The aim of the paper is to study rock distribution in order to understand changes in the hunter-gatherer societies through time. The study area is specially suited for the present purpose since resources are highly localized. Our data base includes artifacts from Cerro La China and Cerro El Sombrero localities dated between 10200 and 11200 BP and the surface collection of site1 at El Guanaco locality, which corresponds to Late Holocene times. We conclude that during the early occupations transportable toolkits were in use, while during the more recent occupation two strategies of provisioning individuals and places coexisted. Also, the presence of prepared cores is evidence of a great flintknapping ability during both moments
