Black diamond Breckenridge, CO
Upper 4 O'Clock drops 691 vertical feet over 2,906 feet of skiing, with a steepest pitch of 25° about 640 feet below the top. That's steeper than 23% of the 4,740 black diamond runs we've measured in North America, and the 133rd steepest of 207 named runs at Breckenridge. It faces east.
Facing east at an average 14°, Upper 4 O'Clock gets about 104% of the winter sun that flat ground at Breckenridge does, December through March. That's sunnier than 76% of the runs we've measured, and the 47th sunniest named run at Breckenridge. Its top sits at 11,940 feet.
With little slope to hide behind, it takes nearly the full winter sun of open ground: powder settles and turns heavy sooner after a storm, and spring snow softens early. Shading from ridges and trees isn't counted yet.
