Blue Big Sky, MT
Congo drops 437 vertical feet over 1,218 feet of skiing, with a steepest pitch of 26° about 940 feet below the top. That's steeper than 81% of the 5,615 blue runs we've measured in North America, and the 159th steepest of 290 named runs at Big Sky. It faces northwest.
Facing northwest at an average 21°, Congo gets about 61% of the winter sun that flat ground at Big Sky does, December through March. That's shadier than 84% of the runs we've measured, and the 40th shadiest named run at Big Sky. Its top sits at 8,530 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.
