Black diamond Alpine Meadows, CA
Lower 40 Face drops 570 vertical feet over 1,005 feet of skiing, with a steepest pitch of 48° about 250 feet below the top. That's steeper than 100% of the 4,740 black diamond runs we've measured in North America, and the 10th steepest of 132 named runs at Alpine Meadows. It faces west.
Facing west at an average 36°, Lower 40 Face gets about 75% of the winter sun that flat ground at Alpine Meadows does, December through March. That's shadier than 63% of the runs we've measured, and the 59th shadiest named run at Alpine Meadows. Its top sits at 7,710 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.
