Double black Red Lodge, MT
Sluice Box drops 881 vertical feet over 2,113 feet of skiing, with a steepest pitch of 34° about 1,080 feet below the top. That's steeper than 38% of the 2,251 double black runs we've measured in North America, and the 9th steepest of 54 named runs at Red Lodge. It faces north.
Facing north at an average 25°, Sluice Box gets about 33% of the winter sun that flat ground at Red Lodge does, December through March. That's shadier than 99% of the runs we've measured, and the shadiest named run at Red Lodge. Its top sits at 9,090 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.
