This article presents a descriptive approach of the lithic assemblage of the Estación Puquios site (21°0'4.48”S,68°23'12.04”O),located at 4169 masn.In the municipality of Ollagüe,Antofagasta region, northern Chile. Environmental and natural conditions of this site were favorable for the settlement of hunter-gatherers during the chronological sequence of the Archaic period (ca. 10.500-3.500 14C BP). Knapped stone tools were documented and typologically evaluated by the means of a 'virtual surface collection'.This analysis suggests that the area was integrated in mobility systems linked to the supply of local raw materials, and to discard the understanding of its use as a logistic station integrated in long-range mobility systems.
