During the 2017 field season, the Plaza of the Columns Project used a special type of investigative tool called LiDAR (Light Detection and Ranging) to verify archaeological features out in the field. This method of remote sensing integrates GPS technologies, Inertial Measurement Unit, and lasers in order to collect altitudinal data. The combination of these sources help to define the surface of the terrain by generating digital elevation models (DEM) for us to further interpret and analyze.
In general terms, this technique allows us to recover traces of the past, either pre-Hispanic, colonial, or historical, which today are reflected in cultivated terraces, mounds or artificial elevations, and jagueyes or water reservoirs.
These features are blurred in what are now nopaleras (terrain covered in the nopal or cactus plant), agricultural fields, or even modern day villages. But thanks to this surveying method, one can outline the dimensions and proportions of architectural or hydraulic features of the past.
Coexistence with the settlers
While surveying the area, we have had the pleasure to interview landowners and gather historical information of past populations. They recalled early childhood stories told by their parents or grandparents about the foundation or organization of their communities since the beginning of the 20th century.
In addition to sharing their experiences, they provided information on the elements that we recognize today in LiDAR images. For example, in the town of Ixtlahuaca in the municipality of San Martin of the Pyramids, interviewees Juan Guillermo Castro, Pablo Rivero, Alejandro Hernández Ramirez, and Sebastián Medina shared stories when the only accessible water was from the water reservoir located in the center of the village. They also recalled the time when this part of the valley belonged to the Hacienda of Cerro Gordo. Other interviewees, Genoveva Diaz Alba with her daughters Lidia and Maria del Carmen Delgadillo Diaz, told us that her husband decided to modify the terrain in the 1970s in order to better cultivate it.
In addition to plentiful stories, some locals were highly generous and went over and beyond. Mr. Filemon Macías Juárez of San Lorenzo Tlamimilolpa not only granted us permission to visit his land but also donated a collection of ceramic materials that he collected throughout his lifetime. This allowed us to increase our comparative sample with late materials and correspond them to the Postclassic occupation of the region.
The enthusiasm and cooperation of the landowners are a result of the clear and transparent management of our objectives. Often times, the locals are contacted by other institutions with much less cordial terms. Therefore, we feel committed to establish clear communication and respect. We want them to feel informed and involved, whether by asking them to personally see the work we do, responding and explaining any personal doubts or observations, or adjusting to their needs and availability.
It is important to highlight the support provided by the municipal and auxiliary authorities of Ixtlahuaca and Santa Maria Palapa in the municipality of San Martin of the Pyramids. We also thank San Juan Teotihuacan in the Barrio de Purificación, San Sebastián Xolalpan, San Francisco Mazapa, Santa Maria Coatlan, and San Lorenzo Tlamimilolpan. Lastly, we gives thanks to private organizations such as the Animal Kingdom Zoo.
In the first excavation season (2015), four sectors were selected to be excavated and were each given a front name: Front A, Front B, Front C, and Front D. For the second season (2016), we opened a new sector called Front E.
Directing each front is an archaeologist responsible for overseeing operations and managing a team of field assistants as well as one or more additional archaeologists.
Verónica Ortega Cabrera
Director of Front A (2015-2017)
Dr. Ortega is the Assistant Director of the Archaeological Zone of Teotihuacan for the National Institute of Anthropology and History (INAH). She knew she wanted to be an archaeologist from her first memorable experience at the age of six when she saw the famous Mexica-Aztec Coyolxauhlqui sculpture.
She studied archaeology at the National School of Anthropology and History (ENAH), followed by a master’s degree in Mesoamerican Studies at the National Autonomous University of Mexico (UNAM) and a doctorate at the Faculty of Philosophy and Letters at UNAM. She also has a degree in Communication Science at UNAM.
Dr. Ortega has worked directly with excavations at the Oaxaca Barrio at Teotihuacan for her doctoral project. She specializes in the archaeology of the Central Highlands in Mexico, particularly in Teotihuacan. Dr. Ortega is also the director of a few projects focused on the conservation and research of various sites including the excavations at the Moon Pyramid Plaza and the Quetzalpapálotl Palace. In her current position, she is in charge of various aspects of the site, such as supervising research and conservation projects and designing and implementing outreach programs.
Director of Front B (2015-2017)
Dr. S. Sugiyama is a professor at the Graduate School of International Cultural Studies at Aichi Prefectural University, Japan, and is a research professor for the School of Human Evolution and Social Change at Arizona State University, U.S.A., where he obtained his Ph.D. in 1995.
