Double black Alta, UT
Gun Towers drops 708 vertical feet over 1,314 feet of skiing, with a steepest pitch of 49° about 750 feet below the top. That's steeper than 97% of the 2,251 double black runs we've measured in North America, and the 7th steepest of 117 named runs at Alta. It faces west.
Facing west at an average 33°, Gun Towers gets about 99% of the winter sun that flat ground at Alta does, December through March. That's sunnier than 70% of the runs we've measured, and the 25th sunniest named run at Alta. Its top sits at 9,770 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.
