Black diamond Alta, UT
Sidewinder drops 1,119 vertical feet over 4,201 feet of skiing, with a steepest pitch of 37° about 220 feet below the top. That's steeper than 91% of the 4,740 black diamond runs we've measured in North America, and the 43rd steepest of 117 named runs at Alta. It faces west.
Facing west at an average 17°, Sidewinder gets about 94% of the winter sun that flat ground at Alta does, December through March. That's sunnier than 65% of the runs we've measured, and the 30th sunniest named run at Alta. Its top sits at 10,490 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.
