This was done as a control study at the end of the GPR Study. We had been surveying an approximately 75 square meter area down the hillside trying to plot the course of the trench. Grid 12 was an area at the top of the hill where the trench had been fully excavated in previous seasons. While the geology was somewhat different at the top of the hill, and while the excavation itself would alter the GPR results, we still believed we could get a sub-surface signature of the trench in an area where we knew it was located. In post-processing, we did find this signature to reappear in the areas where the trench seemed to be located.
