Double black Silver Star, BC
Rusty Whistle drops 763 vertical feet over 1,918 feet of skiing. It faces north.
Facing north at an average 24°, Rusty Whistle gets about 31% of the winter sun that flat ground at Silver Star does, December through March. That's shadier than 99% of the runs we've measured, and the 4th shadiest named run at Silver Star. Its top sits at 5,350 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.
