The Maya Collapse: New Clues from Lake Sediment Cores
Streams straight from the publisher. podnod never proxies or re-hosts episode audio.
In this episode of The Mayan Civilization, Lucas and Luna explore the latest scientific findings on the Classic Maya collapse. Recent sediment core analyses from Lake Chichancanab in Yucatán and lakes in the Petén region have provided precise data on drought severity and timing. Lucas explains how a team led by Nick Evans and Mark Brenner used oxygen isotopes in gypsum deposits to identify a series of severe, century-scale droughts between 800 and 950 CE. The conversation delves into the interplay between environmental stress and sociopolitical factors—such as intensified warfare among polities like Tikal, Calakmul, and Copán—that led to the disintegration of Classic Maya civilization. Lucas also discusses the role of deforestation and soil erosion, revealed through pollen records and sediment cores from Lake Salpetén and Lake Petén Itzá. The episode presents a nuanced view: not a single collapse but a regional breakdown that struck some areas like lowland cities hard while others, like those in the Puuc region and Chichén Itzá, persisted. Listeners will learn how modern interdisciplinary research is rewriting the story of one of history's great civilizational crises.
