Double black Purgatory, CO
Sun Dog drops 461 vertical feet over 1,167 feet of skiing, with a steepest pitch of 38° about 340 feet below the top. That's steeper than 61% of the 2,251 double black runs we've measured in North America, and the 4th steepest of 90 named runs at Purgatory. It faces east.
Facing east at an average 24°, Sun Dog gets about 98% of the winter sun that flat ground at Purgatory does, December through March. That's sunnier than 69% of the runs we've measured, and the 10th sunniest named run at Purgatory. Its top sits at 9,310 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.
