Green Mammoth, CA
Sleepy Hollow drops 551 vertical feet over 4,016 feet of skiing, with a steepest pitch of 15° about 10 feet below the top. That's steeper than 55% of the 3,109 green runs we've measured in North America, and the 133rd steepest of 151 named runs at Mammoth. It faces east.
Facing east at an average 8°, Sleepy Hollow gets about 94% of the winter sun that flat ground at Mammoth does, December through March. That's sunnier than 65% of the runs we've measured, and the 32nd sunniest named run at Mammoth. Its top sits at 8,940 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.
