Black diamond Silver Mountain, ID
Corkscrew drops 320 vertical feet over 842 feet of skiing, with a steepest pitch of 37° about 60 feet below the top. That's steeper than 91% of the 4,740 black diamond runs we've measured in North America, and the 6th steepest of 69 named runs at Silver Mountain. It faces northeast.
Facing northeast at an average 23°, Corkscrew gets about 72% of the winter sun that flat ground at Silver Mountain does, December through March. That's shadier than 68% of the runs we've measured, and the 42nd shadiest named run at Silver Mountain. Its top sits at 5,890 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.
