Today we interview a recent PhD Graduate from the University of Santa Cruz that is now the project archaeologist for the Mesa Prieta New Mexico Petroglyph Project. We review Dr. Chester Liwosz's background and his recent research and then converse on indexical animals, archaeoacoustics, and the connections with Mesoamerica as recognized in the rock art of eastern California and the American Southwest. Interested in learning about how to use X-Rays and similar technology in archaeology? Check out the linked PaleoImaging course from James Elliot!
