Double black Snowmass, CO
Roberto's drops 715 vertical feet over 3,080 feet of skiing, with a steepest pitch of 46° about 1,460 feet below the top. That's steeper than 92% of the 2,251 double black runs we've measured in North America, and the 8th steepest of 126 named runs at Snowmass. It faces northeast.
Facing northeast at an average 14°, Roberto's gets about 76% of the winter sun that flat ground at Snowmass does, December through March. That's shadier than 61% of the runs we've measured, and the 91st shadiest named run at Snowmass. Its top sits at 12,060 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.
