Blue Mammoth, CA
Gremlin's Gulch drops 324 vertical feet over 1,458 feet of skiing, with a steepest pitch of 23° about 1,370 feet below the top. That's steeper than 64% of the 5,615 blue runs we've measured in North America, and the 89th steepest of 151 named runs at Mammoth. It faces west.
Facing west at an average 13°, Gremlin's Gulch gets about 103% of the winter sun that flat ground at Mammoth does, December through March. That's sunnier than 75% of the runs we've measured, and the 14th sunniest named run at Mammoth. Its top sits at 9,890 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.
