An international team of scientists has suggested that anthropogenic pathways and geoglyphs in the Peruvian Andes could be closely tied and used by travellers as part of rituals to pacify local deities and provide safe journey, according to Cambridge University Press.
The researchers from the US and Canada studied the geoglyphs in the Sihuas River Valley pampa in southern Peru using an unmanned aerial vehicle as well as ground reconnaissance. On the basis of the data they obtained, the scientists performed spatial analysis and simulation modelling.
