Black diamond Mission Ridge, WA
Tumwater drops 1,367 vertical feet over 5,688 feet of skiing, with a steepest pitch of 31° about 830 feet below the top. That's steeper than 62% of the 4,740 black diamond runs we've measured in North America, and the 26th steepest of 55 named runs at Mission Ridge. It faces northeast.
Facing northeast at an average 14°, Tumwater gets about 67% of the winter sun that flat ground at Mission Ridge does, December through March. That's shadier than 76% of the runs we've measured, and the 30th shadiest named run at Mission Ridge. Its top sits at 6,780 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.
