Double black (extreme) Breckenridge, CO
whiff drops 405 vertical feet over 639 feet of skiing, with a steepest pitch of 47° about 200 feet below the top. That's steeper than 95% of the 2,251 double black runs we've measured in North America, and the 7th steepest of 207 named runs at Breckenridge. It faces northeast.
Facing northeast at an average 40°, whiff gets about 36% of the winter sun that flat ground at Breckenridge does, December through March. That's shadier than 99% of the runs we've measured, and the shadiest named run at Breckenridge. Its top sits at 12,440 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.
