Blue Breckenridge, CO
union drops 436 vertical feet over 3,863 feet of skiing, with a steepest pitch of 20° about 2,700 feet below the top. That's steeper than 40% of the 5,615 blue runs we've measured in North America, and the 160th steepest of 207 named runs at Breckenridge. It faces north.
Facing north at an average 7°, union gets about 67% of the winter sun that flat ground at Breckenridge does, December through March. That's shadier than 76% of the runs we've measured, and the 35th shadiest named run at Breckenridge. Its top sits at 11,600 feet.
Shaded snow stays colder and drier, so it holds powder longer after a storm and is slower to crust over or turn to slush in spring. Shading from ridges and trees isn't counted yet.
