Resumen:
Lithic artifacts, in conjunction with other evidence, provide useful information about the way in which humans have explored and occupied the Patagonian landscape. At the southern Deseado Massif, the distance between the two areas with early dates is ca. 60 km which, according to ethnographical information, is within the home range of hunter-gatherers living at these latitudes. It must also be noted that there is variation in the availability of raw material for lithic tools near Casa del Minero 1 and Cueva Túnel which, in comparison with that recorded near La Gruta, is of better quality. This can be used to suggest that the earliest deposits of La Gruta 1 correspond to a logistical occupation in the context of human exploration of new space. We understand this occupation as related with nearby places in the North. Supra-regional evidence shows that this is a time at which radiation is actively taking place, probably in accordance to a general warming trend. More extensive sampling at La Gruta area and the intermediate space to the north is needed in order to discuss this hypothesis.
