Gore Place is the early 19th-century house and estate of Massachusetts governor Christopher Gore and his wife Rebecca. The Gores were active in scientific agriculture and cultivated grains, fruits, and vegetables on the property. As part of the landscape restoration, the Gore Place Society wished to know the exact location and preservation status of Gore’s stable and greenhouse. To determine these, we recursively combined historic map georeferencing, ground penetrating radar (GPR) survey, and excavation. We used an initial GPR survey to guide our excavation, then using the GPR-slice images and data from the excavations, a series of historical maps were re-georeferenced, allowing for much better interpretation of the GPR-slice images. Interpreting GPR, excavation, and documentary data in this integrated, sequential package yields more information with less excavation than traditional methods.
