I have a semi-official gut pile at my place for past 20+ years. It's away from the camp and it's where we discard all the guts and anything else we dump after cleaning an animal. On an average year we dump remains of 3 deer and 15 hogs at this spot so you can find lots of bones around it. Oh yeah, it's also our coyote hunting spot so there are plenty of coyote bones too.
