Black diamond Sunlight Mountain, CO
Gnarly Knob drops 490 vertical feet over 1,573 feet of skiing, with a steepest pitch of 31° about 490 feet below the top. That's steeper than 63% of the 4,740 black diamond runs we've measured in North America, and the 21st steepest of 69 named runs at Sunlight Mountain. It faces north.
Facing north at an average 18°, Gnarly Knob gets about 50% of the winter sun that flat ground at Sunlight Mountain does, December through March. That's shadier than 93% of the runs we've measured, and the 13th shadiest named run at Sunlight Mountain. Its top sits at 9,080 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.
