Electrical Resistance Survey
Correlation between magnetic anomalies (blue) and resistance anomalies (red)
Numerous circular, rectangular, or square resistance highs (generally
in the red range of the color scale) are thought to represent semi-subterranean
pit house features. Most of these anomalies have a direct correlate
in the magnetic field gradient results. This correlation significantly
increases the degree of certainty of our interpretations.
A number of linear resistance anomalies (both high and low) appear in the data, particularly in the northern portion of the survey area, where less saturated soils were more favorable for resistance methods. These anomalies may represent the remains of structures external to houses such as corrals or stockades, or they may be natural in origin. Subsurface testing will allow more confident and detailed interpretation.
