Archaeologists Find a Secret Tunnel Hidden Beneath Mexico's Pyramid of The Moon
This way to the underworld.
DAVID NIELD 8 JUL 2017
It's amazing what the best computer scanning technology can do these days like revealing a hidden passageway beneath the Pyramid of the Moon near the ancient city of Teotihuacan in Mexico.
The straight tunnel sits about 10 metres (33 feet) underground and is thought to represent a pathway to the underworld, giving us new insight into the culture and rituals of the Teotihuacan people.
Archaeologists from the National Institute of Anthropology and History (NIAH) in Mexico used an imaging technique called electrical resistivity tomography to find the secret tunnel, which can map underground structures (and the gaps inside them) based on how they resist an electrical current.
"The discovery would confirm that the inhabitants of Teotihuacan followed the same pattern in their large-scale temples, and that their function would be to emulate the underworld," one of the archaeologists, Veronica Ortega, told the Associated Press.
