There are many "Best ski resort" lists. Most of them try to accomodate the fact that different people care about different things: terrain, snow, nightlife, other activities, family friendly, etc. This list is just about the quality of the skiing itself for expert skiers (and boaders, with the exception of the top-rated one).Think I'm wrong? Make your own version.
500 inches of the nation's best snow, falling on amazing terrain. No snowboarders allowed last I checked. see more on Alta Ski Area
