Black diamond Whitefish, MT
Ptarmigan Bowl drops 548 vertical feet over 1,591 feet of skiing, with a steepest pitch of 28° about 540 feet below the top. That's steeper than 46% of the 4,740 black diamond runs we've measured in North America, and the 49th steepest of 107 named runs at Whitefish. It faces southwest.
Facing southwest at an average 21°, Ptarmigan Bowl gets about 141% of the winter sun that flat ground at Whitefish does, December through March. That's sunnier than 96% of the runs we've measured, and the 25th sunniest named run at Whitefish. Its top sits at 6,660 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.
