Black diamond Alta, UT
Columbine drops 502 vertical feet over 1,145 feet of skiing, with a steepest pitch of 37° about 10 feet below the top. That's steeper than 91% of the 4,740 black diamond runs we've measured in North America, and the 42nd steepest of 117 named runs at Alta. It faces west.
Facing west at an average 26°, Columbine gets about 103% of the winter sun that flat ground at Alta does, December through March. That's sunnier than 74% of the runs we've measured, and the 20th sunniest named run at Alta. Its top sits at 10,100 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.
