As part of my Masters thesis, I'm currently testing ground-penetrating radar data that Kimberly Henderson collected during the 2002 field season. By integrating standard archaeological excavation with GPR technology, I hope to pinpoint areas to excavate that can potentially yield a great deal of information with relatively little site disturbance.

We're presently excavating six units west of the Akapana. The GPR map pictured below shows a 40 x 40 meter survey area sliced to 6-9 nanoseconds corresponding to a depth of approximately 30 to 45 centimeters. The black arrow points to a high amplitude reflection detected in the southwest corner of one of the six units. The photograph (left) is the southwest corner of the unit highlighted in the GPR map. It shows the reflection was created by a stone tile surface located 27 centimeters below the surface. Other units have also yielded architecture and features that correspond to GPR reflections.
