A culture of northwestern Argentina during the period 700-1000 AD, located on the western slopes of the Andes, and noted for the fine quality of its arts. Decorated copper and bronze plaques and polychrome yellow and black pottery with designs of cats, dragons, humans, birds, warriors, weaponry, and trophy heads are characteristic and reflect a possible influence from Tiahuanaco. Decapitated burials are a further indication that warfare was a dominant preoccupation of Aguada. Its sudden disappearance from the archaeological record in c 1000 AD was probably the result of invasion from the east.
