Black diamond Aspen Mountain, CO
Dispy Headwall drops 182 vertical feet over 464 feet of skiing, with a steepest pitch of 28° about 60 feet below the top. That's steeper than 40% of the 4,740 black diamond runs we've measured in North America, and the 102nd steepest of 139 named runs at Aspen Mountain. It faces north.
Facing north at an average 23°, Dispy Headwall gets about 45% 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 8th shadiest named run at Aspen Mountain. Its top sits at 11,050 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.
