Blue Big Sky, MT
Congo Line drops 251 vertical feet over 969 feet of skiing, with a steepest pitch of 23° about 80 feet below the top. That's steeper than 64% of the 5,615 blue runs we've measured in North America, and the 194th steepest of 290 named runs at Big Sky. It faces northwest.
Facing northwest at an average 15°, Congo Line gets about 71% of the winter sun that flat ground at Big Sky does, December through March. That's shadier than 69% of the runs we've measured, and the 85th 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.
