Double black Mt Baldy, CA
Nightmare drops 664 vertical feet over 1,139 feet of skiing, with a steepest pitch of 38° about 30 feet below the top. That's steeper than 62% of the 2,251 double black runs we've measured in North America, and the 2nd steepest of 26 named runs at Mt Baldy. It faces northwest.
Facing northwest at an average 36°, Nightmare gets about 65% of the winter sun that flat ground at Mt Baldy does, December through March. That's shadier than 79% of the runs we've measured, and the 5th shadiest named run at Mt Baldy. Its top sits at 7,610 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.
