Abstract The coastal archaeological sites from the sectors between Santa Cruz River mouth and the current territory of the Monte León National Park provide information about the use of local biotic and abiotic resources. The lithic technological assemblages reflect this situation: mainly local raw materials were exploited in the past, using mostly expedient technological strategies. This paper aims to enlarge the investigation about the use that was given to the different rocks in the mentioned sectors to better understand the choices that hunter-gatherers groups made in the past when selecting and using the different lithic raw materials available in the environment. It is observed that within the wide range of accessible lithologies, those that dominate the samples are siliceous rocks, dacite and basalt and that each of them shows certain differences that indicate that not of them were used in the same way. Likewise, the choice of allochthonous rocks during the Middle Holocene and then a change towards local ones in the Late Holocene is observed.
