Black diamond Silver Mountain, ID
Jackass drops 504 vertical feet over 1,107 feet of skiing, with a steepest pitch of 33° about 550 feet below the top. That's steeper than 76% of the 4,740 black diamond runs we've measured in North America, and the 21st steepest of 69 named runs at Silver Mountain. It faces northwest.
Facing northwest at an average 27°, Jackass gets about 41% of the winter sun that flat ground at Silver Mountain does, December through March. That's shadier than 97% of the runs we've measured, and the 3rd shadiest named run at Silver Mountain. Its top sits at 4,990 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.
