Don't get me wrong - Chamonix can be great. I've had 4 trips there and may well go again this season. Altagirl, 'chest-deep powder' - wow, I've probably only experienced that a few times in my life - very jealous!
Pyramid, obviously comparing snow is a pretty futile exercise, particularly with the variety in N American conditions I guess, but futile exercises are fun
So here I go again. Clearly snow anywhere 'can be terrible or can be wonderful' but in my experience it's less likely to be wonderful in Europe. I've probably skied about 400(?) days in Europe and only about 30 in N America (as pyramid says, very limited). However, most of the N American days have been great - far, far better than an average day in Europe.
Now I may just have been lucky (although I did pick Fernie's worst season in a century
: ) and I certainly chose N American resorts which have very good snow records. But in my experience these resorts have better snow than their European conuterparts. Thousands of Europeans travel to North America each year (sorry). Why? It's a long way, expensive, our best resorts are larger, our terrain as challenging. Most of us do it because of snow reliability and snow quality. Apart from me. I do it for the burgers.
Obviously these are generalisations and aren't true of all N American resorts, but I think it's true of the best.
