Aces drops 124 vertical feet over 369 feet of skiing, with a steepest pitch of 21° about 150 feet below the top. That's steeper than 45% of the 5,615 blue runs we've measured in North America, and the 20th steepest of 52 named runs at Ski Mystic Deer Mountain. It faces northwest.
Facing northwest at an average 20°, Aces gets about 67% of the winter sun that flat ground at Ski Mystic Deer Mountain does, December through March. That's shadier than 76% of the runs we've measured, and the 3rd shadiest named run at Ski Mystic Deer Mountain. Its top sits at 6,340 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.
