if you're into the punk scene slat lake has got a great one. my favorite is the salt city bandits. they've actually got a really cool website too www.localbeer.com. I don't know how they came up with that but it was easy for me to remember after being at one of their shows and swimming in booze!
this is pretty sweet, I actually saw a sticker somewhere in Salt Lake for this site. It'd be cool if the mountain update section got updated by all the resorts who where signed up.
