I guess I should explain my elk and deer hunting to be similar. My first trip was with 2 other died in the wool eastern whitetail hunters who had never hunted or even seen a wild elk. We hunted DIY in south central Colorado and basically hunted the same way we hunt deer by still hunting. Perhaps it was luck or possibly providence but on day 2 I stumbled on a herd at first light and bagged my first elk a fat cow. That group of cows had some bulls that were bedded just over the rise and at my shot they all took off towards where my buddies were hunting a mile away. First one then about 5 minutes later another shot and when we got connected with our radios we discovered we all had one down. 2 Cows and a bull. The two animals are definitely way different but moving into the wind, going slow and using terrain to hide is the way we hunt deer and it worked well for elk at least for us. Following years we became a little more familiar with elk and the type of places they like and worked calling into the hunt. Deer are often alone and the area we hunt the elk at that time of the year are usually grouped up so there are a lot more eyes and ears on watch. I found elk were similar to deer in several ways. First of all their sense of smell is very good and with the changing western winds they definitely have an advantage. I feel their eyesight is good but what makes them harder to hunt than deer IMO is they aren't curious. Deer when jumped will often only run a short ways and might even stop and look back. Elk are long gone to the next county when jumped with one exception. We found that often when we jump some if they didn't really bust us a quick series of cow calls will settle them down and sometimes will actually stop them. I had a whole herd all around me on a steep hill in the dark timber and then they stopped and could see the bull coming over the edge down towards me and luckily the wind was calm. A spike bull was about 25 yards to the side from me and was looking my way knowing something was wrong. I was down in the snow on my knees crouched as low as I could go. A cow with calf just up hill started to bark and I knew the gig was up. Just for chits and grins I reached into my pocket and hit a hoochie mama and the whole herd just went back to walking down past me and then along came the bull. I am not an elk expert by any means but am a pretty good eastern deer hunter that brings some of that luck out west when I get the chance to use it.
And to the OP...your KC Cabelas is a good one that we have visited each year for the past 10 that we have gone out. The muley room is something to behold.
