| Sumario: | This paper discusses cultural (material) and environmental evidence for the Pleistocene-Holocene transition in the Andean Central Patagonia. Fossil pollen analysis in Laguna Shaman, geomorphologic observations and archaeological surface surveys in upper Cisnes river basin and stratigraphic excavations at one site. El Chueco are integrated, summing up the information recently gathered by our research team. The exposition of this data has twofold aim. On one hand, it is intended to shape an image of the scenery the first occupants faced while initially exploring the region. On the other, we try to set the environmental and palaeoenvironmental constraints and possibilities for the survival of the archaeological record of Pleistocene-Holocene age. Finally, the evidence is discussed in the frame of the chronological data for the wider Central Patagonian archaeological record.
