Settlement pattern
The Aconcagua built their dwellings on valley floors and riverbanks, forming small groupings of 10 residences or less. These were detached from each other and built in the quincha style, which used a combination of mud, straw and cane. The people who lived in these small settlements were likely members of the same kinship group. Some of these settlements were directly associated with the exploitation of specific resources: those on the coast were focused mostly on collecting marine products, while those in the mountains carried out copper mining.
