Earthwalk Press publishes North and South maps for the Wind River Range at 1:48000 scale, with trails. (Hopefully these cover the area you want; I don't have them, so I'm not sure.)
If you are going off-trail, you'll want quads. You can get them for $1/ea. from TOPO! Explorer (the application can download the quads you buy, and print) at:
Or you can get quads for the entire US for free from the Libre Map Project.
Organizing and printing these can be a pain, but, hey, they're free!
