El Chal [SEP] Introduction
El Chal is a pre-Columbian Maya archaeological site located in the upper San Juan River valley of the southeastern Petén Basin region, Guatemala. The site is situated approximately to the north of the modern town of Dolores, near the contemporary village settlement of the same name, lying some to the south. El Chal was occupied from approximately 300 BC through to 1300 AD (from the Late Preclassic through to the Early Postclassic Periods of Mesoamerican chronology), although some Middle Preclassic activity has been identified in the acropolis. The Late Preclassic occupation of the city was concentrated around an E-Group ceremonial complex some north of the later site core.
