...You are going to be in the woods for, say a month! You have basic camping gear (Pack, tarp, fire, knife, cord, blanket or sleeping bag, etc.) You can only have one weapon.

I'd still opt for a Marlin 30/30, or maybe a lightweight bolt action carbine in 223Rem., both scoped of course, and with backup iron sights. Laminated or synthetic stock on the bolt action. Stainless steel on both if available (but not shiney).
Oh well, just my .02
