Great Hopewell Road

Results of magnetic survey;   Results of resistivity survey showing linear anomalies that may represent the earthen wall enclosures of the Great Hopewell Road;   Resistance data set with a profile line drawn the entire 100 m expanse;

Hopeton Works Enclosure (Hopewell Culture National Historical Park)

Line plot of magnetic susceptibility and elevation data;        

 

Johnson's Island (Confederate Stockade Cemetery)

GPR image showing a soil horizon that was used to identify disturbances that may indicate graves;   GPR image that exhibits a well-pronounced reflection that is likely an air-filled or metallic coffin at approximately 0.8 meters deep;   Interpretation of graves from survey. Red indicates possible coffin, blue-filled indicates well defined soil disturbance, and blue-unfilled indicates possible grave based on soil disturbance;

Kettering Shaker Cemetery

Conductivity image from the Kettering Shaker cemetery;   Magnetic image from the Kettering Shaker cemetery;    

P Street Mound

A conductivity profile across the P Street mound;   A resistivity sounding near the P Street mound;   A resistivity pseudosection at the P Street mound;

River Bank Stabilization Project (Hopewell Mound Group)

Magnetic gradient data from bank stabilization project area and outlined anomalies which are targets for future archaeological research.   Conductivity from band stabilization project.   Geophyscial data from grid unit 4.
Geophysical data from grid units 31 and 38.
