Black diamond Aspen Mountain, CO
Northstar drops 183 vertical feet over 489 feet of skiing, with a steepest pitch of 27° about 440 feet below the top. That's steeper than 34% of the 4,740 black diamond runs we've measured in North America, and the 109th steepest of 139 named runs at Aspen Mountain. It faces northeast.
Facing northeast at an average 22°, Northstar gets about 69% of the winter sun that flat ground at Aspen Mountain does, December through March. That's shadier than 73% of the runs we've measured, and the 58th shadiest named run at Aspen Mountain. Its top sits at 10,760 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.
