The results of resistivity survey are presented graphically
as color image maps. Resistance values close to the mean are displayed
as shades of gray, the lighter shades representing areas of relatively
low resistivity and the darker shades representing areas of relatively
high resistivity. Areas of extremely high and low resistivity
are shown in color. This allows the values near the mean to be
displayed with greater contrast, revealing more subtle detail
than if the entire range of data were shown in grayscale.
Anomalies of interest are outlined on the map, and
discussed in descending order of precedence below.
1. A series of linear high resistance anomalies,
many of which form rectangular features are outlined in purple.
This region of rectangular anomalies is located between 80E and
120E. Remains of architectural features may be the source of these
anomalies, possibly buildings related to the iron works such as
worker housing.
2. A distinct linear resistance high centered at
40N, 60E is also outlined in purple. This linear anomaly may also
be related to linear archaeological or architectural features
associated with the iron works.
3. Two distinct parallel linear anomalies centered
at 26N, 77E are outlined in light blue. These linear anomalies
are well defined and have spatial correlation with linear magnetic
anomalies discussed below. The source of these anomalies may be
linear archaeological features.
There are also numerous, less distinct, linear resistance anomalies
present in the resistance data that were not outlined, particularly
in the area between 10E and 40E. Any of these linear anomalies
may be associated with archaeological features. A dam, which can
be seen on the banks and in the bed of the creek, may extend south
across the terrace. Although it does not appear distinctly in
the resistance data, this might be the origin of some of these
resistance anomalies. They might also be of geologic origin or
due to modern earth moving or other activities. The extremely
high resistivity values seen throughout the northern edge of the
survey area appear to be due to changes in moisture content associated
with variations in soil type and degree of soil consolidation.
