Black diamond Big Sky, MT
Big Tree Cutoff drops 599 vertical feet over 3,225 feet of skiing, with a steepest pitch of 21° about 2,700 feet below the top. That's steeper than 10% of the 4,740 black diamond runs we've measured in North America, and the 221st steepest of 290 named runs at Big Sky. It faces northeast.
Facing northeast at an average 11°, Big Tree Cutoff gets about 67% of the winter sun that flat ground at Big Sky does, December through March. That's shadier than 76% of the runs we've measured, and the 63rd shadiest named run at Big Sky. Its top sits at 8,710 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.
