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."

GCAS Field Trip to Old Town and Fluorite Ridge

04_07_2019 Old Town CO IMG_5402Sunday, April 7, 2019, provided fine and sunny weather for a field trip. At least 14 members joined trip leader Greg Conlin on a two-pronged visit to the Old Town archaeological site and later, to the petroglyphs on the Bureau of Land Management's site at Fluorite Ridge. [Tip o' the hat to the GCAS's own Chris Overlock, for sharing the photos in this post!]

Old School Tattoo Tool

image from s.newsweek.comResearchers at Washington State University have (re)discovered the oldest tattooing tool in all of western North America. [Photo of tool on right, via Newsweek.] This 3-1/2 inch long, dual-needle tattooing instrument made out of two prickly pear cactus spines bound to a skunkbush sumac stem/handle with yucca fiber, had been excavated in 1972 from a midden at the Turkey Pen archaeological site in southeastern Utah. Based on the tool itself and human coprolites and maize cobs found in the same midden, the find was dated to 79-130 CE, about 2000 years ago during the Basketmaker II period. Similar tattooing tools retrieved from sites throughout the US Southwest were much more recent, having been dated to about 1100-1280CE. In other words, the Turkey Pen artifact now suggests that tattooing in our region had been practiced for at least 1000 years longer than previously believed.

Deferred, For All the Right Reasons

h/t to the GCAS's own Chris Overlock for hipping us to today's news in the Chicago Tribune.

The Art Institute of Chicago has indefinitely postponed the exhibition they had planned for May, 2019, of a private individual's collection of some 70 pieces of Mimbres pottery. The article indicates the Art Institute came to realize that grave goods comprise the majority of this private collection. Such items are inappropriate for public display.

“It’s not art,” said Patty Loew, director of Northwestern University’s Center for Native American and Indigenous Research, who...has followed the controversy within the community of Native American scholars. “If someone dug up your great-grandmother’s grave and pulled out a wedding ring or something that had been buried with her, would you feel comfortable having that item on display?”
