Blue Buttermilk, CO
Buckskin drops 941 vertical feet over 4,795 feet of skiing, with a steepest pitch of 19° about 610 feet below the top. That's steeper than 36% of the 5,615 blue runs we've measured in North America, and the 21st steepest of 41 named runs at Buttermilk. It faces east.
Facing east at an average 11°, Buckskin gets about 92% of the winter sun that flat ground at Buttermilk does, December through March. That's sunnier than 63% of the runs we've measured, and the 3rd sunniest named run at Buttermilk. Its top sits at 9,330 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.
