bug spray, lots of bug spray. There are lots of good options here about this sort of thing I am not sure why I am posting, but sometimes its fun to pretend to know something. I wasn't sure if you were packing water, but a water purifier would be fine. There are lots of little streams and stuff in the Big Horns, but cows like them, too. So no raw water. Being hydrated is a huge concern with the exercise and the altitude, you really have to watch out. You need lots of calories, too. For the food make sure the dehydrated food has a lot of protein, not just noodles. I think there are a lot of package meals made especially for backpackers. Those magnesium fire starters are kindof fun, I think they work pretty well. There can be fire restrictions, so watch out for those as the time comes up. I personally don't like lighters because I keep burning my fingers. Lighting a candle with a lighter works for me I guess, so bring a lighter and some candles. Extra socks and clothes are a must. Bring clothes for cold, snow, and wet just in case at any time of year. With my kid in Boy Scouts, I kindof cheat and just go down their checklist. Compass, GPS, maps, hatchet, a couple good knives, sharpener, cook stove, my list seems to get bigger all the time. Those are probably part of your normal hunting gear. There are some pretty light weight tents and sleeping bags, and there is a thread here about floorless tarp tents or some such thing. Good to look into. You might be looking at a 50# pack with a weeks worth of stuff, so no extras. 50# is a lot for me for longer distances, at least its downhill on the way back. Those Wal-Mart sleeping bags rated for +40 might not cut it, it can get a little chilly at times. Well have fun. Hope you get some good info from these guys. Oh bear bag, rope, and spray, almost forgot.
