How did prehispanic farmers make a living in the hyperarid, high-altitude Atacama Desert, and how did their lives and landscapes change under different political regimes? In this paper, we discuss our ongoing project on irrigated landscapes in the interfluvial region between the Upper Loa and Salado rivers in northern Chile. Research has focused on two sites (Paniri and Topaín) with remarkably well preserved spring-fed canal and terrace systems and a residential and administrative center...
Anthropogenic Effects on Soil Quality of the Las Capas Irrigation System (2015)
A soil quality study was conducted at the Las Capas site to document and evaluate the soil productivity and hydraulic soil properties of this ancient agricultural irrigation complex. This site presents an unprecedented opportunity to study the complete configuration and evolution of the oldest irrigation system documented in the Southwest to date. Mechanical stripping permitted earthen berms around small field grids to be identified so that soil samples could be collected in relation to nearby...
Evaluating Multi-Sector Supply and Demand on Canal System 2 as a Component of a Complementary Hohokam Economy (2015)
As one of the largest canal systems in the Phoenix Basin, Canal System 2 likely served as the economic, social, and political center of life for thousands of people residing on the north side of the Salt River. Canal System 2 capitalized on a fortuitous geographic location that permitted irrigation systems and associated fields to extend miles from the river. Despite the large size of the canal infrastructure, the low population density relative to the size of the system indicates that local...
Initial Period Irrigation-based Societies in the Viru Valley, Peru (2016)
Radiocarbon dates from the sites of V-198 and Huaca El Gallo/La Gallina in the Viru Valley of Peru illustrate that the transition inland from the coast and the construction of monumental corporate architecture based on irrigation agriculture was not unique to the Supe Valle area along the Andean coastline. A second instance has been identified in Viru where it is also associated with the use of ceramics as early as 3950 years before present (2450 calibrated years B.C.). This pushes back the...
