Black diamond Massif Du Sud, QC
La Grande Allée drops 884 vertical feet over 3,075 feet of skiing, with a steepest pitch of 27° about 580 feet below the top. That's steeper than 37% of the 4,740 black diamond runs we've measured in North America, and the 9th steepest of 27 named runs at Massif Du Sud. It faces north.
Facing north at an average 17°, La Grande Allée gets about 53% of the winter sun that flat ground at Massif Du Sud does, December through March. That's shadier than 91% of the runs we've measured, and the 8th shadiest named run at Massif Du Sud. Its top sits at 2,600 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.
