Returning to the Kamp mound group (11C12): Results from geomagnetic survey and high-density topographic mapping in Calhoun county, Illinois

This article addresses the use of high-density topographic mapping and geo-magnetic fieldwork as part of an ongoing research program focused on evaluating the role of monumental architecture in the construction and maintenance of differing scales of community during Middle (ca. 50 cal B.C.-cal A.D. 400) and Late (ca. cal A.D. 400-1000) Woodland periods in the Lower Illinois River Valley. At the 2013 Center for American Archeology and Arizona State University field school, a 2.46-ha area at the Kamp Mound Group (11C12) containing Mounds 1, 6, 7, 8, and 9 was surveyed using magnetic fluxgate gradiometry and mapped using a high-density robotic total station. Our survey results demonstrate that highly disturbed mounds have significant interpretable structure that can be used as primary data to better understand spatial attributes related to evaluating site organization, distribution of activity areas in nonmounded space, and internal mound structure and composition.
