Black diamond A-Basin, CO
Bighorn drops 676 vertical feet over 1,890 feet of skiing, with a steepest pitch of 34° about 1,720 feet below the top. That's steeper than 81% of the 4,740 black diamond runs we've measured in North America, and the 77th steepest of 161 named runs at A-Basin. It faces west.
Facing west at an average 21°, Bighorn gets about 94% of the winter sun that flat ground at A-Basin does, December through March. That's sunnier than 65% of the runs we've measured, and the 36th sunniest named run at A-Basin. Its top sits at 11,940 feet.
With little slope to hide behind, it takes nearly the full winter sun of open ground: powder settles and turns heavy sooner after a storm, and spring snow softens early. Shading from ridges and trees isn't counted yet.
