Blue Telluride, CO
Butterfly drops 598 vertical feet over 2,510 feet of skiing, with a steepest pitch of 21° about 1,440 feet below the top. That's steeper than 44% of the 5,615 blue runs we've measured in North America, and the 116th steepest of 137 named runs at Telluride. It faces west.
Facing west at an average 14°, Butterfly gets about 103% of the winter sun that flat ground at Telluride does, December through March. That's sunnier than 74% of the runs we've measured, and the 7th sunniest named run at Telluride. Its top sits at 10,510 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.
