Blue Aspen Mountain, CO
Roch Run drops 505 vertical feet over 1,527 feet of skiing, with a steepest pitch of 33° about 1,170 feet below the top. That's steeper than 99% of the 5,615 blue runs we've measured in North America, and the 69th steepest of 139 named runs at Aspen Mountain. It faces northwest.
Facing northwest at an average 20°, Roch Run gets about 55% of the winter sun that flat ground at Aspen Mountain does, December through March. That's shadier than 89% of the runs we've measured, and the 19th shadiest named run at Aspen Mountain. Its top sits at 9,900 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.
