Green A-Basin, CO
Sundance drops 693 vertical feet over 3,411 feet of skiing, with a steepest pitch of 19° about 2,340 feet below the top. That's steeper than 83% of the 3,109 green runs we've measured in North America, and the 152nd steepest of 161 named runs at A-Basin. It faces north.
Facing north at an average 12°, Sundance gets about 76% of the winter sun that flat ground at A-Basin does, December through March. That's shadier than 61% of the runs we've measured, and the 95th shadiest named run at A-Basin. Its top sits at 11,560 feet.
Shaded snow stays colder and drier, so it holds powder longer after a storm and is slower to crust over or turn to slush in spring. Shading from ridges and trees isn't counted yet.
