Ancient pathways and geoglyphs in the Sihuas Valley of southern Peru

Abstract

Anthropogenic pathways and geoglyphs comprise two of the most recognisable pre-Colombian features of the Peruvian Andes. Although often found in close proximity, there has been no quantitative investigation of the relationships between these types of landscape features. To investigate, the authors performed spatial analysis and simulation modelling on a combination of unmanned aerial vehicle and surface reconnaissance data from the Sihuas River Valley pampa in southern Peru. The results suggest that these pathways and geoglyphs were closely tied, forming part of travellers’ rituals to propitiate local deities and ensure a successful journey.
