Blue Mammoth, CA
X-Course drops 393 vertical feet over 2,621 feet of skiing, with a steepest pitch of 18° about 310 feet below the top. That's steeper than 26% of the 5,615 blue runs we've measured in North America, and the 119th steepest of 151 named runs at Mammoth. It faces northeast.
Facing northeast at an average 9°, X-Course gets about 83% of the winter sun that flat ground at Mammoth does, December through March. That's shadier than 50% of the runs we've measured, and the 113th shadiest named run at Mammoth. Its top sits at 9,120 feet.
It gets an ordinary dose of sun: powder lasts a typical amount of time, and spring snow softens on a normal schedule. Shading from ridges and trees isn't counted yet.
