The research plan for the site called for test excavation of several house features in different areas of the site, in order to test the hypothesis, (based on surface collection) that there was differential distribution of luxury goods across the site, an indication of social stratification. Two areas in the outlying east and north portions of the site were surveyed during the 2000 field season to locate features for excavation to test this hypothesis.

Combined Magnetic and Resistance Data

Above: This image shows combined resistance and magnetic data. The magnetic data is overlaid as colored contours on the grayscale resistance map. The combined resistance and magnetic anomalies centered at N17/E67 were selected for further investigation. Ground penetrating radar (GPR) was used to collect data over the area outlined in blue.

GPR Data

Left: The GPR time slice plot (a horizontal planview isolating specific depths) shows a circular anomaly coinciding with the resistance and magnetic anomaly. Coring was also used to confirm the identity of this house feature, which was then excavated.

 

Magnetic Survey Data

Above: Because of unusually dry conditions, resistance data was not collected over this area. The roughly circular magnetic high in the center of the survey area (N30/E30) was thought to represent a house. This was confirmed by coring, and was subsequently excavated.

Several other anomalies of interest appear in this area, including some that are analogous to the anomaly associated with the hearth in Feature 2000-1 (below).

Feature 2000-1

Feature 2000-1

Above:When excavated, the origin of this magnetic anomaly proved to be a feature containing a hearth and a concentration of fire-altered rock.

The anomaly is caused by remanent magnetization and enhanced magnetic susceptibility of the fire-altered minerals.

Data collected over this feature was used for comparative purposes.
