Burnside Plantation Results

Laura Sherrod - 2016


Geophysical investigations were performed to provide subsurface images using a 400MHz GSSI SIR 3000 GPR system and a Geometrics G-858 magnetometer in gradiometer mode.  Lines were spaced at 2ft to provide complete coverage of the survey area.  Foundation stones should appear as hyperbolic reflections in the GPR profiles due to the discrete nature of the stone in the soil and the diffraction of the radar energy off the edges of the stones.  Several hyperbolic reflections were identified in the analysis of the GPR profiles, but plots of the locations of these reflections did not correspond to the general shape of a building.  Another category of GPR anomaly was observed at this site: a high amplitude, concave reflection.  The size of these anomalies may correspond to the approximate size of buildings, but conclusive interpretations are not possible with the geophysical data collected.  Excavation would be a potential next step.
