The GPR data were downloaded to a laptop computer and processed using GPR Slice software, produced by the Geophysical Archaeometry Laboratory. For each data set, twelve amplitude slice maps were created to a depth of approximately 110 cm. Because of the highly conductive soil, data below this depth were degraded and excluded from analysis. A hyperbola fit was performed on the data to allow the depth to be estimated. An overlay was constructed of all twelve slices to locate strong anomalies throughout the data. The raster data set was exported from GPR Slice to be included in a GIS, where anomalies were identified for three depth ranges: 0 – 30cm, 40 – 70cm, and 80 – 110cm. For the Whittington Site, amplitude slice maps are shown in Figure 3, the overlay shown in Figure 4, and anomalies are identified in Figure 5. For Ailhaud St. Anne, amplitude maps are shown in Figure 6, the overlay shown in Figure 7, and anomalies identified in Figure 8.
