Big Tree Chute drops 360 vertical feet over 596 feet of skiing, with a steepest pitch of 42° about 200 feet below the top. That's steeper than 98% of the 4,740 black diamond runs we've measured in North America, and the 43rd steepest of 227 named runs at Crested Butte. It faces northeast.
Facing northeast at an average 37°, Big Tree Chute gets about 40% of the winter sun that flat ground at Crested Butte does, December through March. That's shadier than 97% of the runs we've measured, and the 2nd shadiest named run at Crested Butte. Its top sits at 10,400 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.
