Blue Bogus Basin, ID
Lower Bonanza drops 474 vertical feet over 1,408 feet of skiing, with a steepest pitch of 26° about 850 feet below the top. That's steeper than 83% of the 5,615 blue runs we've measured in North America, and the 40th steepest of 98 named runs at Bogus Basin. It faces northwest.
Facing northwest at an average 20°, Lower Bonanza gets about 67% of the winter sun that flat ground at Bogus Basin does, December through March. That's shadier than 76% of the runs we've measured, and the 38th shadiest named run at Bogus Basin. Its top sits at 6,800 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.
