Black diamond Sun Valley, ID
Lower Flying Squirrel drops 666 vertical feet over 1,595 feet of skiing, with a steepest pitch of 32° about 850 feet below the top. That's steeper than 71% of the 4,740 black diamond runs we've measured in North America, and the 14th steepest of 99 named runs at Sun Valley. It faces northwest.
Facing northwest at an average 25°, Lower Flying Squirrel gets about 65% of the winter sun that flat ground at Sun Valley does, December through March. That's shadier than 79% of the runs we've measured, and the 55th shadiest named run at Sun Valley. Its top sits at 7,300 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.
