Double black Silver Mountain, ID
Sliver Basin drops 704 vertical feet over 2,031 feet of skiing, with a steepest pitch of 34° about 1,820 feet below the top. That's steeper than 39% of the 2,251 double black runs we've measured in North America, and the 15th steepest of 69 named runs at Silver Mountain. It faces north.
Facing north at an average 21°, Sliver Basin gets about 44% of the winter sun that flat ground at Silver Mountain does, December through March. That's shadier than 96% of the runs we've measured, and the 8th shadiest named run at Silver Mountain. Its top sits at 5,690 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.
