Extensive description and analysis of the archaeological settlement data collected in the late 1960s and early 1970s in the Chalco-Xochimilco Region in the Valley of Mexico.

In this work, the authors interpret archaeological data on roughly 3000 years of human history in the Valley of Oaxaca, from roughly 1500 BC to AD 1500. They integrate information on settlement patterns, political and social organization, artifact distribution, and more.

This report is a descriptive tabulation of settlement pattern data collected by University of Michigan projects in the Valley of Mexico between 1967 and 1973. Data is presented in tabular form for hundreds of sites, including information on environmental zones, elevation, rainfall, soil depth, phases of occupation, and more.

An archaeological study of ancient settlement patterns in Peru’s rugged and diverse central highlands.

Scientists have long speculated on the impact of extreme natural catastrophes on human societies. Archeology and Volcanism in Central America provides dramatic evidence of the effects of several volcanic disasters on a major civilization of the Western Hemisphere, that of the Maya. During the past 2,000 years, four volcanic eruptions have taken place in the Zapotitán Valley of southern El Salvador. One, the devastating eruption of Ilopango around A.D. 300, forced a major migration, pushing the Mayan people north to the Yucatán Peninsula. Although later eruptions did not have long-range implications for cultural change, one of the subsequent eruptions preserved the Cerén site—a Mesoamerican Pompeii where the bodies of the villagers, the palm-thatched roofs of their houses, the pots of food in their pantries, even the corn plants in their fields were preserved with remarkable fidelity. Throughout 1978, a multidisciplinary team of anthropologists, archeologists, geologists, biologists, and others sponsored by the University of Colorado's Protoclassic Project researched and excavated the results of volcanism in the Zapotitan Valley—a key Mesoamerican site that contemporary political strife has since rendered inaccessible. The result is an outstanding contribution to our understanding of the impact of volcanic eruptions on early Mayan civilization. These investigations clearly demonstrate that the Maya inhabited this volcanically hazardous valley in order to reap the short-term benefits that the volcanic ash produced—fertile soil, fine clays, and obsidian deposits.
