How to Map Unmarked Graves in Cemeteries
Have the Graves in Your Cemetery Located by a Nationally Recognized Expert with over 20 Years of Experience
Some cemeteries are hundreds of years old and unmarked graves can be common. Misplaced or poorly located headstones or markers can further complicate matters.
Records are often vague, lost, destroyed, or incomplete and there may be questions about the precise extent of a cemetery. There is often no surface expression of the burial location and graves become lost.
Due to the sensitivity of these sites, the challenge is to explore the subsurface without disturbing the soil and burials. Ground Penetrating Radar (GPR) is the only viable non-destructive method used for grave detection.
Ground Penetrating Radar (GPR) cemetery surveys are non-intrusive and ideal for locating cemeteries and for unmarked grave detection. GeoModel uses GPR to detect a number of features that help identify a grave, including:
- The coffin or casket (wood, metal, lead lined, etc) or vault
- Disturbed ground structure and excavation features
- Movement or voids caused by collapse of the coffin or casket
Recently, GeoModel, Inc. carried out a grave detection scan at the Gallatin City Cemetery in Gallatin, Tennessee, to locate lost graves. The survey was conducted in the older slave section to locate unmarked graves in order to identify and accurately mark the locations of each grave on the ground surface.
Hundreds of lost graves were detected in the 4-acre area that dates back to the 1800’s. The link to a video on NewsChannel5 is below, and an article in the Tennessean newspaper is further below.

How Accurate is Ground Penetrating Radar to Detect an Unmarked Grave for Cemetery Scanning?
Recent interments (1 to 50 years old) generally produce very distinct grave anomalies in the GPR profile and are most easily detected. Older graves (50 to 200 years old or more) produce less distinct or minimal anomalies and are more difficult to detect.
Remains of burials are easier to locate in sandy soils that do not contain tree roots or rocks.
In cases where a vault or casket does not exist, or where the casket has completely deteriorated, the trained eye of the GeoModel, Inc. professional can examine the GPR data for disturbed soil, grave trenches, or other indications of the burial.
Many cemeteries have unmarked gravesites, lost graves, old burials, and more recent burials, as shown in the ground penetrating radar image above from the historic Arlington Cemetery.
