Knife Ridge Gully #1 drops 257 vertical feet over 457 feet of skiing, with a steepest pitch of 47° about 50 feet below the top. That's steeper than 95% of the 2,251 double black runs we've measured in North America, and the 9th steepest of 131 named runs at Wolf Creek. It faces north.
Facing north at an average 35°, Knife Ridge Gully #1 gets about 37% of the winter sun that flat ground at Wolf Creek does, December through March. That's shadier than 98% of the runs we've measured, and the 4th shadiest named run at Wolf Creek. Its top sits at 11,560 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.
