NEXT MEETING: Wednesday, April 19, 2023: the GCAS meets at 2045 Memory Lane in Silver City, New Mexico. Light refreshments provided; OK to bring your own light snacks or handy meal (burrito, etc.) & beverage if desired. Doors open at 5 PM for socializing. Meeting starts at 5:30 PM sharp with a short business meeting followed at 5:45 PM by featured speaker and GCAS member Carolyn O’Bagy Davis, who will discuss Bert and Hattie Cosgrove, avocational archaeologists who were instrumental in documenting and preserving a number of local sites including Arenas Valley's Treasure Hill. Meeting to adjourn about 7:00 PM. In order to offer our members a safe and comfortable experience the GCAS follows CDC and New Mexico Department of Health guidelines for indoor gatherings including masking, distancing, and vaccinations. We recommend all attendees follow the same.

NEXT FIELD TRIP: Sunday, April 2, 2023, beginning 9:00 AM: Regular GCAS field trip to City of Rocks State Park - view remnants of Apache shelters along the Cienega Trail, plus features in other easy-access locations like a rock shelter, Apache petroglyph, kiva, and multiple mortar holes. City of Rocks is about a 1-hour drive one-way from Silver City. At 9:00 AM meet at the Cienega Trail trailhead parking (a few hundred yards from the Highway 61 turnoff to the City of Rocks - look on the left side of the road for a parking area with a Port-o-Let). Walk the 1-mile easy Cienega Trail loop to inspect some off-trail features. About 11:00 AM, non-hikers can join the rest of the group to learn about the kiva site a few yards from the Visitor Center. About 11:15 AM, drive round the park’s perimeter road to the north side to view the rock shelter, Apache petroglyph, and mortar holes (short but moderately steep walk uphill from area near campsite #35). Picnic lunch follows at any convenient unoccupied campsite.

Still 3 Volunteer Opportunities!

Thatcher Rogers, 2018-2019 Coinman Grant Award Recipient

Rogers-photo-2017The GCAS is happy to have awarded funds through our group’s inaugural Nancy Coinman Grant Awards program for the 2018-2019 scholastic year to two graduate students of archaeology: Samantha (Sam) Bomkamp and Thatcher Rogers. They each have described the status of their research that our group’s Coinman awards helped support. Two days ago we published Samantha Bomkamp’s research summary; today we launch Thatcher Rogers’s progress report.

At the time of this writing Thatcher Rogers  is a PhD student in Anthropology/Archaeology at the University of New Mexico in Albuquerque. He is an experienced archaeologist of the southern New Mexico/northern Chihuahua region with expertise in ceramic analysis. He is also proficient at locating under-utilized museum collections and analyzing their data for potentially new insights.

The GCAS Coinman Grant Award funds helped Thatcher offset some of his transportation and related expenses in traveling from Albuquerque to a small museum in Ohio to investigate an extensive assemblage of artifacts from a 50-year-old avocational excavation at the Dutch Ruin (LA8706). The Dutch Ruin is a large, significant Cliff Phase (AD 1300-1450) pueblo in southwest New Mexico. The Ohio collection and associated documentation represent the only data that will likely ever become available to researchers given the extreme disturbances the Dutch Ruin site has suffered from decades of looting, erosion, and private land use.

Thatcher’s 2018-2019 project is part of his broader dissertation research that investigates the economic and societal relationships between the Casas Grandes (Paquimé) culture of northern Chihuahua and the Salado culture of southwestern New Mexico. Notably, the Dutch Ruin pueblo was also a quarry workshop and distributor of ricolite (a variety of serpentine), a trade commodity that circulated widely within southwestern New Mexico and into Casas Grandes territory. Thus Thatcher’s detailed analysis of the Dutch Ruin collection in Ohio may lead to more comprehensive interpretations of the regional relationships between the Paquimé and Salado cultures.

Congratulations are in order to Thatcher for his intensive archaeological research. We in the GCAS hope we hear from him periodically as his research and investigative reports continue into the future!
