Black diamond Lost Trail, MT
Femur Ridge drops 342 vertical feet over 1,486 feet of skiing, with a steepest pitch of 38° about 860 feet below the top. That's steeper than 93% of the 4,740 black diamond runs we've measured in North America, and the 12th steepest of 67 named runs at Lost Trail. It faces northeast.
Facing northeast at an average 14°, Femur Ridge gets about 51% of the winter sun that flat ground at Lost Trail does, December through March. That's shadier than 92% of the runs we've measured, and the 2nd shadiest named run at Lost Trail. Its top sits at 7,420 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.
