Gruta del Indio


Gruta del Indio is a rockshelter site overlooking the Río Atuel valley just south of the present-day city of San Rafael. The 110 cm thick deposits in this cave site span the period from the Late Pleistocene to the Late Holocene (Gil et al. 2005). Maize was recovered from the upper layers and one sample was dated (Lagiglia 1999).
