Copilco and the Preclassic Tunnels

Copilco and the Preclassic Tunnels

The four tunnels of the Copilco quarry they have been explored again by archaeologists from the National Institute of Anthropology and History. These tunnels were dug about a century ago by Manuel Gamio, a famous Mexican anthropologist who has disappeared, and in these were found remains of a possible pre-Hispanic settlement of the Pre-Classic or Middle Formative.

In the latest exploration, what appears to be the foundation of a house and an area used for storage or perhaps funeral use have been discovered, which has made Copilco is positioned as one of the most representative places of the middle school in Mexico.

José Ignacio Sánchez Alaniz and Emma Marmolejo Morales, archaeologists in charge of the project, have stated that this is a very important place from which valuable information will surely be drawn to fill in the puzzle of the history of the country for many centuries.

Both agreed that Manuel Gamio was very interested in knowing the chronology of the Valley of Mexico and he was aware that the quarries of Pedregal de San Ángel and Coyoacán had found different elements that reveal a pre-Hispanic occupation, so in about 1917 he asked for a permit to excavate. This is how Gamio was able to discover the four tunnels, which have different extensions, heights and widths.

There were not exactly few objects that were found as burials of both children and adults in cylindrical pits, various house foundations, ceramics, obsidian points, sculpture, knife-like tools and many other utensils made of different materials.

In later years excavations were carried out in the other three tunnels where, thanks to the findings, confirmed the existence that someone lived there in the archaic or pre-classic era, but everything was buried under the Xitle del Ajusco volcano lava there between 630 and 627 BC, something that archaeologists continue to investigate even today.

Up to now, different cleaning stages They were able to establish two excavation fronts in various tunnels, the ones considered most interesting archaeologically speaking. Two layers of ash were found in them, one between four and five centimeters thick and another between 20 and 30 centimeters, prior to the eruption of the volcano.

Further down a black layer was found where a greater concentration of human activity was found, something that reveals that the inhabitants in this area were closely linked to volcanic eruptions although they never left this site until the great eruption. Now it's time to work more in this place and get more data that reveals part of that history of Mexico.

After studying History at the University and after many previous tests, Red Historia was born, a project that emerged as a means of dissemination where you can find the most important news of archeology, history and humanities, as well as articles of interest, curiosities and much more. In short, a meeting point for everyone where they can share information and continue learning.
