Double black Snowmass, CO
Upper Ladder drops 647 vertical feet over 1,839 feet of skiing, with a steepest pitch of 42° about 1,690 feet below the top. That's steeper than 77% of the 2,251 double black runs we've measured in North America, and the 15th steepest of 126 named runs at Snowmass. It faces north.
Facing north at an average 21°, Upper Ladder gets about 47% of the winter sun that flat ground at Snowmass does, December through March. That's shadier than 95% of the runs we've measured, and the shadiest named run at Snowmass. Its top sits at 11,810 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.
