Integration of shallow geophysics, archaeology and archival photographs to reveal the past buried at Ingleside Plantation, Piedmont North Carolina (USA)

Abstract

Ground penetrating radar supported by electrical resistivity tomography and gradiometer surveys were used to map buildings and infrastructure documenting sequential property use by three generations of the Jacob Forney family who began as farmers in the backcountry of North Carolina and rose to prominence in government and industry within the Southeastern United States. At Ingleside, the antebellum plantation house has been preserved, and the adjacent property remains relatively undisturbed. Context for the geophysical surveys was provided by archival photographs, written accounts including monographs and newspaper articles, and an archaeological excavation of the stone hearth within the plantation's summer kitchen. The location of an early log home with a stone-lined cellar with ties to the Piedmont Campaign of the American Revolution (in 1781) was newly discovered. In addition, a historic road, kitchen garden, and the postholes from an early post-in-the-ground building were imaged within the subsurface. The external summer kitchen and privy are associated with the plantation house constructed in 1817. Several cesspool vaults of potential privies are ingrown with trees. The results of the geophysical surveys document the evolving land use within one family in the American South and can be connected to a specific event in history, a goal of historical archaeology.
