Black diamond Keystone, CO
The Corral drops 613 vertical feet over 2,327 feet of skiing, with a steepest pitch of 21° about 1,170 feet below the top. That's steeper than 9% of the 4,740 black diamond runs we've measured in North America, and the 107th steepest of 140 named runs at Keystone. It faces southwest.
Facing southwest at an average 15°, The Corral gets about 127% of the winter sun that flat ground at Keystone does, December through March. That's sunnier than 91% of the runs we've measured, and the 20th sunniest named run at Keystone. Its top sits at 12,000 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.
