Black diamond Keystone, CO
Foxtrot Glades drops 393 vertical feet over 1,427 feet of skiing, with a steepest pitch of 25° about 180 feet below the top. That's steeper than 22% of the 4,740 black diamond runs we've measured in North America, and the 67th steepest of 140 named runs at Keystone. It faces south.
Facing south at an average 16°, Foxtrot Glades gets about 133% of the winter sun that flat ground at Keystone does, December through March. That's sunnier than 94% of the runs we've measured, and the 8th sunniest named run at Keystone. Its top sits at 11,230 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.
