Description
Based on radiocarbon dating and pollen analyses of a sediment core retrieved from the shore of Naja Lake (1659'27.6"N, 9135'29.6"W), which is located near the Lacandon Forest Region in the state of Chiapas in southeastern Mexico, the authors found evidence for "a strong, protracted drought from 1260 to 730 years BP," which they characterize as "the most severe" of the record. In fact, they write that "the drought coincides with the Maya classic collapse and represents the most pronounced dry period of the last 2,000 years in the Lacandon area."
