Blue Big Sky, MT
The Nile drops 111 vertical feet over 538 feet of skiing, with a steepest pitch of 19° about 490 feet below the top. That's steeper than 30% of the 5,615 blue runs we've measured in North America, and the 241st steepest of 290 named runs at Big Sky. It faces north.
Facing north at an average 12°, The Nile gets about 65% of the winter sun that flat ground at Big Sky does, December through March. That's shadier than 79% of the runs we've measured, and the 54th shadiest named run at Big Sky. Its top sits at 8,730 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.
