THE GRAND PARALLEL: A CONSISTENT LATITUDE OF LATE WOODLAND AND CADDO MULTIMOUND CENTERS IN THE LOWER MISSISSIPPI VALLEY AND EASTERN TEXAS

During the Late Woodland subperiod between A.D. 400 to 1200, six major multimound centers in eastern Texas and the Lower Mississippi Valley were established on a consistent latitude of 31.6 degrees north. The six sites comprising the pattern include, from west to east: George C. Davis and Washington Square in eastern Texas; Troyville, the Elkhorn/Frogmore/Churupa three-mound cluster, and Deprato in Louisiana; and Emerald Mound in Mississippi. Troyville, a major population center during the Baytown period from A.D. 400 to 700, is the earliest of the constituent sites. Emerald, among the latest sites, was apparently founded at the end of the Late Woodland or shortly thereafter. Several lines of evidence suggest the site distribution is not random. Rather, the pattern may reflect an emphasis on cardinal directions as a significant organizing principle in the layout of settlements, structures, burials, and other features in Caddo and Lower Mississippi Valley societies. This principle has rarely been noted on a macro-regional scale. I propose a hypothetical model of the sequence and processes by which the pattern formed. The model postulates that the same organizational principles operating at the site level also operated at the intersite and interregional level as mound centers were abandoned and new ones were established on socially sanctioned axes.
