          Abstract

          Resumen: La costa oeste norpatagónica presenta indicios de ocupaciones esporádicas al menos entre los 6000 y 900 años AP. En este trabajo se presentan los resultados de un primer acercamiento desde la tafonomía lítica al Alero 2 ubicado en la localidad arqueológica de Punta Pórfido. Las excavaciones realizadas sugieren que el alero posee una compleja historia formacional, dominada por procesos endógenos como la meteorización y la caída de rocas que, junto con la presencia de potenciales pseudoartefactos, plantean un relevante problema de investigación. El presente trabajo utiliza herramientas conceptuales y metodológicas derivadas de la tafonomía lítica y de la arqueología experimental para discutir el proceso de formación del registro lítico.

          Abstract: 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.

            Downslope Movement and Archaeological Intrasite Spatial Analysis

            Erosion can produce heterogeneous distributions of cultural materials of differing densities, weights, and shapes within an archaeological site. A large, provenienced surface collection from a preceramic site in highland Peru is examined for evidence of downslope movement as an explanation for observed heterogeneity in artifact distribution. Statistical methods of spatial analysis are used to define the extent of movements of surface materials in this site. For this particular area of Peru, critical angles for downslope movement will limit the site areas in which analysis of horizontal distributions can be expected to produce culturally significant information.
