In the Sierra Mayor, located in the south of Mexicali, Baja California, they have been discovered eight archaeological sites dating between ago 400 and 7000 years and that are linked to the Cucapá culture.
The authors of this discovery have been specialists belonging to the National Institute of Anthropology and History (INAH) who have found a multitude of animal bones (some of them already extinct), ceramics and other objects, as well as places where iron oxide was used as a pigment for the body and mural paint.
The first of them was found by the archaeologist Antonio Porcayo Michelini, responsible for the project under the name of «Registration and Rescue of Archaeological Sites in Baja California - Phase: Mexicali Municipality«. He himself was the one who in 2008 began working in Sierra Mayor to incorporate new research on the place into the INAH registry.
Sierra Mayor It is a region with an arid climate that reaches temperatures of up to 50 degrees Celsius, in this place the clay layer of the hills is exposed and the naked eye can see the iron oxide deposits and important geological moments that have taken place throughout of the formation of the peninsula.
There is evidence that there were other nomadic groups apart from the Cucapá. The zones are made up of rocky structures known as "playpens”That were used as bases. Each camp has about seven or eight corralitos, which indicates that there were several families that lived temporarily. Two of the corralitos had hundreds of remains of animal bones that were used as food since some of them have traces of dismantling, others, however, were used as tools.
The archaeologists initially thought that they were only areas where they spent the night, but now there is evidence that they were also places where ovens were located to cook and that later they were covered with earth in order to use the heat of the ground to warm their bodies during the winter.
Another aspect to note about the place is that they have been found fresh and saltwater fish remains which confirms the fact that the Cucapá were dedicated to fishing. Among the fish remains is the humpbacked matalot (Xyrauchen texanus), a species that became extinct in the early 19th century, similar to trout and that only survives in small populations near the Grand Canyon.
I was born in Madrid on August 27, 1988 and since then I started a work of which there is no example. Fascinated by both numbers and letters and a lover of the unknown, that is why I am a future graduate in Economics and Journalism, interested in understanding life and the forces that have shaped it. Everything is easier, more useful and more exciting if, with a look at our past, we can improve our future and for that… History.
