The Phase I investigation of this property was an archaeological identification survey located within the Cape Cod National Seashore (CACO), Barnstable County, Massachusetts. The purpose was to determine the presence, nature, and extent of archaeological resources within the core area of the recently-acquired property, in order to allow park managers to plan future upgrades/repairs and public accessibility with a consideration to the potential impacts to archaeological resources. The project was conducted under contract with the National Park Service (NPS), which manages CACO. The focus of the archaeological survey was the area surrounding the Main House (c.1795) and several outbuildings, which were constructed or moved to the property between 1937 and 1947. The Phase I survey revealed a potentially significant prehistoric base camp that was used from the Late Archaic through Late Woodland periods.
