Double black Aspen Mountain, CO
Niagara drops 265 vertical feet over 632 feet of skiing, with a steepest pitch of 33° about 30 feet below the top. That's steeper than 34% of the 2,251 double black runs we've measured in North America, and the 72nd steepest of 139 named runs at Aspen Mountain. It faces north.
Facing north at an average 25°, Niagara gets about 40% of the winter sun that flat ground at Aspen Mountain does, December through March. That's shadier than 97% of the runs we've measured, and the 4th shadiest named run at Aspen Mountain. Its top sits at 8,730 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.
