Everyone is welcome to join us online at 7:00 PM on Wednesday, April 20, 2022, via Zoom when our Featured Speaker, Ron Barber, creator of the Stone Calendar Project, presents Chasing the Plumed Serpents of the Southwest. As always, please look for your email with your Zoom link to the GCAS meeting about a week before Ron's presentation; on 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,

Ron Barber, creator of the Stone Calendar Project, has been studying rock art sites throughout the Southwest and Northern Mexico identifying glyphs that mark specific times of the year using unique light and shadow interactions.  He has some survey predictions for glyphs along the Gila Narrows and other southern sites and is looking for volunteers to help in further research.

Anyone who is interested in spending time in the field recording/filming calendar sun light interactions in the region, please contact Ron directly at barbers6@aol.com . Here's more of Ron's background:

If you're curious about archaeological sites and research along the Gila River, there are two upcoming online lectures sure to suit you. Get your calendar ready for:

Until you can schedule a trip to the Santa Fe/Espanola area to see the Mesa Prieta petroglyphs for yourself, please enjoy a virtual tour courtesy of the Archaeological Conservancy's Virtual Tour Series. To date the Archaeological Conservancy has released four episodes showcasing some of the sites they have acquired for preservation and protection. They are all worth your time.

Scroll down at this link to check out Episodes 1 through 3, but Episode 4 is the one that is all about petroglyphs the like you have never seen before. It features their Wells Petroglyph Preserve narrated by their archaeologist, Chester Liwosz, and former owner/donor/founder of the Mesa Prieta Petroglyph Project, Katherine Wells. If time permits you can watch the full hour-long virtual tour here, or see the same episode in four shorter segments by clicking here.

Of course, the Archaeological Conservancy also has an ongoing Virtual Lecture Series to keep you apprised of the latest in research. Get busy!

The Mesa Prieta Petroglyph Project in Velarde, New Mexico, recently added to their website two short virtual tours of some select petroglyphs under their protection. If you cannot travel to tour Mesa Prieta in person, these virtual tours give you a taste of how unique the site with its 100,000+ petroglyphs truly is. Descriptive text accompanies these virtual images, which can be rotated in 3D for enhanced viewing pleasure. Check out their Heraldic Lions Tour or their Shields and Shield Bearers Tour, then follow the link to their Sketchfab page to have fun with even more 3D petroglyph images!

Some avocational archaeologists have already learned of the fascinating technology of D-Stretch, aka decorrelation stretch, a digital imaging tool that was originally developed to enhance (i.e., "stretch") the color differences in aerial photographs. Today, this technology has become more widely used and user-friendly to boot. It is now an essential tool to analyze rock art images, especially ones too faint for the naked eye to see.

Join us Wednesday, February 17, 2021, at 7:00 PM on Zoom to hear our Featured Speaker, Lawrence (Larry) Loendorf of Sacred Sites Research, Inc. explain the relationships he and other anthropologists, archaeologists, and ethnobotanists have studied between "Medicinal Plants and Rock Art Sites in Southern New Mexico."

Larry was born and raised in Montana. His BA and MA degrees are in anthropology and archaeology from the University of Montana and his PhD is from the University of Missouri-Columbia. After receiving his PhD, he taught at the University of North Dakota for 22 years and then moved to undertake research and teaching at the University of Arizona and New Mexico State University. He currently manages Sacred Sites Research, Inc., a non-profit company that is dedicated to protecting ancient pictograph and petroglyph sites.

Wednesday, November 18, 2020, 7:00 PM: GCAS general meeting via Zoom. No business meeting, which means we will begin by welcoming our Featured Speaker, archaeologist Margaret Berrier, who will share with our group "Pisciform Iconography of the Jornada Mogollon," also known as, "Let's Look at Fish: Pisciforms in the Jornada Mogollon Region of Southern New Mexico, Northern Mexico, and West Texas." Margaret points out,

"Numerous examples of fish are depicted on ceramics of the Southwest's ancient Mimbres Culture. These are well illustrated in publications and the Mimbres Pottery Image Digital Database (MimPIDD). However, no significant catalog or publication exists for the Southwest's Jornada Mogollon culture that was partly contemporaneous with the Mimbres. This presentation will include examples of pisciform iconography (fish forms) and their distribution in the Jornada Mogollon area. It also summarizes ethnographic accounts of fish use and interpretation of fish iconography. Included in the presentation will be many examples and comparisons with other archaeological artifacts."

The Mesa Prieta Petroglyph Project in Velarde, New Mexico, has produced a virtual tour of their extensive site that anyone can enjoy. You may have to navigate through one or two screens on this link, or perhaps this link, but it is worth a few minutes of your time to see glimpses of this very unique and important site. If you have never visited the site you will enjoy this brief introduction to it. If you have already visited in person you will be thrilled to see some of its highlights again.

Please also consider sending a donation to the MPPP to support their preservation efforts. Once it becomes feasible for public health you may consider visiting the site yourself. Plan a few days, as there are 6 different trails among the petroglyphs to sign up with a docent to see!
