ABSTRACT
This chapter discusses the range of features visible using GPR at prehistoric sites. It attempts to include studies of some of the features that had success with, which will give perhaps some general examples of how GPR interpretations have been useful in prehistoric sites. Only targeted excavations in the areas delineated by GPR can begin to test the ideas generated with the images presented. A grid for the collection of GPR profiles was set up, with almost every profile starting and stopping at different locations within the coordinate system, making for complex note taking and data processing later on. It takes a while to train one's eye to pay attention to the areas of no reflection on amplitude maps, as most GPR interpreters are accustomed to identifying the higher-amplitude reflections. Walls, often associated with floors, are commonly visible in GPR images, especially if they were constructed from stone or other reflective materials.