His major research interests include Mesoamerican archaeology, ancient complex societies, urbanism, architecture, symbolism, and theories of cognitive archaeology. He has participated in numerous archaeological projects in Japan, Guatemala, and Mexico. He has been very involved in the ancient urban city of Teotihuacan where he has carried out intensive excavations at the Moon Pyramid, the Feathered Serpent Pyramid, and the Sun Pyramid.
Dr. S. Sugiyama has received several awards, including Commendations from the Ministry of Foreign Affairs in Japan in 2012 and the Shanghai Archaeology Forum Award in 2013. He has published more than 80 chapters, various articles in academic journals, and books (e.g., Human Sacrifice, Militarism, and Rulership: Materialization of State Ideology at the Feathered Serpent Pyramid, Teotihuacan, Cambridge University Press, 2005).
Director of Front C (2015-2017) and Front D (2015-2017)
Dr. N. Sugiyama joined the Sociology and Anthropology Department at George Mason University (GMU), Virginia, U.S.A., as an assistant professor in spring 2016. She received her Ph.D. in Anthropology from Harvard University in 2014 where she transitioned to become a Peter Buck postdoctoral fellow at the National Museum of Natural History at the Smithsonian Institution.
For her dissertation, she documented the earliest evidence of carnivore management in Mesoamerica at the site of Teotihuacan where pumas, jaguars, wolves, golden eagles, and rattlesnakes were sacrificed. She did her postdoctoral work on the felids associated with Altar Q in Copan, Honduras, and demonstrated a wider practice of managing wild carnivores for ritualistic purposes. In both cases, she combined zooarchaeological and isotopic data to reconstruct how past human-animal encounters were integral components of the cosmological and socio-political landscape. She is currently working towards building an Archaeological Sciences lab at GMU to continue her interest in utilizing isotopic analysis to reconstruct ancient animal and human diets, migration patterns, and environments.
She has conducted her fieldwork, lab work, and writing with support from various institutions including the National Science Foundation, the Smithsonian Institution, Dumbarton Oaks Research Library and Collection, Harvard University, and the Fulbright Foundation.

Ariel Texis Muñoz(2015-2016, 2018-2019)
Ariel is a graduate archaeologist of the Universidad de las Américas Puebla (UDLAP) and was a thesis student of the Tlalancaleca Archaeological Project, Puebla. As a native to Tlaxcala, the smallest state in Mexico, it grew up under the influence of the Nahuatl culture that is still present in the villages of the region. For this reason, he aims to preserve his ancient heritage, both the tangible and intangible. He has worked in multiple archaeological sites such as: Tepeticpac (Tlaxcala), Yaxuná (Yucatán), archaeological salvages in Cholula. It was at Tlalancaleca (Puebla) where he carried out his research project “Tlalancaleca: ceramics and regional dynamics”.
Ariel was part of the first team to join the Project Plaza of the Columns, and he has participated during the 2015, 2016, and 2019 excavation seasons. In 2018 he joined the Surface Survey Team, being in charge of verify elements in the field. In addition, it has collaborated in the analysis of the LiDAR map of the Teotihuacan Valley in search of elements that are detected through this tool, to later confirm its existence through surface survey, as well as taking samples, such as ceramics or obsidian , which are regularly at ground level. He has been the person in contact with the communities, since all the surface part of the project has been carried out under the permission and supervision of each locality of the different municipalities of the Teotihuacan Valley.
Adriana Isabel Vera Martínez (2015)
Adriana Isabel participated in the first season of this project with Front A and excavated in the heart of the Plaza of the Columns as well as along the Avenue of the Dead (La Calzada de los Muertos).
Gabriel Vicencio Castellanos(2015)
Gabriel Vicencio Castellanos is a recent archaeology graduate from the University of the Americas at Puebla. He began his fieldwork experience in 2008 with the Interaction Policy Project at the Center of Yucatan. During his three seasons with the project, he has had the opportunity to work on the site of Yaxuná as well as participate in other archaeological caving projects in central Yucatan. Several years later in 2012, Gabriel began to specialize in the analysis of obsidian, preparing his thesis “The Knives in Tepeticpac: Analysis of Obsidian in an Architectural Site in Tepeticpac, Tlaxcala.” In addition to his contributions to the tlaxcalteco project, he has helped support the mapping project of Teotihuacan, analyzed the obsidian material from a Teotihuacan workshop, and worked on the first season of excavation at the Plaza of the Columns Project.
