The exploration of marginal spaces in Central-West Patagonia and the role of discontinuous occupation of forests and highlands

Regions with low population density, which are geographically marginal with respect to the most frequently occupied areas, are theoretically more prone to discontinuities in human occupation. This is the case in Central-West Patagonia (Chile, South America), where the discontinuities have had different characteristics and extents, some even lasting millennia. This work proposes that, given the prolonged and repeated periods of abandonment of some areas in Central-West Patagonia, its exploration is not to be considered a unique, one-time process; rather, it occurred more than once throughout its history. Because ascertaining each exploration is complex, this process can be investigated by focusing on spaces that represent the incorporation of new areas as human groups were enlarging their ranges of action. With this objective, updated archaeological data are presented in two different types of environments of the region: forests and highlands. These environments were marginal sectors that were not utilized as frequently or intensely as the valleys and where the archaeological record would be expected to preserve the actions associated with exploration contexts. The preliminary nature of data precludes defining exploratory contexts, but it is distinct in orienting its search in time and space.
