Green Sun Valley, ID
Lilly Marlane drops 378 vertical feet over 4,186 feet of skiing, with a steepest pitch of 11° about 1,660 feet below the top. That's steeper than 26% of the 3,109 green runs we've measured in North America, and the 96th steepest of 99 named runs at Sun Valley. It faces north.
Facing north at an average 5°, Lilly Marlane gets about 57% of the winter sun that flat ground at Sun Valley does, December through March. That's shadier than 87% of the runs we've measured, and the 46th shadiest named run at Sun Valley. Its top sits at 7,310 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.
