Black diamond Bridger Bowl, MT
Ptarmigan drops 779 vertical feet over 1,827 feet of skiing, with a steepest pitch of 34° about 220 feet below the top. That's steeper than 80% of the 4,740 black diamond runs we've measured in North America, and the 7th steepest of 46 named runs at Bridger Bowl. It faces east.
Facing east at an average 25°, Ptarmigan gets about 119% of the winter sun that flat ground at Bridger Bowl does, December through March. That's sunnier than 86% of the runs we've measured, and the 10th sunniest named run at Bridger Bowl. Its top sits at 7,990 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.
