If you are in the field.woods and you come across what seems to be a shallow grave (maybe an old civil war grave), but not sure, what is the law concerning this whole issue. It could be a depression with (what seems to be) a rock for a marker, or a few sunken areas that look like old graves. Is it okay to dig and see? Is it okay to detect around them if you think they are graves? What is the whole deal with this kind of thing (the ethical process).
