Black diamond Big Sky, MT
Broken Arrow drops 831 vertical feet over 2,488 feet of skiing, with a steepest pitch of 30° about 1,750 feet below the top. That's steeper than 59% of the 4,740 black diamond runs we've measured in North America, and the 107th steepest of 290 named runs at Big Sky. It faces northeast.
Facing northeast at an average 20°, Broken Arrow gets about 64% of the winter sun that flat ground at Big Sky does, December through March. That's shadier than 80% of the runs we've measured, and the 50th shadiest named run at Big Sky. Its top sits at 8,670 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.
