Good advice from swampcruiser. I'd recommend at least
10x, depending on the type of hunt. A few years back I tried
8x while hunting coues deer in Arizona, difficult to say the
least. I now own both 10 x 42 (Cabela's Alaskan Guide) for
hunting out west and 8 x 32 (Leica) for hunting here in the
midwest.

Unfortunately, good glass = $$$. It took several years
and some corner cutting elsewhere, but I'm very happy
with my binoculars now. If this is a one time hunt out
west, I'd be less inclined to spend a lot of money. IMO,
just as the 8x are not strong enough out west, I've found
the 10x are too strong (small field of view) for the terrain
(timber) I hunt here in the midwest.

Best of luck~
