During the spring of 1998, an El Niño event produced harsh drought conditions in much of Mexico, including the Maya area. Similar events surely occurred in the distant past. This paper reports on investigation of chronological correlations between El Niño event sequences as suggested by glacial ice-core data from Quelccaya in the Peruvian Andes, historical-severity-ranked El Niño event sequences, and historical drought documentation for the Maya area. Positive correlations between Andean ice-core data sets and historical sequences were expected to provide evidence for earlier discrete El Niño event sequences as far back as A.D. 470 that could be used as proxy data to reconstruct annual El Niño events affecting southern Mesoamerica, including the Maya Classic through Postclassic periods. Correlations of these data sets proved inconclusive, suggesting the need for alternative approaches toward reconstructing discrete El Niño sequences for the Maya area.
