Blue Breckenridge, CO
Lost Horizon drops 747 vertical feet over 6,435 feet of skiing, with a steepest pitch of 23° about 4,920 feet below the top. That's steeper than 62% of the 5,615 blue runs we've measured in North America, and the 144th steepest of 207 named runs at Breckenridge. It faces east.
Facing east at an average 7°, Lost Horizon gets about 95% of the winter sun that flat ground at Breckenridge does, December through March. That's sunnier than 66% of the runs we've measured, and the 72nd sunniest named run at Breckenridge. Its top sits at 10,750 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.
