The region seems to be best-known for its 'San Jose' ceramics. https://www.sciencedirect.com/science/article/pii/S2352409X19304973 https://www.sciencedirect.com/science/article/pii/S2352409X1... An overview of the region & its history: http://www.condorvalley.org/explore-condor-valley/diaguita-history/ http://www.condorvalley.org/explore-condor-valley/diaguita-h... Looks like the 'Inca' element isn't a complete surprise: "In 1535 Diego de Almagro was commissioned by the Spanish crown to occupy Collasuyu, the southernmost region of the Inca empire. With 200 Spanish soldiers and 2000 Indian mercenaries from Peru, he marched over the Puna de Atacama into what are today the provinces of Jujuy and Salta."
