If I could, I'd move up that direction myself. But other ties keep me where I am--in the Kansas City area. <sigh> Not exactly a mecca of wilderness. Anyhow....
As for suggestions for gear, I guess I'd start with the following:
Tent/shelter: Sturdy, reliable. If you consider going into the backcountry during the spring or fall, think about a four-season tent. I've been dumped on inside a three-season a few times, and done fine, but there've been a couple times where I'd have liked to have the added sureness of a bomb-proof tent.
Sleeping bag: A comfortable, warm one. A min. of a 20 deg bag is a must, and I usually carry a 0-5 deg down bag. One can always throw some off, but it's hard to add insulation.
Clothing: The layer principle. I always have a good fleece and something waterproof, along with at least mid-weight base available. And the best socks I can afford, with liners.
Boots: You have the idea, I'm sure.
First aid: The usual backcountry supplies. (When going into the backcountry for more than a week, I often carry along a bottle of a good broad-spectrum antibiotic. Talk to a well-informed doc about what might be a good choice.
Bear spray: A must, I now believe. Fifteen years ago, I didn't believe in the stuff, but I've become persuaded this is the best option for protection from a bear with whom you're having territorial or food-supply issues. And make sure you know how to use it.
Water filtration/treatment system. One that you know works, and with which you're comfortable. Even in the farthest backcountry, it's always safest to treat/filter water.
Survival kit: The ingredients of this sort of thing vary from person to person, but the idea itself is important. And always keep it at hand. Mine includes compass, flint/steel & fire starter, space blanket bivy, whistle, small knife, fishing line, hooks, & leaders, 60 ft nylon cord, small flashlight.
Firearms are not allowed in Nat. Parks. In backcountry outside the parks, they're of value only to those both willing and able to use them if need arises. I'll leave the rest of that to others to debate.
Final note: There are now options for carrying (at a price) personal locator beacons (PLBs) or devices like the SPOT, which allows one to send one of three-four canned messages to pre-determined email addresses or, in one case, essentially a 911 call. All done via satellite, with GPS coordinates sent for emergency calls. I don't yet carry one, but have seriously considered same. Cost is about $300 and up, but cheap if disaster strikes, I suppose.
That reminds me: It is vital that someone trustworthy be supplied with a clearly marked map of course/itinerary so that if you don't arrive when/where you should, help knows where to look.
Sorry if some of that is preaching to the choir. Kinda hard to know where to start/stop with that sort of thing.
Oh, by the way: Up in Montana, they call it "Big Sky Country". ;)
