Black diamond Crystal Mountain, WA
Lower Otto Bahn drops 518 vertical feet over 2,793 feet of skiing, with a steepest pitch of 21° about 2,410 feet below the top. That's steeper than 10% of the 4,740 black diamond runs we've measured in North America, and the 120th steepest of 133 named runs at Crystal Mountain. It faces north.
Facing north at an average 11°, Lower Otto Bahn gets about 70% of the winter sun that flat ground at Crystal Mountain does, December through March. That's shadier than 71% of the runs we've measured, and the 25th shadiest named run at Crystal Mountain. Its top sits at 5,550 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.
