Double black A-Basin, CO
Pali Cornice drops 320 vertical feet over 1,065 feet of skiing, with a steepest pitch of 24° about 370 feet below the top. That's steeper than 10% of the 2,251 double black runs we've measured in North America, and the 145th steepest of 161 named runs at A-Basin. It faces northwest.
Facing northwest at an average 18°, Pali Cornice gets about 60% of the winter sun that flat ground at A-Basin does, December through March. That's shadier than 85% of the runs we've measured, and the 53rd shadiest named run at A-Basin. Its top sits at 12,120 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.
