Well, Moab will be very hot in August. I would try to start your ride as early as possible - like 4-5am. You're going to get lots of opinions, but I would recommend Soverign Trail or Amassa Back to get a taste of Moab with out a shuttle. You could also ride slickrock - its very unique - but I'd prob do one of the first two.
Durango has a lot of great riding right by Ft. Lewis, but it will again be kind of hot. Best riding near town is prob a section of the Colorado Trail - you can hit it from town. If your rents don't mind dropping you Hermosa Creek is a classic.
Gunnison is 40 minutes from Crested Butte - one of my personal fav's. I'd check out Deadman's gulch (in between gunny and CB), or 401 if you only have a day. You could also ride Hartman rocks in Gunny - but (broken record) it will prob be fairly hot.
Pocatello is totally undiscovered. There is some excellent riding there but no guidebooks. They have a local xc ski map that is pretty useful if you get some beta from one of the bike shops. Easiest ride to find is the Prison Loop right behind the LDS church. Its a fun ride with some options and everybody knows where it is. There are lots of great rides there but it takes some time to figure out where they are (they're not signed). The town is pretty small, but I like it.
Hope that helps.
