Underwater Remote Sensing Survey Dog River, Mobile County, Alabama

During the fall of 200, archaeologists from Panamerican Consultants, Inc PCI conducted remote-sensing investigations in the Dog River, Mobile County, Alabama, as part of the U.S. Army Corps of Engineers, Mobile Districts project entitled Underwater Remote Sensing Survey, Dog River, Mobile County, Alabama. Project plans call for the dredging of an area 100 feet wide in the center of the navigation channel. The project area consists of several corridors 100 feet in width and ranging in length from 500 feet to 8000 feet. The remote-sensing survey located seven anomalies in the project area. Of these seven anomalies, four did not meet the accepted criteria of 50 gamma strength over 80 feet duration. Two more met the criteria, but were close enough in proximity that they were treated as a single anomaly cluster rather than distinct individual anomalies. Finally, one anomaly had characteristics representative of a pipeline, but a historical records search revealed no known pipeline in the area of the anomaly. This anomaly and the aforementioned anomaly cluster are both recommended for further investigation via probing or diver inspection.
