Black diamond Snowmass, CO
A-Line drops 1,381 vertical feet over 5,316 feet of skiing, with a steepest pitch of 34° about 3,550 feet below the top. That's steeper than 81% of the 4,740 black diamond runs we've measured in North America, and the 37th steepest of 126 named runs at Snowmass. It faces northeast.
Facing northeast at an average 15°, A-Line gets about 72% of the winter sun that flat ground at Snowmass does, December through March. That's shadier than 68% of the runs we've measured, and the 67th shadiest named run at Snowmass. Its top sits at 11,290 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.
