Double black Big Sky, MT
3rd Gully drops 754 vertical feet over 1,160 feet of skiing, with a steepest pitch of 46° about 510 feet below the top. That's steeper than 93% of the 2,251 double black runs we've measured in North America, and the 13th steepest of 290 named runs at Big Sky. It faces northeast.
Facing northeast at an average 41°, 3rd Gully gets about 70% of the winter sun that flat ground at Big Sky does, December through March. That's shadier than 71% of the runs we've measured, and the 76th shadiest named run at Big Sky. Its top sits at 10,480 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.
