The purpose of this thesis was to further study geophysical anomalies discovered and mapped by Shank (2013) at the Stevenson Cemetery, Greene County, Ohio, with the goal of delineating any resistivity anomaly possibly associated with suspected, but unmarked, burial sites. The previous study delineated geophysical anomalies using electromagnetic (EM), magnetic, and ground penetrating radar surveys, which were interpreted to represent unmarked burial sites. A hand-drawn map from the 1950’s shows a pattern of gravesites across this area, and three aligned subtle depressions are present at the surface in the study area. The focus of this study was to expand the …

This study focuses on northern Terre Haute, Indiana, where seven 2D seismic reflection time sections were collected by CountryMark and donated to Wright State University. Geologically, the area is on the eastern margin of the Illinois Basin. Two of these seismic lines display significant relief along a continuous, high-amplitude horizon approximately 180 milliseconds in two-way traveltime depth. This horizon was previously interpreted by CountryMark to be a Silurian reef core of the type common in this region of the Illinois Basin; however, other seismic lines within the data set display no relief. Furthermore, borehole logs within the area show no …
