Blue Kelly Canyon, ID
Waterfall drops 161 vertical feet over 451 feet of skiing, with a steepest pitch of 25° about 370 feet below the top. That's steeper than 79% of the 5,615 blue runs we've measured in North America, and the 15th steepest of 49 named runs at Kelly Canyon. It faces northeast.
Facing northeast at an average 21°, Waterfall gets about 57% of the winter sun that flat ground at Kelly Canyon does, December through March. That's shadier than 87% of the runs we've measured, and the 3rd shadiest named run at Kelly Canyon. Its top sits at 6,520 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.
