Summary

In American archaeology, ground-penetrating radar (GPR) has enjoyed its longest use in the Southwest. While this method has long been used to locate features of archaeological interest, much of the focus has now shifted from using this technique as a prospection tool to one that can be used directly in the study of archaeological sites. This reflects an increasing sophistication in the ways practitioners process, interpret, and visualize GPR data, which capitalizes on this method's high-resolution, three-dimensional mapping capabilities. Furthermore, combining these data with other geospatial techniques such as aerial photography and high resolution GPS survey means it is possible to associate buried features to surface phenomena, thereby opening up the types of questions that can be addressed while also preserving sensitive archaeological sites. This poster presentation draws upon examples from the American Southwest to show how this approach is being used to study sites in relation to the larger archaeological landscape. Far from being a simple prospection tool, the use of GPR in archaeology is enjoying a revitalization as advancements in the way geospatial methods are combined generate data that can be used directly in the interpretation of the archaeological record.
