Blue White Pass, WA
Northern Sky drops 819 vertical feet over 3,975 feet of skiing, with a steepest pitch of 26° about 640 feet below the top. That's steeper than 85% of the 5,615 blue runs we've measured in North America, and the 30th steepest of 66 named runs at White Pass. It faces north.
Facing north at an average 12°, Northern Sky gets about 67% of the winter sun that flat ground at White Pass does, December through March. That's shadier than 75% of the runs we've measured, and the 19th shadiest named run at White Pass. Its top sits at 6,440 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.
