The ancient urban center of Teotihuacan covered about 20 square kilometers.
About the ASU Teotihuacan Laboratory
It was initiated by professor René Millon, of the University of Rochester, who directed the detailed mapping of the entire city in the 1960s, combining air photos and mapping with surface reconnaissance of over 5,000 individual tracts, making notes on visible features and collecting nearly a million pottery fragments and other ancient objects from the surfaces of these tracts. His Mapping Project remains unique for its combination of scale and detail. It is an indispensable basis for planning further work at the city.
ASU research professor George Cowgill took over as director of the present laboratory location in 1986 with assistance from the National Science Foundation, following Millon’s retirement. Today it houses the materials collected by a number of projects besides Millon’s Mapping Project, and provides housing and work space for up to 10 researchers, including students, with a total floor space of about 1,160 square meters.
Professor Michael E. Smith, a renowned Mesoamerican expert and archaeologist, took over directing the lab in 2015.
