Teton Wilderness

In addition to the replies you receive here I would also contact the Forest Service for that area

Buffalo Ranger District

They may be able to recommend some material and offer some opinions on the best backcountry opportunities within that particular wilderness.

Cheers

Googling came up with lots of trip reports, some probably worth looking at.

We have all become so spoiled with detailed guidebooks these days that we seem to have forgotten the era (not all that long ago!) when trips were planned using a not-very-detailed US Forest Service map plus USGS topo maps (usually 15-minute, not 7.5 minute) that showed the topography but often not the trails. Maybe it's time to put some adventure back into our trip planning and forget the guidebooks? Actually, if you want to be away from the crowds, it's a good idea to give the guidebook trails a miss and go elsewhere!

Sometimes it's more fun just to head out on a trail that looks interesting on the map and see where it leads.

I was there about a month ago. Great place. Once you are up higher you can get out of grizzly country and its less stressful.

Fly into jackson hole and hitchike in … way easier.

the main trails can kind of be packed until you get farther into the back country though.
