Black diamond Aspen Mountain, CO
Summit drops 355 vertical feet over 959 feet of skiing, with a steepest pitch of 30° about 130 feet below the top. That's steeper than 56% of the 4,740 black diamond runs we've measured in North America, and the 90th steepest of 139 named runs at Aspen Mountain. It faces north.
Facing north at an average 22°, Summit 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 7th shadiest named run at Aspen Mountain. Its top sits at 11,040 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.
