The Adams Bay site (16PL08), located in the coastal marsh of Plaquemines Parish, Louisiana, is a precolonial mound site containing an earthen mound on the north edge of a plaza and a remnant mound on the southern edge. The layout of the mounds in cardinal directions around the plaza suggests that this component of the site dates to the Coles Creek period. On the eastern side of the site an extensive, wave-washed and re-deposited oyster (Crassostrea virginica) and rangia (Rangia cuneata) shell midden contains diagnostic Coles Creek, Plaquemine, and Mississippian pottery. Archaeological research at the site was conducted to confirm the cultural affiliation of the mound group and midden, and to assess the effects of natural and anthropogenic processes and their impacts to the site. Surface collection yielded 102 pottery sherds that were collected and analyzed. Cores were collected along the edges of the mound, the plaza, as well as the eastern and western limits of the site in order to identify in situ archaeological deposits. The results of this investigation produced data that will allow archaeologists to more accurately compare precolonial coastal Louisiana and inland regions. Furthermore, this research will aid in identifying the geological and anthropogenic environmental stressors threatening Louisiana’s coastal archaeological sites.

The author wishes to thank Richie Blink, the Plaquemines Parish Outreach Coordinator, for without his time, energy, thoughtfulness, and most importantly his boat, this project never would have been possible. The author is also indebted to Brian Ostahowski, who offered insight into the problems facing many of coastal Louisiana’s archaeological sites. The author wishes to express appreciation to Dr. Charles “Chip” McGimsey, the Louisiana State Archaeologist and Director with the Division of Archaeology, for his patient consideration and invaluable assistance. Dr. Rebecca Saunders and Beverly S. Nuschler from the Louisiana State University Department of Geography and Anthropology deserve special recognition for allowing me the use of their total station. Also, for his insights into the ceramic identification, the author would like to extend his gratitude to Richard A. Weinstein.
Thank you to my parents, Jeffrey and Beverly Hale, and my in-laws, Hoyt and Kay Sanders. And to my wife, Ashley Hale, for without her support, assistance, and encouragement none of this would have been possible.
