Black diamond Breckenridge, CO
Ptarmigan drops 720 vertical feet over 2,175 feet of skiing, with a steepest pitch of 30° about 560 feet below the top. That's steeper than 58% of the 4,740 black diamond runs we've measured in North America, and the 99th steepest of 207 named runs at Breckenridge. It faces northeast.
Facing northeast at an average 19°, Ptarmigan gets about 65% of the winter sun that flat ground at Breckenridge does, December through March. That's shadier than 78% of the runs we've measured, and the 33rd shadiest named run at Breckenridge. Its top sits at 12,080 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.
