Black diamond Aspen Mountain, CO
Blondie's drops 406 vertical feet over 1,808 feet of skiing, with a steepest pitch of 28° about 540 feet below the top. That's steeper than 40% of the 4,740 black diamond runs we've measured in North America, and the 102nd steepest of 139 named runs at Aspen Mountain. It faces north.
Facing north at an average 13°, Blondie's gets about 66% of the winter sun that flat ground at Aspen Mountain does, December through March. That's shadier than 78% of the runs we've measured, and the 44th shadiest named run at Aspen Mountain. Its top sits at 10,710 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.
