Resumen:
Early human occupations at the southernmost end of the Deseado Massif -La Gruta area- date from the Pleistocene/Holocene transition and are, according to the available evidence discontinuous in time. A little bit after that time, the presence of Mylodontidae and guanaco has been recorded at the area, although not clear evidence of strict contemporaneity in time and space between extinct fauna and humans have been found. Here we will discuss stratigraphic and surface evidences related to this early presence. Human inhabitants were transporting not only obsidian?from distances of ca. 175 km to the northwest?but also translucent chalcedony, available at distance of 25 km to the north. Preforms of projectile points recovered on surface and made on chalcedony, seem to have similarities in design, in one case, with an early point recovered at the south of the Magellan Strait, more than 400 km to the south. In other cases, they can probably be related to the range of variation of fish-tail projectile points, recovered in Patagonia, suggesting the existence of more than an early design of projectile points.
