Ground penetrating radar (GPR) and Frequency-Domain Electromagnetic (FDEM) surveys were employed over an extensively modified 50 m x 65 m city lot containing a farmhouse initially constructed between 1786 and 1806 and a later barn. Both geophysical methods suggested that most of the lot had experienced substantial disturbance and that there was limited sub - surface preservation. Both the GPR and EM surveys indicated a scatter of metallic debris and other disturbance s in the back yard at depths up to 1 m. Most of the front yard also presents as disturbed, except for two unusual but limited buried surfaces that were identified in the GPR. Three 50 cm x 50 cm shovel test pits in these two areas confirmed the presence of preserved surfaces or at least archaeological deposits, under more than 65 cm of unremarkable fill.
