Blue Aspen Mountain, CO
Upper Little Nell drops 215 vertical feet over 667 feet of skiing, with a steepest pitch of 24° about 560 feet below the top. That's steeper than 68% of the 5,615 blue runs we've measured in North America, and the 118th steepest of 139 named runs at Aspen Mountain. It faces north.
Facing north at an average 19°, Upper Little Nell gets about 57% of the winter sun that flat ground at Aspen Mountain does, December through March. That's shadier than 88% of the runs we've measured, and the 25th shadiest named run at Aspen Mountain. Its top sits at 8,690 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.
