Facing northeast at an average 16°, Styx gets about 80% of the winter sun that flat ground at Purgatory does, December through March. That's shadier than 55% of the runs we've measured, and the 53rd shadiest named run at Purgatory. Its top sits at 10,420 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.
