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's July Field Trip = 2022 Archaeology Fair Soon Coming!

Archswuofafair2022SBecause the first Sunday of July always collides with the July 4 holiday, the GCAS traditionally offers our "July" field trip at the end of June. So, let's all set aside time on Saturday, June 25, 2022, 10:00AM-12:00PM noon, to take our field trip to the 2022 Archaeology Fair hosted by Archaeology Southwest and the University of Arizona's Preservation Archaeology Field School at Gila River Farm in Cliff, New Mexico. The public is welcome and it's free of charge, so nothing could be better than joining GCAS members in learning about the project team's current discoveries through their informational exhibits, hands-on activities, and a brief site tour over easy terrain. General directions are: From the junction of Highways 180 and 211 in Cliff, drive 1 mile north, keep left (north) on Highway 293 and drive to Mile Marker 4. Just past MM 4, turn right into a driveway with a small sign that says, "Gila River Farm." Please use the parking area next to the large building down the driveway. Check their event flyer for more info: Download archaeology-fair-2022.pdf (455.6K). Learn more about the field school here, and here.

Safety measures will be in place so please be prepared to wear a mask and keep a safe distance. If you still have questions contact Archaeology Southwest. We'll see you at the Fair!
