Double black Big Sky, MT
Big Rock Tongue drops 834 vertical feet over 2,070 feet of skiing, with a steepest pitch of 41° about 560 feet below the top. That's steeper than 76% of the 2,251 double black runs we've measured in North America, and the 36th steepest of 290 named runs at Big Sky. It faces east.
Facing east at an average 24°, Big Rock Tongue gets about 76% of the winter sun that flat ground at Big Sky does, December through March. That's shadier than 61% of the runs we've measured, and the 115th shadiest named run at Big Sky. Its top sits at 9,270 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.
