Double black Sunlight Mountain, CO
A3 drops 559 vertical feet over 1,260 feet of skiing, with a steepest pitch of 37° about 160 feet below the top. That's steeper than 51% of the 2,251 double black runs we've measured in North America, and the 9th steepest of 69 named runs at Sunlight Mountain. It faces north.
Facing north at an average 27°, A3 gets about 43% of the winter sun that flat ground at Sunlight Mountain does, December through March. That's shadier than 96% of the runs we've measured, and the 8th shadiest named run at Sunlight Mountain. Its top sits at 8,970 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.
