Blue Mammoth, CA
Big Bird drops 321 vertical feet over 3,278 feet of skiing, with a steepest pitch of 16° about 300 feet below the top. That's steeper than 16% of the 5,615 blue runs we've measured in North America, and the 129th steepest of 151 named runs at Mammoth. It faces north.
Facing north at an average 6°, Big Bird gets about 79% of the winter sun that flat ground at Mammoth does, December through March. That's shadier than 57% of the runs we've measured, and the 98th shadiest named run at Mammoth. Its top sits at 9,050 feet.
It gets an ordinary dose of sun: powder lasts a typical amount of time, and spring snow softens on a normal schedule. Shading from ridges and trees isn't counted yet.
