Ocupaciones humanas en la margen occidental de Patagonia Central: eventos de poblamiento en alto río Cisnes

we present a synthesis of the research conducted at el chueco 1 site (cis 042). the archaeological locality is a point of great significance for understanding the peopling dynamics in a marginally occupied area of central patagonia. the temporal extension (11.500 to 2.570 cal. years bp.) and discrete occupational event superposition make the excavated context a good measure for regional human pulses and their magnitude. in this paper we define the site intervention methods and the analytical lines. we characterize the stratigraphy, the set of 14c ages, and the identified features. we also present the results of the analyses of the archaeological assemblages. finally, we discuss and synthesize the occupations recorded at the site and their regional significance.
