A TOWN AT THE CROSSROADS: SITE-WIDE GRADIOMETRY SURVEYING AND MAPPING AT OLD TOWN RIDGE SITE (3CG41) IN NORTHEASTERN ARKANSAS

Abstract

Gradiometry survey at the Old Town Ridge (3CG41) site, a stockaded Middle Mississippian period town in the central Mississippi River Valley of Arkansas, demonstrates the efficacy of a broad-coverage, site-encompassing remote sensing methodology for initial interpretation of intrasite organization and complexity. Site access, time constraints, deep plow furrows, and cotton plant “stubble” associated with ongoing agriculture at the site defer the efficient use of a site-wide multisensor prospection methodology. However, a gradiometry survey identified multiple anomalies consistent with prehistoric structures, earthworks, earthquake liquefaction, and other interpreted features encompassed within the remains of a 7-ha, rectangular enclosure. Aerial photography, topography, and preliminary archaeological ground truthing provided additional information for analysis and interpretation.
