Blue Purgatory, CO
Joan's Jubilee drops 114 vertical feet over 1,339 feet of skiing, with a steepest pitch of 8° about 510 feet below the top. That's steeper than 2% of the 5,615 blue runs we've measured in North America, and the 90th steepest of 90 named runs at Purgatory. It faces northeast.
Facing northeast at an average 5°, Joan's Jubilee gets about 93% of the winter sun that flat ground at Purgatory does, December through March. That's sunnier than 63% of the runs we've measured, and the 14th sunniest named run at Purgatory. Its top sits at 10,610 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.
