Double black Grand Targhee, WY
Cornice Interruptus drops 482 vertical feet over 1,226 feet of skiing, with a steepest pitch of 50° about 430 feet below the top. That's steeper than 98% of the 2,251 double black runs we've measured in North America, and the 3rd steepest of 83 named runs at Grand Targhee. It faces north.
Facing north at an average 25°, Cornice Interruptus gets about 51% of the winter sun that flat ground at Grand Targhee does, December through March. That's shadier than 92% of the runs we've measured, and the 6th shadiest named run at Grand Targhee. Its top sits at 9,490 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.
