The Cahokia Connection at the Lake Providence Mounds, Louisiana
Several hundred potentially exotic sherds were recovered from late Coles Creek period (ca. A.D. 1150 to 1260) contexts at the Lake Providence Mounds in northeast Louisiana. A number of these sherds appeared to represent the remains of vessels from Cahokia or sites in the American Bottom region of southern Illinois, while others likely were local copies of Cahokia vessels. A selected sample of these “exotic” sherds, along with recognized local specimens, were subjected to petrographic thin sectioning (petrographic analysis) and instrumental neutron activation analysis (INAA). These analyses suggested that some of the potentially exotic sherds were, indeed, from the American Bottom area, while others could not be sources to a specific region. Possible reasons for the exotic vessels at Lake Providence are discussed.
