Blue A-Basin, CO
Humbug drops 267 vertical feet over 1,366 feet of skiing, with a steepest pitch of 21° about 1,100 feet below the top. That's steeper than 44% of the 5,615 blue runs we've measured in North America, and the 148th steepest of 161 named runs at A-Basin. It faces northeast.
Facing northeast at an average 12°, Humbug gets about 84% of the winter sun that flat ground at A-Basin does, December through March. That's sunnier than 52% of the runs we've measured, and the 59th sunniest named run at A-Basin. Its top sits at 12,450 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.
