New Evidence on the Formative Period in the Nepeña Valley: Preliminary Results of the First Season of Investigations at Caylán

Abstract

This contribution presents and discusses the preliminary results of the first field season of archaeological investigations at the site of Caylán, localized in the lower portion of the Nepeña Valley. Between June and August of 2009, mapping and excavation operations were carried out as part of the Proyecto de Investigación Arqueológica Caylán (PIAC). This article revises previous research realized at Caylán with the objective of underscoring the importance and complexity of the prehispanic settlement. We develop the working hypotheses, methodology and fieldwork of this first season. The preliminary analysis of spatial, architectural, and ceramic data suggests that Caylán represented the center of a new tradition that emerged in the lower Nepeña during the Late and Final Formative (800-200 BC).
