when they were culturally acceptable and legal. Federal laws now prohibit archaeological work without permit on Federal property. Cambron and Hulse embarked on five excavations on the Quad site as the water levels allowed, reporting only on the findings from the westernmost test at the Circle of Rocks, completed in early 1960. This area was chosen because of the number of fluted points discovered in surface collections made by Frank Soday, and later inventories indicate that 21 fluted projectiles were discovered by the group within the boundaries of this scatter. During the Circle of Rocks excavation, twenty-one 5-foot square sections were taken down in arbitrary 3-inch levels to determine the stratigraphy of the site and the depth of the culture bearing deposit. Four distinct strata were encountered in the study, the first being a shallow layer of silt, the second a sterile vein of grayish clay that produced a combined total of only 8 artifacts. Stratum III was the first significant culture bearing layer and was encountered at a depth of 6 inches. Stratum IV was yellow clay that was considered sterile below 3 inches, based on findings of Cumberland and Clovis points weathering out of the bottom of Stratum III or the top of Stratum IV during a surface collection of the vicinity. While the midden was quite mixed, one fluted midsection was recovered from Stratum IV, as well as Dalton points, numerous scrapers, and one side notched projectile – a Big Sandy. Concentrations of Big Sandy points caused the researchers to suggest that the Quad site was perhaps a staging area for the Big Sandy (side-notched) culture in Alabama. Advancing this idea were the inventories by Hulse and Wright, which counted a total of 3,102 Big Sandys from the complex, 527 of which were discovered at the Circle of Rocks, and an additional 172 from the Stone Pipe Site. Hulse went on to suggest a greater antiquity of this type in the Tennessee Valley than believed, based on increases in the number of triangular and rectangular uniface end scrapers, thought to relate to Dalton or earlier types, in Big Sandy assemblages, and because all but 13 of the Big Sandys inventoried from the Quad Complex exhibited basal grinding, a trait suggesting some contemporaneity to "older" groups. The second excavation, which took place on the first levee away from the current river channel, became known as the Power Line
