CONTINUING THE RESEARCH: ARCHAEOGEOPHYSICAL INVESTIGATIONS AT THE BATTLE MOUND SITE (3LA1) IN LAFAYETTE COUNTY,ARKANSAS

Abstract

The continuing use of archaeogeophysical methods at the Battle Mound site (3LA1) exemplifies the power of geophysics as a non-invasive, preservation-oriented, and economically feasible way to pursue the exploration of settlement patterning at the Middle and Late Caddo (ca. A.D. 1200–1680) mound site. Using these methods, a 1-ha (2.47 acres) area directly east of the large mound was surveyed using magnetic gradiometry and concatenated to the existing survey area. Results from the 1-ha survey provide further elucidation of the spatial structure and internal organization of the Caddo Indian occupation at the Battle Mound site.     

TOM JONES (3HE40): GEOPHYSICAL SURVEY AND SPATIAL ORGANIZATION AT A CADDO MOUND SITE IN SOUTHWEST ARKANSAS

Abstract

This article outlines a process that has facilitated discoveries of intrasite pattern, architecture, and diagnostic artifacts at the prehistoric Caddo mound site Tom Jones (3HE40) in southwestern Arkansas. A methodology of multisensor geophysical survey using electrical resistance, electromagnetic conductivity, gradiometry, magnetic susceptibility, high accuracy survey and mapping, and data georeferencing enabled by geographic information system technology has proven to be an efficient, effective, and essential component of an overall research plan. In addition to providing insights regarding the intrasite organization of an upland Caddo ceremonial mound center, this technologically integrated approach has established that Saratoga chalk geology and Blackland Prairie clays combine to form an advantageous medium for geophysical discovery.     

MOUND BUILDING AT LAKE JACKSON (8LE1), TALLAHASSEE,FLORIDA: NEW INSIGHTS FROM GROUND PENETRATING RADAR

Abstract

The Lake Jackson Mounds site (8LE1), located near Tallahassee, Florida, has long been considered to be a frontier Mississippian center. This assertion is primarily based on elaborate burial goods recovered during salvage excavations in the 1970s. Ground penetrating radar (GPR) on the two largest intact mounds at Lake Jackson revealed new information about their morphology and construction histories. These findings demonstrate that mound-building practices at the site were distinct from earlier, local Woodland mound-building traditions, and more similar to those of other Mississippian centers, such as Etowah and Moundville. Lake Jackson revitalized mound building in the Tallahassee area under the influence of external connections with groups in the Mississippian interaction network. These findings show how mound building was an integral practice for expressing and expanding Mississippian ideologies and rituals. This work also shows the utility of GPR in exploring mounds' morphologies and construction histories.
