Students taking part in an extended study course in Mexico are soaking up information during guided tours through museums and ancient ruins while producing data of their own as they conduct field work for Colgate professor Anthony Aveni.

The 11 students have already visited Mexico City's National Museum of Anthropology and History and the ruins of Teotihuacán, Tenochtitlan, as well as other sites.

They also have started survey work near the ruins that is focusing on embedded stones that were placed in 16th century colonial churches.
