Black diamond Vail, CO
O.S. drops 807 vertical feet over 2,732 feet of skiing, with a steepest pitch of 33° about 830 feet below the top. That's steeper than 74% of the 4,740 black diamond runs we've measured in North America, and the 26th steepest of 194 named runs at Vail. It faces southeast.
Facing southeast at an average 17°, O.S. gets about 115% 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 40th sunniest named run at Vail. Its top sits at 10,350 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.
