Black diamond Big Sky, MT
Bitteroot drops 297 vertical feet over 1,268 feet of skiing, with a steepest pitch of 30° about 280 feet below the top. That's steeper than 56% of the 4,740 black diamond runs we've measured in North America, and the 113th steepest of 290 named runs at Big Sky. It faces southeast.
Facing southeast at an average 14°, Bitteroot gets about 131% of the winter sun that flat ground at Big Sky does, December through March. That's sunnier than 93% of the runs we've measured, and the 45th sunniest named run at Big Sky. Its top sits at 9,000 feet.
Angled toward the low winter sun, it bakes: powder turns heavy soon after a storm, and in spring it softens early in the day and refreezes hard overnight. Shading from ridges and trees isn't counted yet.
