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: Sunday, April 6, through Tuesday, April 8, 2025: Lyman Lake State Park/Springerville/Casa Malpais AZ. Sunday-Monday, explore Lyman Lake's petroglyphs & archaeological site on your own or with a group. On Tuesday 4/8, we have guided tour of Casa Malpais archaeological site.

Online Via Zoom: Our March 16, 2022, Featured Speaker, Scott Nicolay

Scott_nicolay_March 16, 2022, 6:45PM via Zoom: This month's GCAS general meeting features archaeologist and PhD candidate Scott Nicolay. Specific topic TBD so watch this space for updates. (Teaser: a discussion of the ritual use of caves in the prehistoric Northwest Mexico/Southwest US region may be involved.)

Scott works with Dr. Holley Moyes out of the University of California at Merced in examining the ritual use of caves in prehistory. Scott's research interrogates the archaeological record of ceremonial caves from the prehistoric U.S. Southwest and Northwest Mexico in order to interpret major social, political and religious reorganizations that repeatedly swept the region prior to European contact, and how these shifts mesh both with prehistoric climactic change and contemporaneous events in the Mesoamerica core and periphery.

Earlier phases of his work suggest that some of the most important cave shrines in the Southwest served as the foci of ceremonial "catchment basins," accumulating offerings from large geographical areas, sometimes over periods of centuries, even millennia. Museums collections from these caves have received little attention since their original accession. Through a range of appropriate dating and sourcing techniques, Scott seeks to frame the provenience of these materials both spatially and chronologically against the larger backdrop of the region's prehistory.

Scott has worked on multiple archaeological projects both in caves and on the surface in New Mexico, Arizona, Utah, Colorado, Belize and Rapa Nui (Easter Island). He is also currently working with several other UC Merced graduate students on a project called Baskets 2 Bytes, conducting 3D digital photogrammetry of Indigenous California baskets in museum collections in order to make them available to weavers as digital objects. As always, please look for your email with your Zoom link to the GCAS meeting about a week before Scott's presentation. On the day of the meeting hop online about 6:45 PM to get settled and Scott will begin his presentation at 7PM sharp. Come join us!
