If you are looking for paper maps, which it sounds like you are I'd check these out. I've got a couple for Wyoming and I like them. Also, on the digital side of things, Onx maps is great!
Two trails illustrated maps cover every where except powder horn. I think the La Garitta map and Lake City/Telluride map. If you want Powder Horn you have to custom build a map or go USGS quads or digital.
I'll second Nat Geo or the DIYHunting Maps. I think the Nat Geo are some of the best you can get. The DIY are decent - depending on the scale. I found some of them a little too small for my liking.
