Black diamond Mountain High, CA
Backfire drops 276 vertical feet over 811 feet of skiing, with a steepest pitch of 29° about 160 feet below the top. That's steeper than 48% of the 4,740 black diamond runs we've measured in North America, and the 7th steepest of 37 named runs at Mountain High. It faces northeast.
Facing northeast at an average 20°, Backfire gets about 83% of the winter sun that flat ground at Mountain High does, December through March. That's shadier than 50% of the runs we've measured, and the 30th shadiest named run at Mountain High. Its top sits at 7,480 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.
