In 2012 Alden Yépez carried out a survey on the southern slopes of the highest mountain in Ecuador, the Chimborazo, providing new insights into the nature of twelve archaeological sites. These sites are close to a historical pathway that was tracked by GPS. This path gives access to a group of sites which the ancient Inca most probably used for worshipping. This path serves as a reference for identifying the appropriate method to reconstruct past movement patterns. For additional verification of the results, younger pathways of the same region were analyzed. The early movement patterns derived from this analysis are used to create an accessibility map. However, one group of sites in the vicinity of a cave is not well accessible. We assume that visibility issues played an important role in this case.
