Double black Big Sky, MT
Hellroaring drops 1,028 vertical feet over 1,729 feet of skiing, with a steepest pitch of 44° about 890 feet below the top. That's steeper than 87% of the 2,251 double black runs we've measured in North America, and the 24th steepest of 290 named runs at Big Sky. It faces north.
Facing north at an average 37°, Hellroaring gets about 28% of the winter sun that flat ground at Big Sky does, December through March. That's shadier than 100% of the runs we've measured, and the shadiest named run at Big Sky. Its top sits at 10,000 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.
