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!

For those unfamiliar with Old Pueblo Archaeology Center [photo on right via OPAC], it is an organization headquartered in Tucson, Arizona, devoted to education and preservation of historic and archaeological sites and artifacts throughout the region of the US Southwest and Mexico Northwest. They serve as a clearinghouse for events, tours, educational programs, and volunteer opportunities for individuals including students of all ages, professionals, and interested nonprofessionals.

Early next year, Old Pueblo will present a day trip that may be of particular interest to those of us in the Grant County, New Mexico area. Their "Cave Creek Canyon Pictographs Tour" will happen on January 25, 2020, from 10:00 AM to 4:00 PM. The trip will be led by archaeologist Kelsey Hanson starting at the Chiricahua Desert Museum located at the US-80 & NM-533 (Portal Road) junction in Rodeo, New Mexico. [Photo on right by Kelsey Hanson, via OPAC.]

There is a $45 requested donation ($36 for Old Pueblo Archaeology Center and Pueblo Grande Museum Auxiliary members). Registrants have the option of visiting the Chiricahua Desert Museum on their own and at their own expense if they arrive early (the museum opens at 9) but they need to be ready to go on the tour promptly at 10:00 AM.

As with many Old Pueblo excursions, this is a tour that seems to be filling up quickly so you may want to act ASAP. You can visit Old Pueblo's page for this Cave Creek Canyon tour for registration information and further details. For other Old Pueblo tours and events to entice you, visit their Upcoming Activities page. Let's go!
