On the pathways. Inter-nodal archaeology in the Atacama desert Pampa (c. 7000 BP-400 BP)

We present a synthesis of our investigation into pre-Hispanic pathways of the Atacama Desert Pampa -one of the driest and harshest environments on our planet- where we have identified a variety of mobility strategies and dynamics deployed by the different communities that inhabited both the Pacific coast and the inland oases of this region. Specifically, we focus on the inter-nodal archaeological and biogeochemical data that provides direct evidence of the presence of individuals from myriad regions traversing this area from the Middle Archaic to Late periods (c. 7000 BP-400 BP). Moreover, we analyze how, beginning in the Formative Period, this multiplicity of peoples employed different mobility systems, circulation, relationships, and social exchanges to integrate this apparent “empty space”. In doing so, we discuss and reformulate the classic highland caravanning model of the Andes, which considered highland caravanning groups as the only agents promoting long-distance mobility and exchange.
