Here are my thoughts (I ski Utah at least once a year and I hit at least 4 areas each time): Park City the most underwhelming resort I have ever skied - poorly layed out. Brighton - nice good terrain but with boarders in abundance and most using the patented Side Slid Pow Buldozer why bother. Alta - (Angels singing in background) Great snow, lots of snow, no boarders - says it all I think, most underrated resort ever. Deer Valley - great moguls, odd spread out layout, lots of groomed runs, oddly really good on fresh snow days since all the pow hounds are fighting for tracks at Alta, Snowbird, Brighton (boarders). Snowbird - super great terrain (the best for all intents), great snow, lots of snow, but with boarders and crowds - a great resort with issues. Canyons or is it Park West or is it Wolf something or other . . . Well, I just never got the hang of this place so I avoid it like the palgue. Prolly to my loss but what the hay or is it hey? Snow Basin - great lodges, good snow, fair terrain, low crowds a good place to ski if you ask me but a bit far from Salt Lick or Park City. Solitude - oddly now one of my favorites, low crowds, good snow, good terrain although somewhat limited when compared to Alta or Snowbird but the low crowds make up for it and while it allows boarders they don't dominate the area or seem to bulldoze snow quite so badly.
Note my only complaint about boarders is the bad habit of the many. That being turning the board sideways and plowing huge swaths of pow instead of riding it. Get three or 4 of these yahoos and they can burn up pow at an astonishing rate.
