Blue Lookout Pass, ID
Interstate drops 408 vertical feet over 1,309 feet of skiing, with a steepest pitch of 29° about 740 feet below the top. That's steeper than 93% of the 5,615 blue runs we've measured in North America, and the 13th steepest of 49 named runs at Lookout Pass. It faces northeast.
Facing northeast at an average 18°, Interstate gets about 71% of the winter sun that flat ground at Lookout Pass does, December through March. That's shadier than 69% of the runs we've measured, and the 14th shadiest named run at Lookout Pass. Its top sits at 5,520 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.
