AbstractAs a result of five field seasons in the Campo del Pucará, Prov. of Catamarca, the Alamito culture, dated in the fourth century A.D., is one of the best known archaeological cultures of the Valliserrana subarea of northwestern Argentina. The 50 sites excavated show only slight variation in subsistence (essentially agricultural), technology, ceremonial structures, burial pattern, settlement pattern, and inferred social organization. Close affiliations are evident with the Ciénaga, Condorhuasi, and possibly Tafí cultures of Argentina; further afield, similarities can be observed with the Megalithic culture of Bolivia, Chiripa and Titicaca Basin complexes, and more remotely with Peru.
