Black diamond Granite Peak, WI
Upper Dusky drops 351 vertical feet over 1,535 feet of skiing, with a steepest pitch of 21° about 740 feet below the top. That's steeper than 9% of the 4,740 black diamond runs we've measured in North America, and the 26th steepest of 59 named runs at Granite Peak. It faces north.
Facing north at an average 13°, Upper Dusky gets about 62% of the winter sun that flat ground at Granite Peak does, December through March. That's shadier than 82% of the runs we've measured, and the 14th shadiest named run at Granite Peak. Its top sits at 1,800 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.
