hey me again..thanks for the responses...I just got back from taking another look and didnt find any tracks or any sign of what could of done this. Did not see any signs of a den or anything of that sort. The mountain lion suggestion is interesting..I looked up so info on them and they do cache their kills..I have heard rumors of people seeing them in this area but at least 20 miles from where I found this. This part of Iowa is mainly wide open farm ground but we happen to own roughly 200 acres of woods in the area and thats where I found this..So I guess if there was a cat around it could hang up there for a while. I also walked through an 80 acre woods that connects with the one where the bone pile was found and saw 6 dead turkeys..I dont think this means much though. I have a cuddyback camera and plan on putting that up around that cache of bones in hopes of catching a glimpse of the culprit. If I find out anything I let you guys know..thanks
