Archaeologists just assumed that women made the pottery at Chaco Canyon in New Mexico 1,000 years ago. Then they started thinking like cops—and things got interesting.
A question from student with a law-enforcement background has sparked a new analysis of pottery from one of America’s most important ancient centers—and the results are turning archaeologists’ assumptions about “women’s work” on their head.
The Chaco Canyon communities of northwestern New Mexico were a center of significant cultural and religious activity from 800 to 1200 A.D. The Ancestral Puebloan people who lived in the region produced a type of pottery called “corrugated ware,” made by coiling thick ropes of clay on top of one another to form large vessels.
The general assumption has been that women in the Chaco region were responsible for making corrugated ware 1,000 years ago—an assumption based primarily on much more modern observation.
“Pueblo women today have historically made pottery and taught their daughters, so the thinking is that maybe that’s a reasonable inference we can project back in time,” says John Kantner, of the University of North Florida and lead author on a new study on corrugated ware published today in the Proceedings of the National Academy of Sciences. “But that doesn’t sit well with many archaeologists since we can’t directly observe who was making the pottery.”
Since each layer of corrugated ware was secured by pinching it between thumb and fingertip, it preserved the fingerprints of the potters who made them. Could a study of those fingerprints reveal the gender of those potters?
The study revealed that 47 percent of fragments had prints with an average ridge breadth of 0.021 inches, corresponding to male fingerprints; while 40 percent had an average ridge breadth of 0.016 inches, corresponding to female or juvenile prints. The remaining 12 percent had overlapping averages and were categorized as “unknown sex.”
This study is the first to produce direct evidence of gender divisions in ceramics production in the Chaco Canyon area.
“This certainly challenges the notion that one gender was involved in pottery and one was clearly not,” Kantner says. “Perhaps we can begin to wonder if that’s also true for other activities that took place in this community at this time, and challenge the idea that gender is one of the first things to become divided in the labor of a community.”
Barbara Mills, a ceramics expert and archaeologist at the University of Arizona, says that this study’s findings are significant in that they support what is observed in economies with increased specialization due to growth: men’s involvement in activities where they formerly hadn’t participated.
“In cross cultural studies, when men become involved with potting, it means they’re spending more of their time on that versus other activities,” Mills says. “But that also tends to occur when there is a benefit. Men take over—it’s very well documented. The whole family gets involved. This study presents good evidence for increasing specialization.”
“The archaeological record shows huge volumes of stuff going into Chaco,” Kantner says. “Whether it’s tribute that’s expected from outlying villages, or pilgrimages, it may have been a situation where people wanted to be more involved in producing the pottery that went to Chaco.”
Carrie Heitman, a Chaco Canyon anthropologist at the University of Nebraska-Lincoln, says she’s intrigued by the results, but that more comparative studies from other Chacoan sites with corrugated wares are necessary to bear out Kantner’s findings.
