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 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!

GCAS August 2024 Field Trip To Treasure Hill

IMG_20240804_103935204_HDRcopy IMG_20240804_101346351_HDROn a very warm and sunny Sunday, August 4, 2024, twenty one members of the Grant County Archaeological Society (GCAS), coming from as far away as El Paso, Texas, gathered together to explore the Archaeological Conservancy’s Treasure Hill site located in our very own Arenas Valley. Archaeologists consider this Late Pithouse-to-Mimbres Classic site (roughly 550 CE – 1130 CE), comprising a total of 100 rooms in 6 room blocks plus an additional 24 outlying sites, to have been the largest Mimbres community in the middle Rio de Arenas/Whiskey Creek watershed. Unfortunately Treasure Hill, like so many other Mimbres sites, has suffered heavy looting from the late 19th Century to the present. A major road and residential development surround it and it has accumulated windblown trash as well as garbage carried in by unauthorized visitors.Consequently...

Next GCAS Meeting Welcomes Dylan Person as Featured Speaker

DylanPerson crop2Wednesday, August 21, 2024, 6:00PM Mountain Daylight Time (New Mexico) online via Zoom: the GCAS August meeting features speaker Dylan Person, PhD, who will present How Stone Tool Reduction Styles Varied (or didn't vary) Between Social Units/Family Groups at the Harris, La Gila Encantada, and Elk Ridge sites. Join us on Zoom starting at roughly 5:45 to get situated and socialize before we begin at 6:00 PM sharp with a very brief business meeting after which we bridge to Dylan's presentation. A Q&A session will follow his talk. Check your email inbox for your Zoom invitation about one week before the presentation.

Dr. Dylan Person is an archaeologist who works and does research in the American Southwest and the Great Basin. He received his PhD in 2023 from the University of Nevada, Las Vegas working Dr. Barbara Roth on sites from the Mimbres culture of southwestern New Mexico. His research focused on lithic technology, types of tool-stone used, and how these things related to group interactions and social units at the Harris, La Gila Encantada, and Elk Ridge sites.

Person’s research has investigated lithic debitage, a class of lithic artifacts that were either simple stone flakes used for cutting tasks, blanks for more complex lithic tools, or just stone shatter resulting from lithic reduction. His talk to the GCAS will describe how he has used rock identification and the size and shape of debitage flakes to determine technologically-based styles present in the three Mimbres sites described above. He will also discuss how these relate to social groups both at the individual sites as well as in the greater Mimbres area overall.

Please hop onto Zoom with us to recognize how seemingly random bits of rocks help create a more significant picture of the archaeological record as a whole.

Upcoming Free Lecture at WNMU Museum

WNMUMuseumWednesday, June 26, 2024, at 6:30 PM in the WNMU Museum - FREE and open to the public: Dr. Jeffrey Ferguson, University of Missouri Assistant Professor of Anthropology/Research Associate Professor, presents: The Next Stage of Archaeometry in Southwestern Archaeology: New Ways to Explore Old Data. Dr. Ferguson explains, "the application of analytical chemistry and other scientific techniques to Southwestern Archaeology can reveal detailed information about ancient behavior from trade and exchange to large-scale social interaction. I will present three main analytical techniques employed at the Archaeometry Laboratory at the University of Missouri Research Reactor Center (MURR) with a focus on what we can learn about people in the past. These techniques have been in use for decades and we are looking at ways to synthesize the accumulated data at much larger scales. I will also present some new research on site identification using drone-based LiDAR in west-central New Mexico." Join Dr. Ferguson in the WNMU Museum's air-conditioned splendor for an informative discussion surrounded by Mimbres artifacts. Although this lecture is free, please consider making a cash donation in any amount to the WNMU Museum at the door to support their ongoing curation efforts.
