Ground Penetrating Radar In The Search For Ancient Helike, Greece

The coastal city of Helike in Greece was destroyed by an earthquake in 373 BC and submerged in a<br>lagoon. The site was later silted over and reoccupied. Surveys in the area using ground penetrating radar<br>detected targets of potential archaeological interest. Exploratory trenches to investigate some targets<br>uncovered Byzantine, Roman and Hellenistic structures. However, the ruins of Classical and older<br>settlements, at 3 m depth and deeper, are probably beyond the range of radar in this area, due to the<br>prevalence ofconductingclay-rich lagoonalsediments.Herewediscuss theradar results,and briefly note<br>the identification of some radar targets by excavations.
