This volume celebrates the continuing impact of the most notable contributions from by William T. Sanders, Jeffrey R. Parsons, and Robert S. Santley. In 1979, this influential work synthesized the results of the Basin of Mexico survey projects and follow-up excavations at several sites, while providing theoretical and methodological lines of research in central Mexico and generally in Mesoamerica.   More than four decades after that book’s publication, the fourteen contributions in this volume review and analyze its theoretical and methodological influence in light of recent research across disciplines. Among a spectrum of authors representing several generations are those who participated directly in the Basin of Mexico surveys—including the late Jeffrey R. Parsons—as well as those who have been actively working on recent projects in the basin and neighboring regions.   Providing a broad and multidisciplinary perspective of the present and future state of research in the area, will be of interest to Mesoamerican and Latin American archaeologists as well as geographers, geologists, historians, and specialists in the study of past environments.   Contributors: Guillermo Acosta Ochoa, Aleksander Borejsza, Destiny Crider, Charles Frederick, Raúl García-Chávez, Larry Gorenflo, Angela Huster, Georgina Ibarra Arzave, Charles Kolb, Frank Lehmkuhl, Abigail Meza Peñaloza, Emily McClung de Tapia, John K.
