Double black Mammoth, CA
Dragons Back drops 606 vertical feet over 1,060 feet of skiing, with a steepest pitch of 50° about 70 feet below the top. That's steeper than 99% of the 2,251 double black runs we've measured in North America, and the 1st steepest of 151 named runs at Mammoth. It faces northeast.
Facing northeast at an average 35°, Dragons Back gets about 62% of the winter sun that flat ground at Mammoth does, December through March. That's shadier than 82% of the runs we've measured, and the 40th shadiest named run at Mammoth. Its top sits at 10,570 feet.
Shaded snow stays colder and drier, so it holds powder longer after a storm and is slower to crust over or turn to slush in spring. Shading from ridges and trees isn't counted yet.
