Blue Sunlight Mountain, CO
Cornice drops 729 vertical feet over 4,256 feet of skiing, with a steepest pitch of 19° about 140 feet below the top. That's steeper than 32% of the 5,615 blue runs we've measured in North America, and the 57th steepest of 69 named runs at Sunlight Mountain. It faces north.
Facing north at an average 10°, Cornice gets about 75% of the winter sun that flat ground at Sunlight Mountain does, December through March. That's shadier than 62% of the runs we've measured, and the 46th shadiest named run at Sunlight Mountain. Its top sits at 9,300 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.
