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!

GCAS Field Trip to Paquimé, Part III

1 - Mata Ortiz detail work Potter fine detailTo read the complete narrative of the GCAS field trip of May 2-4, 2018, see Part I here, and Part II here.

Day 2: May 3, 2018. Shopping day in the artisans' town of Mata Ortiz. Because the Grant County Archaeological Society embraces art and culture in all its forms. (h/t Marcia Corl for close-up photo of fine ceramics detailing.)

Juan Mata Ortiz is a town of about 1200 people located several miles south- 5 - LtoR  Kevin  Meem and Lee examine potssouthwest of Nuevo Casas Grandes, Chihuahua, Mexico. It was established in the late 19th Century  as "Pearson," but after the 1916 Mexican Revolution it renamed itself "Juan Mata Ortiz" in memory of an army colonel and local hero who had fought against the Apache. The town's economy had been based exclusively on agriculture, but beginning in the late 1970s/early 1980s a ceramics tradition began to develop that now provides the town and its inhabitants with a more stable and diverse economy than agriculture alone had afforded.

Generally speaking, the shapes of Mata Ortiz ceramics and their motifs are a revival of, and a modern 23 - Museum  olla detail of turquoise paint  Mound of the Offerings22 - Museum  olla  Mound of the Offeringsinterpretation of, the prehispanic ceramics of the Paquimé culture. Many families in this small town include highly skilled ceramicists among their members. A Google of the phrase "Mata Ortiz ceramics" produces good examples of current Mata Ortiz ceramic art. These two photos of thousand-year-old ollas recovered from the ruins of Paquimé and which are now in the site's museum, illustrate the Paquimé style of ceramics on which modern Mata Ortiz pottery is based.
