Green Sun Valley, ID
Mid Warm Springs drops 538 vertical feet over 1,628 feet of skiing, with a steepest pitch of 25° about 10 feet below the top. That's steeper than 97% of the 3,109 green runs we've measured in North America, and the 69th steepest of 99 named runs at Sun Valley. It faces north.
Facing north at an average 19°, Mid Warm Springs gets about 53% of the winter sun that flat ground at Sun Valley does, December through March. That's shadier than 91% of the runs we've measured, and the 33rd shadiest named run at Sun Valley. Its top sits at 7,800 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.
