Black diamond Bogus Basin, ID
Blackbird drops 375 vertical feet over 1,253 feet of skiing, with a steepest pitch of 26° about 500 feet below the top. That's steeper than 31% of the 4,740 black diamond runs we've measured in North America, and the 38th steepest of 98 named runs at Bogus Basin. It faces northwest.
Facing northwest at an average 18°, Blackbird gets about 76% of the winter sun that flat ground at Bogus Basin does, December through March. That's shadier than 62% of the runs we've measured, and the 51st shadiest named run at Bogus Basin. Its top sits at 6,740 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.
