Black diamond Keystone, CO
Starfire drops 1,584 vertical feet over 5,010 feet of skiing, with a steepest pitch of 25° about 4,230 feet below the top. That's steeper than 24% of the 4,740 black diamond runs we've measured in North America, and the 61st steepest of 140 named runs at Keystone. It faces west.
Facing west at an average 19°, Starfire gets about 85% of the winter sun that flat ground at Keystone does, December through March. That's sunnier than 53% of the runs we've measured, and the 59th sunniest named run at Keystone. Its top sits at 11,630 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.
