Blue Snow Summit, CA
Mainstream drops 249 vertical feet over 1,344 feet of skiing, with a steepest pitch of 19° about 150 feet below the top. That's steeper than 35% of the 5,615 blue runs we've measured in North America, and the 21st steepest of 27 named runs at Snow Summit. It faces north.
Facing north at an average 11°, Mainstream gets about 73% of the winter sun that flat ground at Snow Summit does, December through March. That's shadier than 67% of the runs we've measured, and the 14th shadiest named run at Snow Summit. Its top sits at 8,000 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.
