Black diamond Copper, CO
Slip Knot drops 550 vertical feet over 1,325 feet of skiing, with a steepest pitch of 34° about 10 feet below the top. That's steeper than 81% of the 4,740 black diamond runs we've measured in North America, and the 23rd steepest of 141 named runs at Copper. It faces northwest.
Facing northwest at an average 25°, Slip Knot gets about 67% of the winter sun that flat ground at Copper does, December through March. That's shadier than 76% of the runs we've measured, and the 35th shadiest named run at Copper. Its top sits at 11,680 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.
