Blue A-Basin, CO
Moose Hollow drops 51 vertical feet over 542 feet of skiing, with a steepest pitch of 12° about 80 feet below the top. That's steeper than 5% of the 5,615 blue runs we've measured in North America, and the 159th steepest of 161 named runs at A-Basin. It faces west.
Facing west at an average 6°, Moose Hollow gets about 92% of the winter sun that flat ground at A-Basin does, December through March. That's sunnier than 63% of the runs we've measured, and the 40th sunniest named run at A-Basin. Its top sits at 11,020 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.
