Had an archery elk tag this year. Hope you hired an outfitter and/or have access to private land. There is a darn good reason why Coloradoboy and others rightly advocate hiring an outfitter in this unit. There are obviously some amount of really big bulls in this Unit to justify the $15k price tag for an outfitted hunt on private ground there. You can scroll thru the outfitter pages and see some pics of really nice bulls taken there. That said, the public ground on the west side of the Unit is rough pinyon and oakbrush winter range and the elk may or may not filter in there during your hunting season. The National Forest is so close to GJ and relatively small(roughly 3 miles by 4 miles) that the locals there have it figured out if there are any big bulls on that ground and where they are wwwaaayyy before the archery opener. Muzzleloader deer and elk hunters do a pretty good job of pushing the remaining elk on to the surrounding private. Couple that with every camper, mountain biker, hiker and who knows who else who rightfully use that ground as well and it's not the best setup for the public land elk hunter.
The private ground to the south and west of the National Forest is some of the prettiest elk and deer habitat I've ever seen and I have hunted deer and elk in CO for over 35 years. I did have three shot opportunities at small bulls that I passed on - hoping to find one of the larger bulls that may have wandered onto the public. I believe the older bulls have the gig figured out - I heard very little bugling on public but absolute bugling chaos 3-400 yards across the fencelines on the private. Hunters would walk the fencelines and call to those bulls with absolutely no luck in persuading the herd bulls to come and cross the fences. The calling might be effective if you had the opportunity to advance on the bulls but the fenceline ends the game. The 3 bulls I had shot opportunities at were obviously satellite bulls with no cows.
You might want to consider a bear tag - I had a tag and walked up right behind one ambling down the same trail I was walking very early one morning. I got a little unnerved by the encounter and I never considered killing it and was happy to freeze on the trail and let it put some distance between us.
All this being said, if you're out there giving it your best shot, anything can happen and you may see the biggest darn bull in the Unit on public ground and anchor him. Best of luck to you and I hope you have an enjoyable hunt, make some memories and harvest a monster bull. I am more than happy to answer any questions you may have if I am able because this was a one and done hunt for me and this Unit.
