History of Research
The Four Valleys Archive consists of all records resulting from archaeological investigations conducted from 1983-2022 across 180km2 (ca. 70 miles2) within five distinct drainages in northwestern and western Honduras. These basins include: the Naco valley along the Chamelecon river; the lower Cacaulapa drainage, a tributary of the Chamelecon situated 9km southwest of the Naco Valley; the middle Chamelecon valley, linking the Naco and lower Cacaulapa valleys; the middle Ulua river basin ca. 40km south of the Naco valley; and, the El Paraíso valley lying 93 km to the southwest of Naco and 27 km northeast of the lowland Maya center of Copan. The materials recorded in the course of this work span three millennia (1200BC-AD1532). The archive contains data pertaining to the configurations, sizes, and locations of more than 900 sites recorded on survey along with the results of excavations at over 180 settlements and the analysis of roughly one million artifacts.
