Important Research at Mount Tlaloc in the State of Mexico

January 15, 2023

Researchers have discovered that a straight stone causeway on Mount Tlaloc, an extinct volcano, aligns with the rising sun on February 23/24. Mount Tlaloc is in the State of Mexico, where a shrine complex was built by the Mexica people. It was associated by the Aztecs with the rain god Tlaloc. And was seen as the heavenly home of Tlaloc, Tlalocan. Great rituals, offerings and human sacrifices were offered to Tlaloc at the beginning of the rainy season.

If an observer stands in the lower part of the causeway looking upwards on February 23/24, they will see the sun riding exactly in the middle of the path. The Aztec date of the New Year is February 23. They used this date to keep their agricultural calendar in line with the solar year.  

The research is published in the Proceedings of the National Academies of Sciences (PNAS)
