Double black Aspen Mountain, CO
T4 drops 587 vertical feet over 1,075 feet of skiing, with a steepest pitch of 43° about 200 feet below the top. That's steeper than 84% of the 2,251 double black runs we've measured in North America, and the 4th steepest of 139 named runs at Aspen Mountain. It faces northeast.
Facing northeast at an average 33°, T4 gets about 66% of the winter sun that flat ground at Aspen Mountain does, December through March. That's shadier than 77% of the runs we've measured, and the 46th shadiest named run at Aspen Mountain. Its top sits at 9,420 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.
