  • Fee: $60 JTNPA member, $70 non member
  • Instructor: Daniel McCarthy, M.S., Anthropology

Intaglios or large figures laid out on the ground are one of the unsolved mysteries of modern Archaeology. Officially classified as a form of rock art, there are over 300 intaglios in the American Southwest and Mexico. Daniel McCarthy will lead this all-day field class to three sites to explore these larger than life images preserved on the desert floor. The best known of these are the Blythe Intaglios along the Colorado River that are famous for multiple human-like figures. The largest human figure is 240 feet in length! Participants will learn about these “gravel pictographs” and their significance. This is a great opportunity to visit these immense drawings with an expert archaeologist. Participants will drive 230 miles (round trip) during the class, from Twentynine Palms to just north of Blythe where the class will finish. Carpooling is encouraged.

1:00 – Jon Erlandson, PhD, archaeologist, professor and director of the Museum of Natural & Cultural History (MNCH), University of Oregon who has worked on California’s Channel Islands for 40 years will discuss human evolution, the role of fishing and seafaring in human prehistory, and the peopling of the Americas.
