Ground Penetrating Radar Mapping


The 1936 cemetery researchers reported that the oldest grave was marked 1853. While that may have been true of graves with marked dates, we now know that the oldest burial in the cemetery probably occurred there prior to 1810, given what we know about the 1807 origin of the Big Fork Baptist Church with which the cemetery was identified.
One of the first major efforts in a renewed and enhanced plan to restore and preserve the historic Big Fork Cemetery was a Ground Penetrating Radar (GPR) mapping project (February 2023) to determine how many burials occurred in the cemetery and where those burials are located. In 1936, approximately 118 graves were thought to be in the cemetery. Between 1936 and 1965, some additional burials were conducted there but probably not nearly enough to make up the gap between 118 and the 179 discovered there prior to the 2023 GPR mapping. So, even in 1936 some of the older graves must have been undiscoverable by the WPA (Works Progress Administration) researchers. Thanks to ground penetrating radar, we now know the remains of at least 389 people are interred in the Big Fork Cemetery.
The Big Fork Historic Cemetery Corporation employed GPR expert, Len Strozier, President of Omega Mapping Services, to locate previously unknown burials in the cemetery and map the site. At the time Len mapped the Big Fork Cemetery in February 2023, he had already evaluated 900,000 burial spaces of which more than 175,000 unmarked burials were discovered, marked, and mapped.
