Double black Loveland, CO
Rainbow drops 184 vertical feet over 398 feet of skiing, with a steepest pitch of 37° about 10 feet below the top. That's steeper than 54% of the 2,251 double black runs we've measured in North America, and the 11th steepest of 81 named runs at Loveland. It faces north.
Facing north at an average 28°, Rainbow gets about 36% of the winter sun that flat ground at Loveland does, December through March. That's shadier than 99% of the runs we've measured, and the shadiest named run at Loveland. Its top sits at 11,070 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.
