Blue Sipapu, NM
Butterfly drops 350 vertical feet over 1,261 feet of skiing, with a steepest pitch of 22° about 900 feet below the top. That's steeper than 58% of the 5,615 blue runs we've measured in North America, and the 19th steepest of 44 named runs at Sipapu. It faces northeast.
Facing northeast at an average 16°, Butterfly gets about 77% of the winter sun that flat ground at Sipapu does, December through March. That's shadier than 60% of the runs we've measured, and the 25th shadiest named run at Sipapu. Its top sits at 8,870 feet.
Shaded snow stays colder and drier, so it holds powder longer after a storm and is slower to crust over or turn to slush in spring. Shading from ridges and trees isn't counted yet.
