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!

NEXT FIELD TRIP: TBA - watch this space and your newsletters for details as they develop.

Upcoming Events via Jornada Research Institute

Fill your calendar with a number of adventures on offer by the Jornada Research Institute. Consider any or all of the following:

Tuesday, April 15, 2025: sponsored by the Jornada Research Institute, Joan E. Price, MFA and JRI Research Associate, presents her most recent studies, MONEY RUNS UPHILL:THE PRIVATIZATION OF A COMMONWEALTH IN SOUTHERN NEW MEXICO. This presentation explores the cultural history of Tularosa, a Mexican American "acequia democracy" known for its equitable water irrigation and traditional settlement practices. It examines the ethnic conflicts and rapid cultural assimilation during the New Mexico Territorial Era (1848-1912), within the ambiguous relationship with the U.S. military presence and American capitalists who eventually gained control of the Rio Bonito, Rio Tularosa and the streams along the west slopes of the Sacramento Mountains. Contact Dave Greenwald for details.

Some Very Good GCAS News!

The GCAS is thrilled to announce that the Society for American Archaeology (SAA) has awarded their 2025 Robert S. Peabody Institute of Archaeology Award for Archaeology and Education to the GCAS. The Peabody is a $1000 monetary award dedicated to support organizations' programs that educate the public about the importance of preserving and protecting our archaeological resources. The GCAS, a 501c3 public charity, will receive the contribution in mid-2025 after the SAA annual meeting. Hearty thanks go to the Imogen F. Wilson Education Foundation (IFWEF) for their nomination, and to both IFWEF and WNMU Director Danni Romero for their letters of support.

We will certainly put these funds to good use to further the GCAS mission. Thank you, SAA, Dr. Romero, and the GCAS supporters within IFWEF!
