Summary

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 order to suggest how cultural developments may have been influenced by these factors.
