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.
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.

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.

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
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.
