Blue Teton Pass, MT
Whoop Up drops 377 vertical feet over 1,287 feet of skiing, with a steepest pitch of 25° about 100 feet below the top. That's steeper than 77% of the 5,615 blue runs we've measured in North America, and the 22nd steepest of 38 named runs at Teton Pass. It faces east.
Facing east at an average 17°, Whoop Up gets about 104% of the winter sun that flat ground at Teton Pass does, December through March. That's sunnier than 75% of the runs we've measured, and the 20th sunniest named run at Teton Pass. Its top sits at 6,580 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.
