NEXT MEETING: Wednesday, May 15, 2024, 6:00 PM: our monthly meeting shifts to the Roundup Lodge in San Lorenzo (Mimbres Valley) for the summer months. Doors open at 6PM for a potluck dinner so bring your own plates, utensils, and a dish for yourself or to share with the group. Brief GCAS business meeting begins at 6:30 PM followed immediately by our evening's Featured Speaker, Preservation Anthropologist Aaron Wright PhD, who will present Indigenous Rock Imagery of the Sonoran Desert. Members and non-members alike are welcome to join us for an evening of good food and an engaging discussion. In order to offer our members a safe and comfortable experience at our in-person meetings the GCAS recommends each attendee take the masking, distancing, and vaccination precautions they feel are appropriate for themselves in group gatherings.

NEXT FIELD TRIP: Sunday, May 5, 2024: we aim for an unnamed Mimbres site on Fort Bayard/USFS land. Meet our trip leader, the GCAS's own Torie Grass, at the Big Tree parking lot (USFS directions are here), about a half hour's drive from Silver City. The group will start from the trailhead at 10AM sharp for a hike of about a mile one-way, north past the USFS Hot Shot buildings. The trail is mostly flat, with an incline up to a ridge at the end to reach the site. Torie advises to bring water and a lunch if desired, and to dress with appropriate pants for walking through some dry, stickery brush. Let's go!

Preservation Alert! Rock & Gem Magazine Publishes Tips for Collecting Artifacts

On November 3, 2023, one of our GCAS members alerted me to a disturbing article that has appeared at least twice in Rock & Gem magazine - most recently on October 30, 2023. The TL;dr is that the article encourages people to loot artifacts on public lands.

The GCAS was impelled to respond:

Earth Day 2023

Earth Day1 - good crowd in Gough Park Earth Day4 - interestThe GCAS operated their customary educational booth in Gough Park for Earth Day, April 22, 2023, thanks to members Marty Eberhart, Marilyn Markel, Kathryn McCarroll, and Marianne Smith. The typically breezy April day attracted 67 vendors to Gough Park - 15 more than had attended in 2022! The visiting crowds, estimated by a local newspaper at about 4000, included local residents, out of town visitors, and a healthy number of through-hikers on the Continental Divide Trail. The GCAS earned a prime spot in the park where our volunteers worked three separate tables with hands-on educational activities for all ages, as well as offering plenty of literature for the more intellectually inclined. Our booth displayed wrapped rocks as an eye-catcher and even sold a few to support our GCAS library and general fund. Many more passers-by grabbed our brochures so if you see new faces at future meetings, please make them all feel welcome!

Cultural and Ethical Implications in the Fossil Trade

Amber-field-cnnLoss of important scientific data does not just happen with cultural artifacts like Mimbres pottery. It happens with fossils, too. GCAS member Kathryn McCarroll links to an article discussing the international trade in blood amber, a fossil-rich amber mined only in Myanmar. Paleobiologist George Poinar recently wrote that "...scientifically valuable fossils...end up in carvings and jewelry and [are] lost for future generations...."

What Can Be Done with Disturbed Sites?

Campfire pit lined with 1000 y.o. wall stones Grafitti  modern Bulldozer tracks at pueblo site 1Archaeologist Lewis Borck, PhD, would answer: quite a lot.

"Disturbance" describes an archaeological site that has been altered by either natural forces (erosion, animal activity, etc.), previous archaeological excavations, or - as is often the case these days - by vandalism or looting as shown in the photos. Dr. Borck explained in an article he wrote for the Fall 2019 issue of American Archaeology (Vol. 23 No. 3 at p. 44) that his research as a preservation archaeologist focuses upon disturbed sites rather than sites that may be more intact. He says, in part,

Site Preservation 101

A gentle reminder, Dear Reader, ICYMI the first time:

Campfire pit lined with 1000 y.o. wall stonesPlease embiggen this photo by clicking on it. What you see is a recently-built, recently-used fire pit someone erected when they visited an archaeological site located on public land. They pulled stones out of a 1000-year-old pueblo wall to build up their fire ring nice and neat. Baffling, how often this happens around here and around the world, so following are some protips for campers visiting sensitive sites:

Space Archaeology: the Coming Thing

Globalexplorer J WolfeArchaeologists' use of satellite imagery, LIDAR, drones, and the like has taken an innovative turn thanks to Sarah Parcak PhD. In 2016 she and her organization launched an online platform, GlobalXplorer°, which uses crowdsourcing methods to analyze satellite images. Volunteers use the platform to help Dr. Parcak and her team identify possible archaeological sites and assess their risks of looting and destruction. DigitalGlobe (Maxar) provides the satellite imagery; National Geographic provides content and collaborative support.
