Black diamond Aspen Highlands, CO
I-70 drops 158 vertical feet over 457 feet of skiing, with a steepest pitch of 30° about 410 feet below the top. That's steeper than 55% of the 4,740 black diamond runs we've measured in North America, and the 59th steepest of 104 named runs at Aspen Highlands. It faces northeast.
Facing northeast at an average 20°, I-70 gets about 73% of the winter sun that flat ground at Aspen Highlands does, December through March. That's shadier than 66% of the runs we've measured, and the 56th shadiest named run at Aspen Highlands. Its top sits at 10,310 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.
