Double black Snowmass, CO
West I drops 435 vertical feet over 1,067 feet of skiing, with a steepest pitch of 51° about 640 feet below the top. That's steeper than 99% of the 2,251 double black runs we've measured in North America, and the 1st steepest of 126 named runs at Snowmass. It faces northeast.
Facing northeast at an average 25°, West I gets about 56% of the winter sun that flat ground at Snowmass does, December through March. That's shadier than 88% of the runs we've measured, and the 10th shadiest named run at Snowmass. Its top sits at 11,910 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.
