Black diamond Northstar, CA
Prosser drops 1,744 vertical feet over 6,020 feet of skiing, with a steepest pitch of 29° about 3,690 feet below the top. That's steeper than 51% of the 4,740 black diamond runs we've measured in North America, and the 9th steepest of 90 named runs at Northstar. It faces north.
Facing north at an average 17°, Prosser gets about 58% of the winter sun that flat ground at Northstar does, December through March. That's shadier than 86% of the runs we've measured, and the 4th shadiest named run at Northstar. Its top sits at 8,070 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.
