I went to UGA and spent a winter here in Summit county...and never went home.
Do you want to live in a mountain town? Or in a city?
If mountain town, I'd consider any of the major CO ski areas; all have great mountain towns adjacent and all hire tons of seasonal work. Restaurant work in the mountains may be a bit tougher to find, unless you have a friend who can hook you up with a job. Unless you want to be in the kitchen.
If you're just going to come out for a season, I'd suggest Aspen, Steamboat , Telluride or Crested Butte; but that's just me.
If you want to be near/in a 'regular' city, I agree with those who suggest SLC.
It will be MUCH tougher to find a place to live than it will a job in a mountain town, btw.
