Researchers from the National Institute of Anthropology and History (INAH), thanks to the discovery of a pre-Hispanic cemetery approximately 700 years old in the Archaeological Zone of Cerro de Trincheras, they maintain their theory about funeral practices of the ancient groups that inhabited northern Sonora, such as the cremation and burial of their deceased in pots.
The archaeologist Elisa Villalpando Canchola, who directs the research in the prehispanic site, declared that the location of this funerary context is very enriching and has been called "Hill of cremations”. Because the place shows great archaeological value they have decided to leave the "Hill of cremations”As an archaeological reserve.
The cemetery was investigated by zones of 10 × 10 meters through the elaboration of wells in strategic points. In this way, they have been able to verify that there is a funerary pattern that is repeated throughout the small hill. In the investigated section, 145 pots containing human remains belonging to 150 individuals and cremated animals were found, as well as two places dedicated to cremation and one place directly on the ground. In addition, three burials of children were excavated and found remains of quartz, earrings, bracelets and shell rings.
The pots come in a wide variety of shapes and forms: some are pumpkin-shaped, others oval with two perforations, and others with high necks. They also found clay pots. The entire collection belongs to what is known as the “Trenches Tradition" of the lower area of the Sonoran desert.
According to the investigations of archaeologists, the incineration process was carried out at high temperatures, leaving the remains ablaze until they were consumed. After, the remains were cleaned and deposited in the ceramic pots, which explains the lack of carbon and residues inside them.
Researchers James Watson and Jessica Cerezo Roman, from the University of Arizona School of Anthropology, collaborated with the analysis of the remains to determine its exact date. All the findings and investigations will be part of a museum script of what will be the permanent exhibition of the Cerro de Trincheras Visitor Center, the first archaeological zone open to the public in Sonora, which in 2012 received nearly 3,000 visitors, most from the north from Mexico and the southern United States.
Almost graduated in Advertising and Public Relations. I started to like history in 2nd year of high school thanks to a very good teacher who made us see that we have to know our past to know where the future takes us. Since then, I have not had the opportunity to investigate more in everything that our history offers us, but now I can take up that concern and share it with you.
