Blue Alta, UT
Big Dipper drops 835 vertical feet over 5,383 feet of skiing, with a steepest pitch of 19° about 3,480 feet below the top. That's steeper than 35% of the 5,615 blue runs we've measured in North America, and the 107th steepest of 117 named runs at Alta. It faces west.
Facing west at an average 9°, Big Dipper gets about 93% of the winter sun that flat ground at Alta does, December through March. That's sunnier than 64% of the runs we've measured, and the 32nd sunniest named run at Alta. Its top sits at 10,470 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.
