Black diamond Big Sky, MT
Comet drops 70 vertical feet over 774 feet of skiing, with a steepest pitch of 26° about 10 feet below the top. That's steeper than 27% of the 4,740 black diamond runs we've measured in North America, and the 161st steepest of 290 named runs at Big Sky. It faces north.
Facing north at an average 5°, Comet gets about 48% of the winter sun that flat ground at Big Sky does, December through March. That's shadier than 94% of the runs we've measured, and the 18th shadiest named run at Big Sky. Its top sits at 9,080 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.
