Blue Silver Mountain, ID
Half Pipe drops 307 vertical feet over 1,008 feet of skiing, with a steepest pitch of 30° about 550 feet below the top. That's steeper than 96% of the 5,615 blue runs we've measured in North America, and the 30th steepest of 69 named runs at Silver Mountain. It faces north.
Facing north at an average 18°, Half Pipe gets about 48% of the winter sun that flat ground at Silver Mountain does, December through March. That's shadier than 94% of the runs we've measured, and the 11th shadiest named run at Silver Mountain. Its top sits at 5,510 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.
