Black diamond Sunlight Mountain, CO
Perry's Plunge drops 747 vertical feet over 2,140 feet of skiing, with a steepest pitch of 33° about 1,400 feet below the top. That's steeper than 74% of the 4,740 black diamond runs we've measured in North America, and the 17th steepest of 69 named runs at Sunlight Mountain. It faces north.
Facing north at an average 21°, Perry's Plunge gets about 51% of the winter sun that flat ground at Sunlight Mountain does, December through March. That's shadier than 92% of the runs we've measured, and the 14th shadiest named run at Sunlight Mountain. Its top sits at 9,190 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.
