USING GROUND PENETRATING RADAR (GPR) TO FIND PLEISTOCENE MEGAFAUNA FOSSILS AT THE HISCOCK SITE IN WESTERN NEW YORK
The GPR system used is the PulseEkko 100, equipped with 50, 100, and 200 MHz antennae. Over 130 profiles were taken at the site with a dual purpose: to locate subsurface anomalies on the site and to identify the presence of the fossil-bearing layer in the hills surrounding the site's previous excavation pits. Stratigraphic reflectors are located at depths up to 4 m at 100 MHz and 6 m at 50 MHz. The integration of radar profiles with known stratigraphic data from previously excavated pits is used to generate a fairly reliable 3-D image of the subsurface that would be suitable to aid paleontologists in future excavations. Detailed examination of the fossil bearing layer in profile view may also yield the exact location of radar anomalies thought to be bones. Future excavations at the site will be used to confirm or refute these interpretations.
