th steepest of 290 named runs at Big Sky. It faces east.
Facing east at an average 41°, 2nd Gully gets about 74% 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 107th shadiest named run at Big Sky. Its top sits at 10,450 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.
