Facing northeast at an average 28°, Bookmark Gully gets about 54% of the winter sun that flat ground at Snowbird does, December through March. That's shadier than 90% of the runs we've measured, and the 28th shadiest named run at Snowbird. Its top sits at 10,460 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.
