Facing northeast at an average 14°, Upper College gets about 68% of the winter sun that flat ground at Sun Valley does, December through March. That's shadier than 75% of the runs we've measured, and the 60th shadiest named run at Sun Valley. Its top sits at 9,030 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.
