I loved Powder Mountain. We were there on a still, sunny cold day, a few days after a snowfall. It was a long drive - if you were to be skiing Snowbasin and Powder Mountain, I'd stay in Eden or even Ogden. Eden was nice though.
I didn't know about the helicopter, but we got 1 ticket for the Cat. Best of all though, we got a bloke from ski school to be our guide. Oh Boy! He took us straight up to the Cat, and to the top behind that, and then showed us the most amazing stuff out wide. We didn't come back into the resort for quite some time. We'd have never found this stuff on our own, or ventured out that way. It was all pristine, untouched, deep and awesome. He was an older guy who's been there for years, and he knew it all, every rock, every dip.
We found another wonderful area around the opposite side, paradise or something, again totally untouched, and it was so pretty.
For me, it was about deserted open powder skiing, exploring, and huge acerage, rather than steeps/gnarly etc. And mega-friendly people. I'd very much recommend hiring a guide from ski school. Do not miss Powder Mountain! (or snowbasin).
