Green Vail, CO
Sourdough drops 394 vertical feet over 1,831 feet of skiing, with a steepest pitch of 20° about 720 feet below the top. That's steeper than 88% of the 3,109 green runs we've measured in North America, and the 158th steepest of 194 named runs at Vail. It faces northwest.
Facing northwest at an average 13°, Sourdough gets about 80% of the winter sun that flat ground at Vail does, December through March. That's shadier than 55% of the runs we've measured, and the 116th shadiest named run at Vail. Its top sits at 11,210 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.
