Black diamond Keystone, CO
Revolution drops 430 vertical feet over 1,617 feet of skiing, with a steepest pitch of 32° about 50 feet below the top. That's steeper than 70% of the 4,740 black diamond runs we've measured in North America, and the 19th steepest of 140 named runs at Keystone. It faces north.
Facing north at an average 16°, Revolution gets about 58% of the winter sun that flat ground at Keystone does, December through March. That's shadier than 86% of the runs we've measured, and the 10th shadiest named run at Keystone. Its top sits at 11,840 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.
