Blue Wolf Creek, CO
Summer Day drops 570 vertical feet over 2,715 feet of skiing, with a steepest pitch of 29° about 490 feet below the top. That's steeper than 95% of the 5,615 blue runs we've measured in North America, and the 66th steepest of 131 named runs at Wolf Creek. It faces east.
Facing east at an average 12°, Summer Day gets about 91% of the winter sun that flat ground at Wolf Creek does, December through March. That's sunnier than 62% of the runs we've measured, and the 39th sunniest named run at Wolf Creek. Its top sits at 11,580 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.
