Black diamond Vail, CO
Ptarmigan Ridge drops 634 vertical feet over 7,148 feet of skiing, with a steepest pitch of 14° about 4,590 feet below the top. That's steeper than 2% of the 4,740 black diamond runs we've measured in North America, and the 184th steepest of 194 named runs at Vail. It faces southeast.
Facing southeast at an average 6°, Ptarmigan Ridge gets about 116% of the winter sun that flat ground at Vail does, December through March. That's sunnier than 84% of the runs we've measured, and the 37th sunniest named run at Vail. Its top sits at 10,980 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.
