Abstract

This study investigates geospatial relationships among Late Intermediate Period (1000-1400 CE) settlement patterns within the Moquegua River drainage of southern Peru which were first identified in the 1990s by the Moquegua Archaeological Survey (MAS). A prevalence of walls and defensive locations and a largely vacant no-mans-land between down valley Chiribaya and up valley Estuquiña settlements likely evidences an increased level of inter-cultural conflict in the region during the LIP that may have continued in the Late Horizon. Using viewshed analyses in ARC-GIS, this study proposes and compares two possible chronologies to explore how Chiribaya, Estuquiña, and Estuquiña -Inca settlements interacted or competed for the surrounding river valley through their direct or indirect control of resources, and their ability to defend against each other. Through the identification of these prime factors, this study aims to understand how the placement of settlements corresponds to the larger web of social interactions.
