I haven't hunted that area and asking about a specific area and what the elk are doing at that time I doubt that you will get many replies but. I would believe that they are like they are in any other areas. If there is a lot of human activity such as deer hunts going on then they may move to a area that is harder to get to. But some things stays constant they need feed, water, and cover. It is quite possible that the area that you bow hunt may work in October. You may also see bulls in groups again since the rut is over except for some cows that will come into heat the second or third time to get bred.
If it was me I would find a high location that I could glass a lot of area to find them and then plan accordinly.
One of the things I struggle with when afield is keeping my rifle clean and in good working order. Small amounts of dust and dirt collect moisture; moisture can freeze rendering your action immovable when you need it most. I have seen this happen on multiple occasions, and over time, I’ve learned the cause and how to prevent this from happening.
The first thing that you need to avoid before going afield is leaving excess oil on the gun. Oil will trap dirt and sand in all the wrong places....
