Blue Bogus Basin, ID
Bitterroot Basin drops 407 vertical feet over 1,568 feet of skiing, with a steepest pitch of 25° about 310 feet below the top. That's steeper than 76% of the 5,615 blue runs we've measured in North America, and the 47th steepest of 98 named runs at Bogus Basin. It faces northeast.
Facing northeast at an average 15°, Bitterroot Basin gets about 61% of the winter sun that flat ground at Bogus Basin does, December through March. That's shadier than 84% of the runs we've measured, and the 28th shadiest named run at Bogus Basin. Its top sits at 6,640 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.
