You know what,
I just watched all 6 of the featured resort videos on SkiCanadianRockies.com (In the 6 Mountain Resorts Section). They are well done videos, and I learned the following about each mountain:
Sunshine Village: The chairlift accessible terrain is basically premium backcountry here.
Lake Louise: Is just as good as Sunshine, only with less crowds
Castle Mountain: Has tons of steep terrain, low crowds and is favored by the hardcore locals.
Marmot Basin: Gets super dry deep powder, with 'Heli Skiing' style terrain.
Nakiska: Is a total family mountain
Mt. Norquay: Is the oldest resort in Alberta, with a very old school vibe.
Just thought I would share this with everyone while the snow is still fresh.
