If you don't go with a guide your best bet would be to hunt the back side of the Uinta Mountains coming in threw Evanston,Wy. I've hunted Elk up there a few times and ran into tons of Moose and some huge bulls.
I've talked with brian about this area. It's not a hard area to hunt. But it is wilderness.Most of it being remote. Your chances of seeing a big bull from a road is not good. Oh course it's possible, but not a high probability. You need to travel up the various drainages and look for moose. Most of the drainages have good trails that follow the rivers up the drainage. Prime areas to spot moose. You will almost always spot a few moose in each drainage. The trick is to look at enough bulls to find a nice trophy. This is where horses help. They allow you to cover more ground, to look at more animals. Of course packing a moose out on your back is serious work and pack horses make it much easier.
I ride horses in this area every August and September. We see plenty of moose and I'm confident that he can find a nice bull. I helped a good friends son harvest a moose last year in this area. I can tell him where to hunt. What he needs help with, is finding somebody that has horses to help him get into the various drainages and when successful help pack it out. Or a couple of able bodies to join him, lend some extra eyes, and help with the work. I drew a LE Elk tag and will be hunting in Central Utah during September or I'd help.
if you know a guide with a guide permit for this area let him know. If you horses and would like to spend later part of Sept on the North Slope, let him know.
There can be too much of a good thing with antler rattling.
I like to hit the horns together for a good 30- to 40-second rattling sequence and then hang them up and resist the urge to hit them again.
This works to the hunter's advantage, because if a buck has heard it, he may have been 300 or 400 yards away and he comes in and he's not exactly sure where it came from.
When finally is time to rattle again throw a slight change-up into the routine.
The second time, don't rattle as loud...
