Green Purgatory, CO
Lower Demon drops 374 vertical feet over 1,693 feet of skiing, with a steepest pitch of 22° about 100 feet below the top. That's steeper than 92% of the 3,109 green runs we've measured in North America, and the 71st steepest of 90 named runs at Purgatory. It faces east.
Facing east at an average 13°, Lower Demon 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 9th sunniest named run at Purgatory. Its top sits at 9,330 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.
