Double black Big Sky, MT
Rock Pocket drops 405 vertical feet over 940 feet of skiing, with a steepest pitch of 45° about 460 feet below the top. That's steeper than 90% of the 2,251 double black runs we've measured in North America, and the 21st steepest of 290 named runs at Big Sky. It faces northeast.
Facing northeast at an average 26°, Rock Pocket gets about 66% of the winter sun that flat ground at Big Sky does, December through March. That's shadier than 78% of the runs we've measured, and the 57th shadiest named run at Big Sky. Its top sits at 8,090 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.
