The waptus suggestion is kinda out of your prior description. Waptus is 10 miles and you aren't at the hunting when you get there, you're a ways off. So if you have 10 miles as a base line you've opened up 75% of the wilderness.
Prepare for wet. Boots should be waterproof. Solid rain gear. Wet sack for your interior pack area or a combo that will suit as a pack cover. Tarp aside from your tent so that if you are stuck in a bad situation you have an emergency shelter. Bag should have a water repellent surface, a bivy to put around it or both.
Bring less food than you think. It's weight expensive and I never eat what I think I will. If you want solitude, stay away from lakes or heads of basins with trails leading to them, and any obvious and easy to reach side basins of same. Plan around water, running out of it sucks.
Consider being very spartan and mobile. A lot of country is walked right by. That doesn't mean no game it means it doesn't give wide big expanses and so it's overlooked. Some trail systems will provide a series of small pocket basins that you can try. Because they have no obvious camp sites, no huge expanse, no lake and no trail to their front door you can likely find a number of such places on your map. If you don't see deer, all that means is you don't see em, they may be there, be patient. Have low expectations. Have high spirits. Have adventure.
