Resistance and magnetic data sets are shown with alternative processing and display parameters to enhance different aspects of cultural patterning. Subsurface architectural features are clearly visible in both data sets. Rather than being redundant, the two data sets complement one another. Because these two methods measure different physical properties, each method is able to define features that are not apparent in the other. Adobe walls appear as diffuse low-resistance rectilinear patterning in the resistance data. Stone foundations in the supporting walls appear as magnetic anomalies.
