Resumen:
The process of initial human dispersal in Patagonia involved different kinds of environments, with humans probably using least cost paths and settling in areasrich in resources. The speed of the dispersal is probably related to thedegree of homogeneity of the already known and the new lands. Most ofthe evidence for this initial dispersal can be elusive, especially taking intoaccount low human demographies,the difficulty of finding early open air occupations and the formation processes involved. Data obtained from the Deseado Massif and regions located south of the massif throughout the Atlantic slope of Patagonia indicates that humans were using different environments between ca.11,500 and 9000 yr BP, while previous chronologies are still debated. Someof these occupations may correspond to its initial exploration. Early artifactdistributions and their characteristics are analyzed along with the availabilityof high-quality rocks and the spatial and temporal environmental variability. The interconnection among different areas, possible routes and theoretical costs of transportation is modeled using GIS. The final goal is to understand the role of different resources, including lithics, in the human ranking of the land, as well as technological strategies used during human initial dispersal.
