metalback, one rear leg left attached(species) and some form of proof of sex must accompany the carcass. Deer the hides can not be left in the field so the hide rolled up is most common way or left on as few skin in the field. With bigger game such as moose or elk the head/antlers or lower jaw are most commonly kept by hunters. By way of the seperate seals or tags the DNR can cross reference carcass and hide to match up the harvests.
