Within the framework of a high mountain archaeological project, at the foot of the Iztaccíhuatl volcano, Iris del Rocío Hernández Bautista studies the rituals around a pre-Hispanic temple built in an artificial pond, which seems to represent a microcosm. The Nahualac Archaeological Project seeks to cover the greatest possible number of evidence and characteristics linked to the site, considering the relationships between the landscape and the archaeological context as the meaning of natural phenomena in ancient Mesoamerican thought.
