Country,

These guys have hit major points. Knowing that you can get around without being lost is a major comfort and you can spend your time looking for animals more than your back trail.

I don't use a gps myself, but i'm not saying its a bad thing. But if you do use gps's do yourself a favor if you already don't own one. Buy it earlier and play with it and get to know how to use it well at home. And like elkamp said have it preprogram for area your going into. When you get to your area do some waypoint checks at camp before you ever set foot in the mountains for hunting. We have so many hunters lost everyyear due batteries and mess up's on the gps settings.
I prefer the compass and a topo but that's the military in me.

Main thing I would get for the trip would be some high altitude sickness pills and bring lots of water on your trip. Beer is fine but it usually makes people from lower elevation really sick at times and ruins the whole trip. Stick with the water you'll have a better time getting up those hills.

Its a pain in the butt but keep your food away from your sleeping area atleast 50ft incase a bear visit your camp. If you kill then keep those bloody clothes away from where you sleep also. Just to be safe.

If you don't walk much I would start now mile or two a day will make a big difference in your mobility in the mountains. Stick to a game plan for the day and let your hunting partners know roughly where you maybe in the event of an accident.

hey goodluck and have the time of your life. bring back some pics
