Black diamond Mountain High, CA
Inferno Ridge drops 261 vertical feet over 1,513 feet of skiing, with a steepest pitch of 19° about 1,020 feet below the top. That's steeper than 7% of the 4,740 black diamond runs we've measured in North America, and the 24th steepest of 37 named runs at Mountain High. It faces north.
Facing north at an average 10°, Inferno Ridge gets about 80% of the winter sun that flat ground at Mountain High does, December through March. That's shadier than 54% of the runs we've measured, and the 24th shadiest named run at Mountain High. Its top sits at 7,740 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.
