NEXT MEETING: Wednesday, August 17, 2022, 7PM, online via Zoom: 7:00 PM: The GCAS welcomes West-Mexican archaeologist Manuel Dueñas Garcia as our Featured Speaker. As usual for our Zoom meetings we invite everyone to hop online about 6:45 PM to get settled while we have a brief-to-nonexistent business meeting. Manuel will begin his presentation at 7PM sharp to share his perspectives on Aguascalientes Archaeology and the Northern border of Mesoamerica during the Epiclassic (600-900 CE). Members, check your email about a week prior to the meeting to receive your Zoom link. We'll see you online as Manuel discusses new insights about our region.

NEXT FIELD TRIP: TBA but meanwhile, remember that to protect vulnerable resources we offer our field trips to members only. Members’ invited guests are welcome, as long as they ride in that member’s vehicle.

As always, please look for your email with your Zoom link to the GCAS meeting about a week before Ron's presentation; Plumed serpent glyphon the day of the meeting hop online about 6:45 PM to get settled - Ron will begin his presentation at 7PM sharp. Come join us to hear him describe,

"The Stone Calendar Project has been studying rock art sites throughout the Southwest and northern Mexico identifying glyphs that record specific times of the year using unique sun light and shadow interactions. We encounter a wide range of glyph images at all of the sites, helping us to identify the cultural origin of the rock art. The plumed and/or horned serpent is found at many sites, up and down the Rio Grande corridor, down into Mexico, and in the Four Corners region. In some locations the crested serpents appear to have horns, while in others they have both horns and plumes, and in some cases the crest is unclear. The plumed serpent appearance in the southwest has largely been attributed to infusion of the Mesoamerican plumed serpent such as Quetzalcoatl, from the highlands of Mexico. Horned serpents appear early in the Southwest and may have fused together with the plumed serpent to form the horned and plumed serpents seen at discrete locations in the southwest. This presentation will summarize the crested serpent rock art locations and regional styles, and compare them to other mural and ceramic images. Religious practices in the Pueblo World still include the crested serpents, and ethnographic records also provide contemporary images for comparisons to prehistoric rock art images."

Ron Barber was born and raised in the oil fields of South America, out in the middle of the boondocks. His parents hauled their kids through the mountains, deserts and jungles; always in search of new adventures. Encountering indigenous cultures and ancient sites led to Ron's long-term interest and curiosity about lost civilizations. He is an explorer by nature, an engineer by profession.

Ron is a Mechanical Engineer with over 40 years at the national laboratories; Lawrence Livermore in California and Los Alamos in New Mexico. Over the last 10 years he has focused an effort to study rock art throughout the southwest, specifically looking for glyphs that might provide insights into early astronomical knowledge. He has applied his engineering background to develop a systematic approach to surveying and identifying glyphs for potential study as well as developing 3 dimensional modeling of light and sun interactions.
