Lofcaudio's lists are in general quite reasonable with the likely omissions being places he has not been.
1) Mammoth should be on the intermediate, advanced and variety lists.
2) Squaw should be on the advanced and expert lists.
3) I doubt Lofcaudio has been any of the places I consider on the elite list of uncrowded, other than Grand Targhee.
Snow conditions can play a role in some of these ratings in terms of how consistent the skiing is at particular levels. Moguls are a good example, as they can be unpleasant when snow preservation is not the greatest. The other point with moguls is spacing, which means they primarily are formed by good bump skiers. Mary Jane's mogul reputation has thus become self reinforcing. I found the longer bump runs at Vail and Beaver Creek to be comparable. Those areas have touristy reputations, but I suspect runs like Prima/Pronto, Highline and Grouse are primarily skied by local bumpers. Other good mogul areas: Aspen Mt., Telluride, Sun Valley, Taos.
I'm big on scenery. Care to give your opinion on that? I would say Lake Louise would top my list in that regard (until I get to Europe the winter after next)
Lake Louise, Heavenly and Telluride are consensus favored North American ski areas for scenery. I would put Alyeska in that group too. Comparable and closer to home for Bigtinnie are a few places in New Zealand like Treble Cone. But many places in the Alps are on a completely different level IMHO, starting with Zermatt and Chamonix IMHO.
Nearly two years ago I was hired to create some lists for ranking North American ski areas by various criteria, but nothing yet has come of this. If these people never bring it off, I will probably put the info on my own website.
I'm a listoholic too, but the problem with overall rankings is that everyone's criteria are different. The
SKI Magazine overall ratings are notorious for assigning equal weights to 15 odd categories, many of which have nothing to do with skiing. The attractive concept for that project above is that the creators planned to allow users to assign personal weights of importance to each criterion.
