Blue Mammoth, CA
Main Park Half Pipe drops 203 vertical feet over 687 feet of skiing, with a steepest pitch of 18° about 420 feet below the top. That's steeper than 25% of the 5,615 blue runs we've measured in North America, and the 120th steepest of 151 named runs at Mammoth. It faces northwest.
Facing northwest at an average 17°, Main Park Half Pipe gets about 75% of the winter sun that flat ground at Mammoth does, December through March. That's shadier than 63% of the runs we've measured, and the 80th shadiest named run at Mammoth. Its top sits at 9,190 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.
