Green Mammoth, CA
Round About drops 378 vertical feet over 2,385 feet of skiing, with a steepest pitch of 25° about 310 feet below the top. That's steeper than 98% of the 3,109 green runs we've measured in North America, and the 71st steepest of 151 named runs at Mammoth. It faces east.
Facing east at an average 9°, Round About gets about 95% of the winter sun that flat ground at Mammoth does, December through March. That's sunnier than 66% of the runs we've measured, and the 30th sunniest named run at Mammoth. Its top sits at 8,950 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.
