Blue Granite Peak, WI
Birch drops 398 vertical feet over 1,920 feet of skiing, with a steepest pitch of 23° about 470 feet below the top. That's steeper than 65% of the 5,615 blue runs we've measured in North America, and the 18th steepest of 59 named runs at Granite Peak. It faces north.
Facing north at an average 12°, Birch gets about 66% of the winter sun that flat ground at Granite Peak does, December through March. That's shadier than 77% of the runs we've measured, and the 21st 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.
