Black diamond Blacktail, MT
White River drops 690 vertical feet over 2,627 feet of skiing, with a steepest pitch of 23° about 120 feet below the top. That's steeper than 15% of the 4,740 black diamond runs we've measured in North America, and the 9th steepest of 20 named runs at Blacktail. It faces north.
Facing north at an average 15°, White River gets about 62% of the winter sun that flat ground at Blacktail does, December through March. That's shadier than 82% of the runs we've measured, and the 8th shadiest named run at Blacktail. Its top sits at 6,110 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.
