Blue Sun Valley, ID
Blue Grouse drops 528 vertical feet over 1,332 feet of skiing, with a steepest pitch of 36° about 1,080 feet below the top. That's steeper than 100% of the 5,615 blue runs we've measured in North America, and the 3rd steepest of 99 named runs at Sun Valley. It faces north.
Facing north at an average 24°, Blue Grouse gets about 47% of the winter sun that flat ground at Sun Valley does, December through March. That's shadier than 95% of the runs we've measured, and the 18th shadiest named run at Sun Valley. Its top sits at 8,340 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.