Teotihuacan is one of the most iconic archaeological sites in Mexico. Declared as a UNESCO World Heritage site in 1987, it continues to attract a large influx of tourists every year.
The ancient city of Teotihuacan is famous not only for its monumental pyramids but also because of the entire city’s precise and deliberate grid layout characterizing a grand urban planning scheme.
The ancient city of Teotihuacan is exceptionally captivating in the eyes of the public and researchers alike, perhaps due to the many unanswered questions that continue to surround this enigmatic culture. What was the dominant spoken language back then? What did the inhabitants call their city? According to sixteenth-century Spanish records/historians, Aztecs who once visited the site were the ones who bestowed the current name of the city. In their native Nahuatl language, “Teotihuacan” means “the place where men become gods” or “the city of the gods.” Awestruck by its scale, the Aztecs believed this sacred center to be where the gods created the fifth sun.
Carlos Singüenza and Góngora carried out the first excavation in Teotihuacan during the seventeenth century (ca. 1675; Schávelzon, 1982), and it is said that this groundbreaking event marked the first archaeological excavation in America. Two centuries later, Gumersindo Mendoza, a Mexican native from the village of Aculco, State of Mexico, undertook one of the earliest systematic studies at Teotihuacan. Mendoza’s 1878 publication “Las Pirámides de Teotihuacan” summarized and analyzed the available information regarding the pyramids, such as a general description of the area (vegetation, geological features, etc.), previous and current excavations and findings, dimensions of the pyramids, as well as an interpretation about the design and use of this ceremonial center. In addition, Mendoza proposed numerous hypotheses concerning the creation and destruction of the city, as well as who were the inhabitants of the city.
In Mendoza’s day, the area where the Teotihuacan pyramids are located did not look like what we see now. In fact, most of the structures we see today were covered with soil and plants resulting from endless agricultural fields that once occupied the surrounding areas. Can you imagine what the pyramids must have looked like over 130 years ago?
To give you an idea, check out this 1878 painting by the famous Mexican painter Jose Maria Velasco:
From 1905 to 1910 Leopoldo Batres, Inspector of Archaeological Monuments, directed the first series of excavations and restoration projects at Teotihuacan. This project was set in motion to open the archaeological park to the public on September 13, 1910, celebrating the 100th year anniversary of Mexican independence. The site was inaugurated by the president of the nation, General Porfirio Diaz, and Secretary of Education, Justo Sierra, among other prominent figures of the time.
After Batres, several Mexican and foreign researchers continued intensive excavations and restoration projects in the areas surrounding the pyramids of Teotihuacan. Most notably, in the beginning of the twentieth century, Manuel Gamio and his collaborators carried out innovative investigations concerning the archaeological, cultural, geographic, and environmental setting of the Valley of Teotihuacan. The results of this first interdisciplinary work were published as a three-volume work called “La Población del Valle de Teotihuacan” (1922).
Below you can observe Gamio’s first reconstruction of the ancient city of Teotihuacan at the height of its occupation:
Between 1964 and 1970, René Millon from the University of Rochester, New York, assembled the Teotihuacan Mapping Project, integrating researchers from Mexico, the United States, and Canada. Their objective was to create the first detailed topographic map of Teotihuacan using aerial photographs and archaeological survey. In 1973 the results of the project were published in two volumes that included detailed maps of the city in unprecedented detail and magnitude, covering an area of over 20 square kilometers (or over 12 square miles).
The project produced an exceptionally detailed map of the ceremonial area of Teotihuacan where the Sun and Moon Pyramids are located. Millon used results from the archaeological survey to propose a hypothetical reconstruction of the city, indicating the location of individual structures. This project uses the same nomenclature assigned by Millon (1973) to designate areas excavated in the Plaza of the Columns and the Plaza North of the Sun Pyramid.
To learn more about Teotihuacan, please visit the National Institute of Anthropology and History’s website at INAH where you can take virtual tours of the site. If you are able to visit Teotihuacan in person, make sure you take the time to explore some of the apartment compounds (like Atetelco, Tetitla, Tepantitla, etc.) where you will encounter their elaborate mural paintings (or wall frescos) that often are missed in the rapid tour of the monumental center. They form an important corpus of information about daily life Teotihuacan.
The city of Teotihuacan is located just 40 km northeast of Mexico City, so hop in a car or on a bus, and come visit the area. We guarantee you’ll love it!
