How well Single Jack holds snow

Snow preservationExcellent

Facing north at an average 15°, Single Jack gets about 61% of the winter sun that flat ground at Big Sky does, December through March. That's shadier than 83% of the runs we've measured, and the 43rd shadiest named run at Big Sky. Its top sits at 8,400 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.
