Black diamond Park City, UT
Illusion drops 110 vertical feet over 1,311 feet of skiing, with a steepest pitch of 21° about 10 feet below the top. That's steeper than 9% of the 4,740 black diamond runs we've measured in North America, and the 260th steepest of 334 named runs at Park City. It faces northeast.
Facing northeast at an average 5°, Illusion gets about 75% of the winter sun that flat ground at Park City does, December through March. That's shadier than 63% of the runs we've measured, and the 119th shadiest named run at Park City. Its top sits at 8,330 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.
