Green Mammoth, CA
Lupin drops 945 vertical feet over 5,378 feet of skiing, with a steepest pitch of 23° about 1,860 feet below the top. That's steeper than 96% of the 3,109 green runs we've measured in North America, and the 85th steepest of 151 named runs at Mammoth. It faces east.
Facing east at an average 10°, Lupin gets about 103% of the winter sun that flat ground at Mammoth does, December through March. That's sunnier than 74% of the runs we've measured, and the 16th sunniest named run at Mammoth. Its top sits at 9,060 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.
