those last three are elk hides. you can soak them and soften them up and see how they look. I don't know if you can tan them if the fat has soaked into the hide, i heard you cant, you will have to research that but i can tell you that here the local elks club collects hides for tanning and they usually stay in a pile for a month or more before taken away. BUT I'll warn you you need to call your game a fish department before moving them. Some states have laws against that sort of thing. If you get caught with a hide and you don't have proof , a license, of where you got it you could be in trouble.
