Blue Silver Mountain, ID
Lower Centennial drops 706 vertical feet over 3,182 feet of skiing, with a steepest pitch of 28° about 440 feet below the top. That's steeper than 91% of the 5,615 blue runs we've measured in North America, and the 38th steepest of 69 named runs at Silver Mountain. It faces north.
Facing north at an average 13°, Lower Centennial gets about 50% of the winter sun that flat ground at Silver Mountain does, December through March. That's shadier than 93% of the runs we've measured, and the 16th shadiest named run at Silver Mountain. Its top sits at 4,880 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.
