Blue Lost Trail, MT
Bill's Run drops 187 vertical feet over 766 feet of skiing, with a steepest pitch of 17° about 170 feet below the top. That's steeper than 24% of the 5,615 blue runs we've measured in North America, and the 55th steepest of 67 named runs at Lost Trail. It faces northeast.
Facing northeast at an average 14°, Bill's Run gets about 65% of the winter sun that flat ground at Lost Trail does, December through March. That's shadier than 79% of the runs we've measured, and the 6th shadiest named run at Lost Trail. Its top sits at 7,240 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.
