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!

BREAKING: New Evidence of Coronado Expedition's Route Through Arizona

Seymour and wall gunWe of the GCAS tip our hats to geologist/archaeologist Andrew R Gomolak! He kindly submitted to us an article and links to a series of short YouTube videos presenting Deni Seymour's findings from her archaeological excavations of the first sites in Arizona that can be attributed to the Coronado Expedition of 1539-1542. Andrew advises that the following materials are public information, with no restrictions on distribution; having enjoyed them ourselves we present them here for all our readers. Deni Seymour's work appears to be a monumental step forward in determining the Coronado Expedition's exact route through southern Arizona.

Andrew forwarded to us Deni's own description of her research:

MAREC Progress Report - Phase VIII

Bookcase construction WH2 Steve Collie builds bookcases WHRehab work continues in IFWEF's two upstairs rooms; the walls have been painted and the floors refinished, with final touches underway. Downstairs, the GCAS library's built-in bookshelves are in place and awaiting their final finish coats. (See volunteer Steve Collie at work in the first two photos over there on the left.)

Meanwhile, our GCAS volunteers spent an exciting morning assembling the furniture for the MAREC lab in the adjacent room. Our lab's two-station work bench sports a tabletop ledge shelf and an electrical power strip for small power tools. Two rolling trolleys stowed underneath this work station offer additional storage opportunities for all participants. A freestanding locking cabinet will keep researchers' work product secure. Our refinished hutch provides an extra work surface as well as space for educational materials.

MAREC Progress Report - Phase IV

Man glitterWe are excited to announce that our GCAS supporters have now contributed a total of over $7000 toward our project goal of $10,000. Such generosity has allowed us to continue through the typical fits and starts every rehabilitation project faces, and for that we thank all of our donors. We and IFWEF continue to coordinate the work of our two groups' volunteers with IFWEF's two professional contractors, while each group navigates the challenges of timing the purchase of construction materials subject to - shall we say - today's opportunity pricing.

The Day's Guest Blogger: Kyle Meredith

Our very own GCAS President, Kyle Meredith, tells us a tale of a trip to Peru from years past. He said he was prompted to write after having seen a blog post on our website with a link to an article that discussed Peru's papa nativas (native potatoes) and the archaeological site of Moray, Peru. Welcome back, Kyle!

Pisaq Peru - photo by K.MeredithA blast from the past! I have a propensity for falling in love with every place we go, but Peru more than others. So much of it looked so familiar. I had to look up Moray on the map because I could have sworn we had seen it, but actually it looked very similar to Pisaq in many ways, also in the Sacred Valley. In fact, the reason it looked so much like Pisaq is because one of their photos WAS Pisaq from almost the exact same spot that I took the photo.

Breaking: GCAS Submits Comment on the Gila River Diversion Proposal

GCAS_logo convertOn June 3, 2020, the GCAS Board of Trustees submitted a formal comment in opposition to the US Bureau of Reclamation's Draft Environmental Impact Statement (DEIS), which proposes a diversion of the Gila River in the general area of Virden, New Mexico. All of the Bureau of Reclamation's proposed alternatives for river diversion and construction appear certain to damage or destroy a large number of historic and archaeological sites throughout the proposed project area which spans both New Mexico and Arizona.
