Facing north at an average 18°, The Back 9 gets about 42% of the winter sun that flat ground at Breckenridge does, December through March. That's shadier than 97% of the runs we've measured, and the 5th shadiest named run at Breckenridge. Its top sits at 11,520 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.
