Blue Snowbasin, UT
Lo Fro Zone drops 308 vertical feet over 1,354 feet of skiing, with a steepest pitch of 27° about 650 feet below the top. That's steeper than 88% of the 5,615 blue runs we've measured in North America, and the 79th steepest of 127 named runs at Snowbasin. It faces northeast.
Facing northeast at an average 13°, Lo Fro Zone gets about 75% of the winter sun that flat ground at Snowbasin does, December through March. That's shadier than 63% of the runs we've measured, and the 34th shadiest named run at Snowbasin. Its top sits at 8,420 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.
