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!
