Black diamond Swain Resort, NY
Old Main drops 151 vertical feet over 652 feet of skiing, with a steepest pitch of 21° about 410 feet below the top. That's steeper than 9% of the 4,740 black diamond runs we've measured in North America, and the 13th steepest of 35 named runs at Swain Resort. It faces north.
Facing north at an average 14°, Old Main gets about 67% of the winter sun that flat ground at Swain Resort does, December through March. That's shadier than 76% of the runs we've measured, and the 11th shadiest named run at Swain Resort. Its top sits at 1,480 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.
