Black diamond Whiteface Mountain, NY
Upper Mackenzie drops 635 vertical feet over 1,747 feet of skiing, with a steepest pitch of 33° about 840 feet below the top. That's steeper than 74% of the 4,740 black diamond runs we've measured in North America, and the 10th steepest of 90 named runs at Whiteface Mountain. It faces northeast.
Facing northeast at an average 22°, Upper Mackenzie gets about 75% of the winter sun that flat ground at Whiteface Mountain does, December through March. That's shadier than 62% of the runs we've measured, and the 11th shadiest named run at Whiteface Mountain. Its top sits at 3,210 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.
