  • Additional Analysis on GPR Mapping of the Hominid Trackway, Laetoli, Tanzania

    Previously I wrote a paper on the mapping of the hominid tracks at Laetoli Site S, which connected the trackway from two excavations conducted in 2016. In the search for other tracks in other grids, I mapped other features that are not footprints, but could be confused with them. This short paper is that analysis,…

  • GPR at Laetoli, Tanzania: Micro GPR for mapping hominid footprints

    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…
