Green Kelly Canyon, ID
Old Man's Flats drops 114 vertical feet over 1,076 feet of skiing, with a steepest pitch of 13° about 1,060 feet below the top. That's steeper than 39% of the 3,109 green runs we've measured in North America, and the 45th steepest of 49 named runs at Kelly Canyon. It faces north.
Facing north at an average 6°, Old Man's Flats gets about 75% of the winter sun that flat ground at Kelly Canyon does, December through March. That's shadier than 63% of the runs we've measured, and the 34th shadiest named run at Kelly Canyon. Its top sits at 6,180 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.
