The extension of the Quaternary glaciations has been studied in the semi-arid Andes of north-central Chile, where the glacial modelling is striking. In the Elqui valley (lat. 30°S.), two glacial advances were identified reaching down to 3 100 m (Laguna glaciation) and 2 500 m (Tapado glaciation). In the Aconcagua valley (lat. 33°S.), moraines from three major glacial advances were found, at 2 800 m (Portillo glaciation), 1 600 m (Guardia Vieja glaciation) and 1 300 m (Salto del Soldado glaciation).The Quaternary glaciations were linked with a decrease of temperature, but more significantly with a marked increase of precipitation probably related to an equatorward shift of 5–6 degrees of the austral polar front. The results obtained in the semi-arid Chilean Andes are correlated with those recently reported from other sectors of the southern Andes.

AbstractOne of the most serious limitations in studies of prehistoric hunter-gatherer societies based on the archaeological record has been the difficulty of establishing distinctions among groups that inhabited a given area at the same time. This article suggests that, at least during a period ranging from 3000 B.C. to A.D. 1000, the Central Chilean Andes, specifically the Maipo River Valley, was occupied by two groups of hunter-gatherers that were distinct enough for us to propose that they were actually two different social units.
