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!

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!

Next GCAS Meeting Features Speaker Lee Brown on Prehistoric Mining

The GCAS's next in-person meeting will be Wednesday, February 19, 2025, 6:00 PM at 2045 Memory Lane in Silver City, New Mexico. On this occasion we feature the GCAS's own Lee Brown, retired mining engineer, who will discuss evidence of Prehistoric Mining in North America with highlights from our own region. Doors open at 6:00 PM with light refreshments provided with a brief socialization period and business meeting, to be immediately followed by Lee's presentation.

GCAS member (and former GCAS treasurer) Lee Brown - formerly known as Gary Brown - was born and raised in New Mexico and has lived in towns as far-flung as Aztec, Mountainair, Socorro, Gallup, Rio Rancho, and now Silver City. He earned his B.S. in Mining Engineering from New Mexico School of Mines in Socorro and completed a 40 year career in the Mining and Steel Industry, mostly in the field of extractive metallurgy under "all sorts of funky engineer titles," as Lee puts it. He worked from bottom to top: laborer, operator, supervisor, underground miner, and operations superintendent. He retired as Chief Engineer for the Concentrator at the Chino Mine right here in Grant County. Lee has continued his lifelong interest in mineral collecting and mining history, enjoying collecting adventures in New Mexico, Arizona, Colorado, Utah, Nevada, Michigan, Montana, Alaska, Wyoming, South Dakota and Georgia, in addition to his archaeological adventures throughout the southwest US, Peru, Yucatan, and Spain.

See you there!
