The North Patagonian west coast shows signs of sporadic occupations at least between 6000 and 900 years BP. In this paper, we present the results of a first approach from lithic taphonomy to Alero 2, located in the archaeological site of Punta Pórfido. The excavations carried out suggest that the rock shelter has a complex formational history, dominated by endogenous processes, such as weathering and rockfall processes that, together with the presence of potential pseudo-artifacts, pose a relevant research problem. The present work uses conceptual and methodological tools derived from lithic taphonomy and experimental archaeology to discuss the process of formation of the lithic record.
