Double black Copper, CO
Calendar Chute drops 408 vertical feet over 930 feet of skiing, with a steepest pitch of 37° about 370 feet below the top. That's steeper than 55% of the 2,251 double black runs we've measured in North America, and the 12th steepest of 141 named runs at Copper. It faces northeast.
Facing northeast at an average 26°, Calendar Chute gets about 72% of the winter sun that flat ground at Copper does, December through March. That's shadier than 68% of the runs we've measured, and the 61st shadiest named run at Copper. Its top sits at 12,250 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.
