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!

Our Next Monthly Meeting Features Carolyn O'Bagy Davis

Carolyn O. Davis Cosgrove Camp at Swarts  1927Wednesday, April 19, 2023: the GCAS meets at 2045 Memory Lane in Silver City, New Mexico. Light refreshments provided; OK to bring your own light snacks or handy meal (burrito, etc.) and beverage if desired. Doors open at 5:00 PM for socializing. Meeting starts at 5:30PM sharp with a super-short business meeting followed at 5:45PM by this month's Featured Speaker: historian, award-winning author, and GCAS member Carolyn O’Bagy Davis. Carolyn is a fourth-generation descendant of Utah pioneers who has written 16 books on the history of archaeology, quilting, and Southwestern history. So far. When taking breaks from writing, she has curated numerous traveling museum exhibits. Please join us as Carolyn reintroduces our group to Bert and Hattie Cosgrove, avocational archaeologists who were very active in our area during the 20th Century and who were instrumental in documenting and preserving a number of local sites, including Treasure Hill in the Arenas Valley. As Carolyn describes in Hattie Cosgrove: Pioneer Mimbres Archaeologist:

Hattie-cosgroveUpon her first visit to the Gila Cliff Dwellings in 1907, Hattie Cosgrove was captivated by the amazing traces of a vanished culture. With her husband, she began digging in local sites, but soon realized that random digging was destroying sites and the valuable information they contain. Hattie and Burt visited professional archaeological excavations and studied to learn scientific archaeological practices. In 1923, the couple was hired to excavate Mimbres sites for the Peabody Museum at Harvard, going on to later work at Stallings Island, Pendleton, and Awatovi. Hattie Cosgrove, considered the first female to work professionally as an archaeologist, followed her vocation to the end of her life. She wrote, “My heart is in the work.”

Expect our April 19 meeting to adjourn about 7:00PM. In order to offer our members a safe and comfortable experience the GCAS follows CDC and New Mexico Department of Health guidelines for indoor gatherings including masking, distancing, and vaccinations. We recommend all attendees follow the same.
