Here is a few details about the quebec measurements. I keep track of about 30 representative (by region) ski areas in the province for the last 5 years. Unfortunately, the snowfalls measurements are purely marketing for a lot of mountains. Example : the neighbour of Mt Tremblant, Mont Blanc, is exactly copying the snowfalls of Tremblant, which are taken at the summit (1000' over the summit of Mt Blanc). In the St-Sauveur valley, all the ski areas have the same snowfalls, while Ski Morin Heights is getting almost twice what the other areas get, as it's in a special micro-climate. Most of the ski areas forget to count a lot of storms or the cheat. It's why it's tough to see what is real and what is not.
So here is a list of a few ski areas where I think the accumulations are enough fair, but I still indicated if in my opinion the accumulations are possibly a little bit overestimated or lowerestimated.
Sorry if it's a little bit small... 480px oblige...
As you can see, the 2000-01 season was a killer one in the province, especially in the townships. Owl's Head (not present in the list, cause they didn't compile stats in 2004-05 so it was a bad snow year) got 300 inches of snow that year, which is incredibly good for a ski area in the province ! Sutton probably got it also, that year, but they measure snow only at the bottom of the mountain, while the other ski areas of the townships measure the snow at the top, I seriously think.
In general, it's the Massif du Sud and the Valinouet, which receive around 200 inches by year in average that lead the snowfalls in the province. Both mountains are high in elevation, with a base around 1700 feet and have a mountain climate, it's why they get more snow than the other places
Well, it's about that
