One of the vexing problems with old cemeteries and historical sites is the difficulty of finding the locations of unmarked graves. In many cases, the desire is to locate the graves so that they may be identified and left undisturbed by new construction. To be sure, the locations may have been marked at one time with wooden or even stone markers. However, the ravages of time, weather, animals, vandals, and acid rain over the years may have removed all traces of those markers. Locating unmarked graves is also vitally important in solving murder cases.
Historically, the only method of finding unmarked graves has been to start digging – not a very practical solution. However, modern technology now allows cemetery associations, historical societies, family societies, genealogists, archaeologists, police departments, and others to identify the locations of buried bodies and other objects with no digging required.
