Case Study
Mission San Marcos
San Marcos Pueblo, New Mexico
The images below
show electrical resistance and magnetic field gradient data collected
over the site of the historic mission at Pueblo San Marcos. Use
the buttons to toggle between alternative data plots.
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.
