The results of the electromagnetic conductivity survey covered an area
of approximately 16,600 m2, and required nearly 33,200
measurements. Cultural features, nearly a meter deep, tend to exhibit
low conductivity, due to differing electrical properties of the eolian
sediments that in-filled house and fortification depressions after the
site's abandonment. Note the reversal of the gray scale in this image
(conductivity is the inverse of resistivity): large measurements are
displayed in white or near-white.
The sharp line near the southern part of the village
is the Army Corps of Engineers protective berm created as part of a bank
stabilization program to protect this site from further erosion from
Lake Sharpe. A portion of the northwest quadrant of this village was
not surveyed by conductivity methods owing to the presence of a steel
wire and post fence which profoundly effects soil conductivity
measurements. For further discussion, see
"Interpretations."
This project was supported by a technology transfer grant from the National
Center for Preservation Technology and Training, National Park Service.
