Blue White Pass, WA
Ptarmigan drops 509 vertical feet over 2,754 feet of skiing, with a steepest pitch of 21° about 2,510 feet below the top. That's steeper than 45% of the 5,615 blue runs we've measured in North America, and the 44th steepest of 66 named runs at White Pass. It faces west.
Facing west at an average 11°, Ptarmigan gets about 91% of the winter sun that flat ground at White Pass does, December through March. That's sunnier than 61% of the runs we've measured, and the 9th sunniest named run at White Pass. Its top sits at 5,780 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.
