Black diamond Mammoth, CA
China Bowl drops 194 vertical feet over 623 feet of skiing, with a steepest pitch of 21° about 350 feet below the top. That's steeper than 9% of the 4,740 black diamond runs we've measured in North America, and the 101st steepest of 151 named runs at Mammoth. It faces northeast.
Facing northeast at an average 18°, China Bowl gets about 73% of the winter sun that flat ground at Mammoth does, December through March. That's shadier than 66% of the runs we've measured, and the 71st shadiest named run at Mammoth. Its top sits at 9,920 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.
