It is tough country with low elk/deer densities that can turn dangerous if you're not prepared. That being said, utilize the above information to set yourself up for success. I started hunting the unit two seasons ago with the same intentions of you, "get away from people, explore beautiful country, and enjoy the backcountry." I started getting discouraged about my tag choice after reviewing past threads with people claiming the country is impossible to hunt. That being said, in the last two years between my father and I, we have taken four bucks and three bulls out of the unit, on DIY non-guided hunts. Should have been four bulls but a miss occurred. We hunt hard, we go deep, we have horrible packouts, but we have a lot of fun and a lot of success.
My biggest two pieces of advice: 1) Be prepared to have your butt kicked by the terrain and/or the weather. 2) Make sure you have multiple areas picked out to hunt. If the elk aren't in an area, get out and try another because they are extremely spotty, but you can find them.
And come back and share your hunt on this thread.
