Double black Sunlight Mountain, CO
Lower Deception drops 500 vertical feet over 1,646 feet of skiing, with a steepest pitch of 23° about 110 feet below the top. That's steeper than 9% of the 2,251 double black runs we've measured in North America, and the 52nd steepest of 69 named runs at Sunlight Mountain. It faces north.
Facing north at an average 18°, Lower Deception gets about 58% of the winter sun that flat ground at Sunlight Mountain does, December through March. That's shadier than 87% of the runs we've measured, and the 23rd shadiest named run at Sunlight Mountain. Its top sits at 8,450 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.
