I'll post pictures of my 30 days in the Canadian rockies last year (and surrounding mountain ranges)... There were a couple days that weren't perfect, but I had fresh powder at least 10 of those days, and great groomed conditions the rest!
We had a great year!
I started boarding mid November and my last day was mid May!
Lake Louise had between 8-9m (27-30 ft or so) of snowfall depending on where you measured.
Fernie had over 11m of snow (37+ ft)
Sunshine had 10m or so
