Double black Blue Mountain, ON
Avalanche drops 328 vertical feet over 1,047 feet of skiing, with a steepest pitch of 33° about 10 feet below the top. That's steeper than 34% of the 2,251 double black runs we've measured in North America, and the 4th steepest of 55 named runs at Blue Mountain. It faces northeast.
Facing northeast at an average 18°, Avalanche gets about 66% of the winter sun that flat ground at Blue Mountain does, December through March. That's shadier than 77% of the runs we've measured, and the 4th shadiest named run at Blue Mountain. Its top sits at 1,230 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.
