Who Gnows? Season 2 Episode 1 Apple Podcast by Matthew Smith
What can a structural geologist teach us about the formation of mountains, Nasca lines, and lost Raritan & Ethiopian ruins in New Jersey?  Recorded November 9 2020.

Geological explanation of the Nasca Lines, Peru RVCC Science-Seminar Series
The unique tectonic setting of this site in the Andes Mountain chain is depicted virtually using Google Earth to show how the geologic strata are naturally arranged to funnel, store, and discharge surface and shallow ground water into springs that were discovered, then augmented to supply desert fields with the precious water needed to sustain a growing, prehistoric culture. The complex patchwork of features is shown to be systematic with respect to water running downhill, and their relative time of formation and utility will be discussed in light of applying historical geological principles to solve the Nasca-line riddle.  Recorded February 24, 2020.

Plate Tectonic Actualism; Far-field Lithospheric Strains from Large-bolide Impacts  RVCC Science-Seminar Series. Recorded February 11, 2019
