The sociopolitical reorganization of the Maya that took place during the Terminal Classic (AD 850–1050) has been interpreted as being correlated to regional environmental change, specifically drought. However, few climate reconstructions come from the southern Maya lowlands where the decline occurred during this period. While most paleoenvironmental reconstructions lack a local, site-related signature and instead reflect regional trends, stable isotope analyses of herbivore faunal remains have...

This is an abstract from the "SAA 2024: Individual Abstracts" session, at the 89th annual meeting of the Society for American Archaeology. This presentation provides a practical introduction and toolkit for investigating relationships between climate and human behavior. The urgency of addressing the problems of our warming world is beyond the responsibility or exclusive domain of climate scientists or specialists – it is a shared human responsibility. Public or scholarly contributions do not...

This is an abstract from the "Migration and Climate Change: The Spread of Mississippian Culture" session, at the 84th annual meeting of the Society for American Archaeology. Tree-ring reconstructions of cool- and warm-season moisture reveal several multi-decadal droughts that impacted the northern Lower Mississippi Valley between AD 1250 and 1450. These chronic droughts contributed to the regional abandonments and population migrations southward out of the Cairo Lowland and adjacent areas...

A new drought atlas has been developed for subtropical North America, including the entire Republic of Mexico.  This Mexican Drought Atlas (MXDA) is based on 251 tree-ring chronologies, including 82 from Mexico and another 169 from the southern U.S. and western Guatemala.  The new reconstructions of the Palmer Drought Severity Index for June-August provide a more detailed estimation of decadal moisture regimes since AD 1400.  Droughts previously identified in a subset of chronologies are...

This is an abstract from the "2023 Fryxell Award Symposium: Papers in Honor of Timothy Beach Part II" session, at the 88th annual meeting of the Society for American Archaeology. Geologists and biologists work with archaeologists to address compelling questions about cultures of the past. Earth scientists who study tree rings, ice cores, speleothems, and lake sediment cores can provide information about the paleoclimatic and paleoenvironmental contexts in which ancient cultures developed,...

This is an abstract from the "SAA 2021: General Sessions" session, at the 86th annual meeting of the Society for American Archaeology. Far from being limited to maize, beans, and squash, the ethnographic Maya are known to make use of 497 species of food plants indigenous to the Maya Lowlands. This study presents initial results of determining “food values” based on nutritional content for these plant species, and the methods used to determine the values. The results have significant...

Recent dating work has led to revision of regional political chronologies in the Guatemala Highlands. In particular, key Middle and Late Formative phases now date as much as 300 years later than previously believed. This reanalysis brings these phases in line with significant environmental conditions stemming from volcanism and drought. In this paper, we present new high-precision chronologies for these environmental records, and compare these records against regional political chronologies in...

In The Great Maya Droughts in Cultural Context, contributors reject the popularized link between societal collapse and drought in Maya civilization, arguing that a series of periodic "collapses," including the infamous Terminal Classic collapse (AD 750), were caused not solely by climate change-related droughts but by a combination of other social, political, and environmental factors. New and senior scholars of archaeology and environmental science explore the timing and intensity of droughts...

This is an abstract from the "Migration and Climate Change: The Spread of Mississippian Culture" session, at the 84th annual meeting of the Society for American Archaeology. Based on artifact styles, regional archaeologists in the 1940s first proposed movement of Mississippian people from the Middle Cumberland Region to the Great Valley of East Tennessee. Lacking absolute dating techniques, these researchers had limited understanding of the timing or contemporaneity of the archaeological...

Over the last 20 years, a number of studies have provided evidence for a "drought" in the Maya Lowlands between the 8th and 10th centuries. Researchers have argued that a higher water table in the northern lowlands allowed agricultural practices to continue in the north, while sites in the south suffered from the drought. This paper will examine the relationship between population changes and climatic changes in the Maya Lowlands. The nature of the water table and the agricultural practices of...

Water and power are foundational building blocks for the continual development of the greater Phoenix metropolitan area. On March 18, 1911, Theodore Roosevelt Dam was dedicated and the cornerstone was set for dependable water and power to the Salt River Valley. The vital resources from the dam now reliably serve one of the nation’s largest metropolitan areas. Standing for More Than a Century simultaneously celebrates Roosevelt Dam’s centennial and illustrates significant events in the Valley’s...
