Black diamond Cannon Mountain, NH
Avalanche drops 661 vertical feet over 1,794 feet of skiing, with a steepest pitch of 31° about 690 feet below the top. That's steeper than 63% of the 4,740 black diamond runs we've measured in North America, and the 6th steepest of 92 named runs at Cannon Mountain. It faces northeast.
Facing northeast at an average 22°, Avalanche gets about 66% of the winter sun that flat ground at Cannon Mountain does, December through March. That's shadier than 77% of the runs we've measured, and the 58th shadiest named run at Cannon Mountain. Its top sits at 2,670 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.
