Blue Aspen Mountain, CO
Lower Little Nell drops 514 vertical feet over 2,226 feet of skiing, with a steepest pitch of 21° about 30 feet below the top. That's steeper than 49% of the 5,615 blue runs we've measured in North America, and the 128th steepest of 139 named runs at Aspen Mountain. It faces north.
Facing north at an average 13°, Lower Little Nell gets about 70% of the winter sun that flat ground at Aspen Mountain does, December through March. That's shadier than 70% of the runs we've measured, and the 61st shadiest named run at Aspen Mountain. Its top sits at 8,470 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.
