Double black Big Sky, MT
Outer Limits drops 207 vertical feet over 410 feet of skiing, with a steepest pitch of 41° about 90 feet below the top. That's steeper than 75% of the 2,251 double black runs we've measured in North America, and the 38th steepest of 290 named runs at Big Sky. It faces north.
Facing north at an average 31°, Outer Limits gets about 41% of the winter sun that flat ground at Big Sky does, December through March. That's shadier than 97% of the runs we've measured, and the 12th shadiest named run at Big Sky. Its top sits at 9,080 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.
