Blue Keystone, CO
Foxtrot drops 332 vertical feet over 3,744 feet of skiing, with a steepest pitch of 12° about 3,710 feet below the top. That's steeper than 5% of the 5,615 blue runs we've measured in North America, and the 138th steepest of 140 named runs at Keystone. It faces south.
Facing south at an average 5°, Foxtrot gets about 131% of the winter sun that flat ground at Keystone does, December through March. That's sunnier than 93% of the runs we've measured, and the 14th sunniest named run at Keystone. Its top sits at 11,440 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.
