Double black Powder Mountain, UT
Thunderdome drops 947 vertical feet over 3,310 feet of skiing, with a steepest pitch of 38° about 640 feet below the top. That's steeper than 60% of the 2,251 double black runs we've measured in North America, and the 24th steepest of 204 named runs at Powder Mountain. It faces north.
Facing north at an average 17°, Thunderdome gets about 55% of the winter sun that flat ground at Powder Mountain does, December through March. That's shadier than 89% of the runs we've measured, and the 15th shadiest named run at Powder Mountain. Its top sits at 8,390 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.
