Double black Bogus Basin, ID
Waterfall drops 617 vertical feet over 1,564 feet of skiing, with a steepest pitch of 35° about 730 feet below the top. That's steeper than 44% of the 2,251 double black runs we've measured in North America, and the 5th steepest of 98 named runs at Bogus Basin. It faces northeast.
Facing northeast at an average 24°, Waterfall gets about 69% of the winter sun that flat ground at Bogus Basin does, December through March. That's shadier than 72% of the runs we've measured, and the 42nd shadiest named run at Bogus Basin. Its top sits at 6,690 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.
