Blue Kelly Canyon, ID
Slithery Dee drops 281 vertical feet over 1,316 feet of skiing, with a steepest pitch of 20° about 890 feet below the top. That's steeper than 38% of the 5,615 blue runs we've measured in North America, and the 34th steepest of 49 named runs at Kelly Canyon. It faces north.
Facing north at an average 12°, Slithery Dee gets about 64% of the winter sun that flat ground at Kelly Canyon does, December through March. That's shadier than 80% of the runs we've measured, and the 14th shadiest named run at Kelly Canyon. Its top sits at 6,310 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.
