THE DELAWARE AND SUSQUEHANNA RIVER: A HISTORICAL AND ARCHAEOLOGICAL INVESTIGATION TO ANALYZE THE POTENTIAL PRESENCE OF SUBMERGED CULTURAL RESOURCES.
(Under the direction of Professor William Still) 1985.
The purpose of this study was to provide the Pennsylvania Historical and Museum Commission with an historical overview that traces the development of all maritime activity in the Delaware and Susquehanna River Basins. Activities such as settlers, shipbuilding, shipping, naval activity, ferry crossings, shipwrecks and dredging/shoreline filling were documented. This information, along with data compiled for an environmental assessment of the rivers, was used to create a preliminary sensitivity model which provided a ranking system. The ranking model judged portions of the rivers according to their perceived potential to yield submerged cultural resources in conjunction with the threat posed by disruptive activity. A generalized designation of High, Medium, Low-Medium and Low was accordingly assigned to each portion of the rivers.
An integral aspect of the project was the completion of an "on-site" investigation in portions of the Delaware River that were deemed highly sensitive. Nine specific areas were targeted for investigation. Within a total of eight field days, a remote sensing reconnaissance, utilizing a proton procession magnetometer, and limited dives were carried out during two separate work periods during the summer of 1984. The magnetometer reconnaissance produced a total of thirty-nine substantial magnetic targets or target clusters. Derelict vessels, visible shipwrecks and submerged shipwrecks in the work areas were inventoried. The position and coordinates of all targets and sites were plotted on work area maps, which were included in the On-Site Investigation Summary. Also included in the summary were the designated target numbers, description of magnetic signatures or resource types, remarks, and sketches of the submerged shipwreck site and diagnostic artifacts which were recovered from it.
