According to the Department of Environment and Natural Resources (DENR), there are more than 3000 located caves in the Philippines. Among these, only a few have been identified as of archaeological significance. This is in part due to problems determining whether a cave or rock shelter is likely to contain deposits of substantial depth, and/or of archaeological potential without undertaking expensive and time-consuming excavations. To address this problem, archaeologists in the Philippines are testing whether ground penetrating radar (GPR) is an effective technique in targeting buried geomorphological features such as rock fall and palaeochannels, and deposit depth within cave and rock shelter sites. The aim of this presentation is to outline a possible procedure using GPR to identify anomalies in caves, and to discuss a methodology that might aid the archaeologist in determining whether a cave has archaeological potential, which include determining what geomorphological features might be present below ground, and where the best locations within a cave or rock shelter might be for excavation.
