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!

Navajo Culture On Mars!

Mars-Rover-600x-SM-1Earlier this month NASA reported some very uplifting news about their Perseverance Rover Team's research on Mars. Via Forbes, because "...a big contingent of Perseverance science is centered in universities and national labs in New Mexico and Arizona, which include traditional Navajo land...", the team is naming a number of Martian geological features with words from the Navajo language.

The article continues:

"Before launch, Perseverance’s team divided the Jezero Crater landing site into a grid of quadrangles...The team decided to name these quads after national parks and preserves on Earth with similar geology. Perseverance touched down in the quad named for Arizona’s Canyon de Chelly National Monument...

Aaron yazzie nasa...Mission scientists worked with a Navajo (or Diné) engineer on the team, Aaron Yazzie of NASA’s Jet Propulsion Laboratory in Southern California, to seek the Navajo Nation’s permission and collaboration in naming new features on Mars.

Navajo Nation President Jonathan Nez, Vice President Myron Lizer, and their advisors made a list of words in the Navajo language available to the rover’s team. Some terms were inspired by the terrain imaged by Perseverance at its landing site. For example, one suggestion was “tséwózí bee hazhmeezh,” or “rolling rows of pebbles, like waves.” Yazzie added suggestions like “strength” (“bidziil”) and “respect” (“hoł nilį́”) to the list. Perseverance itself was translated to “Ha’ahóni.”

Mr. Yazzie and the Navajo Nation view this as a significant opportunity to inspire Navajo youth not only to learn the value of their native language, but to appreciate Navajo contributions to science and engineering as well as to seek out careers in those fields.

Today, the traditional homeland of Dinétah has reached out and spoken to another planet. Those of us who are the Navajos' Southwestern neighbors send them our very best congratulations for enriching the cultural history - and the future - of us all.
