Black diamond A-Basin, CO
Nose drops 336 vertical feet over 914 feet of skiing, with a steepest pitch of 31° about 610 feet below the top. That's steeper than 64% of the 4,740 black diamond runs we've measured in North America, and the 107th steepest of 161 named runs at A-Basin. It faces east.
Facing east at an average 22°, Nose gets about 93% of the winter sun that flat ground at A-Basin does, December through March. That's sunnier than 64% of the runs we've measured, and the 39th sunniest named run at A-Basin. Its top sits at 12,090 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.
