Black diamond Kelly Canyon, ID
Black Powder drops 349 vertical feet over 1,557 feet of skiing, with a steepest pitch of 21° about 880 feet below the top. That's steeper than 10% of the 4,740 black diamond runs we've measured in North America, and the 27th steepest of 49 named runs at Kelly Canyon. It faces north.
Facing north at an average 13°, Black Powder gets about 64% of the winter sun that flat ground at Kelly Canyon does, December through March. That's shadier than 79% of the runs we've measured, and the 16th shadiest named run at Kelly Canyon. Its top sits at 6,630 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.
