I have done some professional archaeology and it just does not seem practical on a battlefield. Even in places around here we dig up the plow zone with a bulldozer, but that could not be done on a battlefield because of the type of fill. I mean sure it is one thing if everything from that era is in one layer but with filling in holes and the newness of the sites you find plenty still on the surface, not like here where they dig up Cherokee artifacts.
