Black diamond Brundage, ID
Hidden Valley drops 148 vertical feet over 704 feet of skiing, with a steepest pitch of 32° about 10 feet below the top. That's steeper than 72% of the 4,740 black diamond runs we've measured in North America, and the 10th steepest of 76 named runs at Brundage. It faces northwest.
Facing northwest at an average 13°, Hidden Valley gets about 61% of the winter sun that flat ground at Brundage does, December through March. That's shadier than 83% of the runs we've measured, and the 11th shadiest named run at Brundage. Its top sits at 7,410 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.
