Heartfield, Price and Greene, Inc. of Monroe, Louisiana, was contracted by the United States Corps of Engineers, Mobile District to: a) conduct a cultural resources inventory of proposed dam and dry impoundment areas north of Ross Barnett Reservoir and, b) to conduct a cultural resources reconnaissance of the Pearl River, between River Mile 278 and 301, in the vicinity of Jackson, Mississippi. This report has collected and synthesized environmental, archeological, ethnographic, and historic data pertaining to the study area. The study revealed that almost no cultural resources research had been conducted within the dry impoundment area. Eight archeological sites had been recorded along the margins of the dry impoundment area. No information could be found concerning three 'Indian mounds' depicted on U.S.G.S. quad maps. Approximately 560 acres within the two proposed dam alignments and their associated spillways were surveyed. Nine locations of cultural resources (1 prehistoric site, 6 structures and 4 historic sites) were located. All are described. Approximately 837 acres were surveyed between River Miles 278 and 301. Five previously recorded sites were visited; two previously recorded sites could not be reached because of flooding. Six new cultural resource locations (5 structures and a historic site) were recorded.
