NEXT MEETING: Wednesday, April 16, 2025, 6:00 PM at 2045 Memory Lane in Silver City, New Mexico. The GCAS's next monthly IN-PERSON ONLY meeting features speaker geoarchaeologist Dave Rachal PhD of Tierra Vieja Consulting in Las Cruces NM. Doors open at 6:00 PM with light refreshments on offer. Socializing and a brief-to-nonexistent business meeting will immediately precede Dave's presentation of: How Did The Seeds Get There? Ruppia cirrhosa Ecology, Depositional Context and Accurate Radiocarbon Dating at White Sands: "The stratigraphic and geomorphic contexts, and ultimately the chronometric determinations, at White Sands Locality-2 (WHSA-2) are topics of controversy that stem from conflicting interpretations of the processes that deposited the Ruppia cirrhosa (Ruppia) seeds within the paleo-Lake Otero footprint site....[O]ur interpretation depicts the shoreline as an unstable, dynamic lake margin to which Ruppia seeds...were transported from deep-water, offshore growth beds during storm events and deposited on the lake shore in seed balls. These unusual aggregates, known to mix seeds of wide-ranging ages, were gradually broken apart by several cycles of wave action and erosion and redeposited in layers....[W]e will delve into both the ecology and the depositional context of Ruppia and discuss why the Ruppia seeds at paleo-Lake Otero are problematic materials for radiocarbon dating." Check out Dave's and Tierra Vieja Consulting's YouTube videos (links are on our Events page) and bring your questions for him!

Last Call to Join an International Archaeological Tour

Generic flightThe Jornada Research Institute is offering its final archaeologically-flavored international tour of 2024: enjoy an 11-day tour of Greece and Ephesus, Turkey this coming October. Sign up now while space is still available.

OF SPECIAL INTEREST TO GCAS MEMBERS, JRI can donate to other nonprofit organizations whose member participates in one or more of their Overseas Journeys Programs. So, for example, JRI will donate $125.00 to the Grant County Archaeological Society for each tour participant who specifies that the GCAS should receive JRI's donation. Join a JRI tour, and support two nonprofits at once!

The JRI's President, Dave Greenwald, further describes this tour:

…Our overseas tours are heavily focused on archaeology and history. We offer these tours through our Overseas Journeys Program as part of our continuing education where we make learning awesome. The Overseas Journeys Program is also an important fund raiser to help us cover the costs of continuing excavations and analyses on the sites we are currently investigating in New Mexico....Our tours typically consist of comprehensive daily activities, designed for active people, and include professional guides with specific knowledge of each area....

...From October 7 to 17, we will explore Greece, with a stop at Ephesus, Turkey. This tour is a combined land tour and cruise. Prices include airfare as an option and 20 meals. The minimum number of participants is 15. We began advertising this tour last month (May 2023) and have 6 participants so far….
