Swiss Twist drops 329 vertical feet over 2,047 feet of skiing, with a steepest pitch of 17° about 770 feet below the top. That's steeper than 4% of the 4,740 black diamond runs we've measured in North America, and the 39th steepest of 74 named runs at Holiday Valley. It faces north.
Facing north at an average 10°, Swiss Twist gets about 68% of the winter sun that flat ground at Holiday Valley does, December through March. That's shadier than 74% of the runs we've measured, and the 23rd shadiest named run at Holiday Valley. Its top sits at 2,220 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.
