Facing north at an average 17°, Callie's Alley gets about 64% of the winter sun that flat ground at Breckenridge does, December through March. That's shadier than 80% of the runs we've measured, and the 32nd shadiest named run at Breckenridge. Its top sits at 11,040 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.
