Blue Pomerelle, ID
Backdoor drops 66 vertical feet over 290 feet of skiing, with a steepest pitch of 16° about 110 feet below the top. That's steeper than 16% of the 5,615 blue runs we've measured in North America, and the 19th steepest of 33 named runs at Pomerelle. It faces north.
Facing north at an average 13°, Backdoor gets about 70% of the winter sun that flat ground at Pomerelle does, December through March. That's shadier than 72% of the runs we've measured, and the 8th shadiest named run at Pomerelle. Its top sits at 7,820 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.
