Facing northwest at an average 8°, Porcupine gets about 81% of the winter sun that flat ground at White Pine does, December through March. That's shadier than 53% of the runs we've measured, and the 21st shadiest named run at White Pine. Its top sits at 8,720 feet.
It gets an ordinary dose of sun: powder lasts a typical amount of time, and spring snow softens on a normal schedule. Shading from ridges and trees isn't counted yet.
