Double black Aspen Mountain, CO
Corkscrew Gully drops 673 vertical feet over 1,612 feet of skiing, with a steepest pitch of 33° about 1,360 feet below the top. That's steeper than 36% of the 2,251 double black runs we've measured in North America, and the 66th steepest of 139 named runs at Aspen Mountain. It faces north.
Facing north at an average 25°, Corkscrew Gully gets about 44% of the winter sun that flat ground at Aspen Mountain does, December through March. That's shadier than 96% of the runs we've measured, and the 6th shadiest named run at Aspen Mountain. Its top sits at 9,020 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.
