Phase I Remote Sensing Marine Archeological Survey of North Prong in Schooner Bayou, Vermilion Parish, Louisiana
Abstract
A Phase I Marine Archeological Remote Sensing Survey was conducted along a segment of the North Prong in Schooner Bayou, Vermilion Parish, Louisiana in support of a proposed Bank Line Stabilization project. The project area is located in North Prong, between the Gulf Intracoastal Waterway (GIWW) and Schooner Bayou, north of the Schooner Bayou Control Structure. The proposed repair and maintenance project will require the dredging of the navigation channel in the GIWW, and the North Prong. In keeping with the New Orleans District's mission to preserve, document, and protect significant cultural resources, this magnetic and acoustic remote sensing survey was undertaken to locate potential archeological remains and in so doing, assist the USACE-NOD in satisfying its responsibilities under Section 106 of the National Historic Preservation Act of 1966, as amended. The survey area for this project consisted of one block representing approximately 517 total acres located alternately on both the right and left descending banks of the North Prong. In total, approximately 8.5 linear miles of river bottom were surveyed. The primary objectives of this study were to identify specific targets that might represent significant submerged cultural resources within the project area, and to provide the USACE-NOD with management recommendations for such resources. These objectives were met with a research design that combined background archival investigations and a marine archeological remote sensing survey. In the analysis of magnetic data, particular attention was paid to those magnetic anomalies that comprise areas of high density, clusters of anomalies, and single anomalies of unusually high amplitude, duration, or those exhibiting complex magnetic signatures. A total of 51 individual magnetic anomalies were identified by this survey.
