LEGOUPIL, D. CERRO CASTILLO ROCKSHELTER OCCUPATION: A RESIDENTIAL SITE IN A PANORAMIC VIEWING-POINT. Magallania [online]. 2009, vol.37, n.1, pp.47-60. ISSN 0718-2244.  http://dx.doi.org/10.4067/S0718-22442009000100005.

The end of the former Lago Toro glacier basin, at the entry of Torres del Paine park, is a rich area with eroded archaeological sites, especially at the edge of rivers. These bear witness to an important demographic expansion in the zone, which, however, little known and poorly dated. An archaeological site discovered in a rock shelter at Cerro Castillo (San Roman and Morello 2003) might document these groups, from the 5° millenium AP. With this purpose, a second test pit was done in year 2006 by the archaeological French mission, allowing a palaeoenvironmental study of the site (Bertrán 2009, Solari 2009, both in this volume). More than 10.000 lithic materials were studied (Langlais and Morello 2009), and a first archaeozoological analysis was done (San Roman and Morello 2003; Prieto in Legoupil and Bertran 2006). These studies confirm the strong informative potential of this rock shelter which, by offering visual control of the immense valley, represents an exceptional where about for hunters. Nevertheless evidence of hunting activities is scanty (few projectile points and no bolas), instead the site shows characteristics of a habitation camp, with important domestic activities that testify the production of stone flakes (often used) and the abundance of sidescrapers, end-scrapers and knives in the proximity of combustion areas. In spite of postdepositional disturbances, common in such contexts, and of the rich palimpsest of occupations observed, it is possible to distinguish broad stages of human occupation in the site. Man installed himself 4500 years ago, in the first moments of sedimentary unit IV, a humid period that favored the development of woodland cover, which is also recorded in unit III before disappearing in the final stage; where the current steppe predominates. Within a common technological environment, different technical modifications are noted (probably of functional origin): for example, abandon sent of the use of obsidian in favour of chalcedony, and the replacement of side-scrapers for retouched flakes anwd end-scrapers, as dominant tools. The distribution of remains, the presence of fireplaces and the use of blocks, the latter possibly arranged intentionally, highlight the palaeoethnographic potential of this site. It might clarify the lifeways of terrestrial hunters in the region and offer a well controlled stratigraphic column coverig the second half of the Holocene.
