Double black Telluride, CO
Roy Boy drops 573 vertical feet over 1,072 feet of skiing, with a steepest pitch of 41° about 620 feet below the top. That's steeper than 74% of the 2,251 double black runs we've measured in North America, and the 23rd steepest of 137 named runs at Telluride. It faces northeast.
Facing northeast at an average 33°, Roy Boy gets about 39% of the winter sun that flat ground at Telluride does, December through March. That's shadier than 98% of the runs we've measured, and the 2nd shadiest named run at Telluride. Its top sits at 12,990 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.
