Black diamond Deer Valley, UT
Rattler drops 766 vertical feet over 2,199 feet of skiing, with a steepest pitch of 30° about 740 feet below the top. That's steeper than 58% of the 4,740 black diamond runs we've measured in North America, and the 64th steepest of 224 named runs at Deer Valley. It faces north.
Facing north at an average 21°, Rattler gets about 55% of the winter sun that flat ground at Deer Valley does, December through March. That's shadier than 89% of the runs we've measured, and the 11th shadiest named run at Deer Valley. Its top sits at 8,690 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.
