Blue Aspen Mountain, CO
Lower Corkscrew drops 140 vertical feet over 337 feet of skiing, with a steepest pitch of 32° about 220 feet below the top. That's steeper than 98% of the 5,615 blue runs we've measured in North America, and the 75th steepest of 139 named runs at Aspen Mountain. It faces north.
Facing north at an average 25°, Lower Corkscrew gets about 49% of the winter sun that flat ground at Aspen Mountain does, December through March. That's shadier than 94% of the runs we've measured, and the 12th shadiest named run at Aspen Mountain. Its top sits at 8,350 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.
