Ego Alley drops 454 vertical feet over 1,466 feet of skiing, with a steepest pitch of 22° about 1,370 feet below the top. That's steeper than 11% of the 4,740 black diamond runs we've measured in North America, and the 19th steepest of 74 named runs at Holiday Valley. It faces north.
Facing north at an average 18°, Ego Alley gets about 53% of the winter sun that flat ground at Holiday Valley does, December through March. That's shadier than 91% of the runs we've measured, and the 2nd shadiest named run at Holiday Valley. Its top sits at 2,250 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.
