Asa is right. You can bury a carcass in a field in fall and in winter the canines or other furbearers will find it. Years ago i would take my skinned skunk carcasses minus the skunk glands and bury in fields in fall and come winter with snow covering also, the wolves, yotes and fox would find everyone. One time the yotes dug down thru a four foot deep snow bank to get to buried skunk.
