Blue Snow King, WY
Kelly's Alley drops 291 vertical feet over 935 feet of skiing, with a steepest pitch of 26° about 720 feet below the top. That's steeper than 85% of the 5,615 blue runs we've measured in North America, and the 19th steepest of 33 named runs at Snow King. It faces north.
Facing north at an average 18°, Kelly's Alley gets about 45% of the winter sun that flat ground at Snow King does, December through March. That's shadier than 96% of the runs we've measured, and the 18th shadiest named run at Snow King. Its top sits at 6,770 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.
