Double black Aspen Mountain, CO
S1 drops 690 vertical feet over 1,307 feet of skiing, with a steepest pitch of 44° about 140 feet below the top. That's steeper than 88% of the 2,251 double black runs we've measured in North America, and the 2nd steepest of 139 named runs at Aspen Mountain. It faces northeast.
Facing northeast at an average 32°, S1 gets about 65% 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 43rd shadiest named run at Aspen Mountain. Its top sits at 10,280 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.
