Very high frequency ground-penetrating radar (GPR) reflection data were collected and processed at Laetoli Site S, to connect an ancient hominid pathway that was uncovered in two excavations conducted in 2016. These footprints have been dated to about 3.6 million years ago and are likely those of Australopithecus afarensis. Profiles were collected 5 cm apart were frequency filtered to enhance specific wave frequencies of interest, and then manually interpreted using 2-D profile analysis. The depth to the prints was digitized and three-dimensional maps were produced, which display the still-buried prints between excavations. Artificial intelligence was used to compare models of…
