Hunter-gatherers, landscape use and marginality thresholds in Western sectors of southern Patagonia. The case of Estancia Cristina, Los Glaciares National Park (Santa Cruz, Argentine)

Information is presented on the variability of the archaeological record at Estancia Cristina, an open Nothofagus sp. forest environment that constitutes the westernmost area between Lakes Viedma and Argentino with potential for human occupation. Three contiguous sectors were studied: the Catarina R...

description	Information is presented on the variability of the archaeological record at Estancia Cristina, an open Nothofagus sp. forest environment that constitutes the westernmost area between Lakes Viedma and Argentino with potential for human occupation. Three contiguous sectors were studied: the Catarina River valley (13 km²), the Cerro Carnero corridor (9 km long), and Carnero Bay (1 km²), which appear to have been used by hunter-gatherer groups in different yet complementary ways. The potential access routes to the Catarina River valley are discussed, and the results of the evaluation of one of them —whose entrance lies to the east, beginning in the upper basin of the Guanaco River— are presented. Estancia Cristina would have offered resources similar to those available toward the eastern forest–steppe ecotone; thus, its incorporation into hunter-gatherer circuits likely occurred because it represented an additional resource-bearing space within the extended foraging range of eastern groups. This incorporation, proposed for the late Holocene, exhibits redundancy and residential components. The study broadens the discussion on thresholds of marginality —differences in the intensity of use— of western landscapes, while contributing to the knowledge and preservation of the archaeological heritage of Los Glaciares National Park.

Se presenta información acerca de la variabilidad en el registro arqueológico de Estancia Cristina, un ambiente de bosque abierto de Nothofagus sp., que es el espacio más occidental entre los lagos Viedma y Argentino con potencial para la ocupación humana. Se trabajaron tres sectores contiguos: el valle del río Catarina (13 km2), el corredor del cerro Carnero (9 km de longitud) y la bahía Carnero (1 km2), los cuales habrían sido utilizados por las poblaciones cazadoras-recolectoras de manera diferencial y complementaria. Se discuten las potenciales vías de acceso al valle del río Catarina y se presentan los resultados de la evaluación de una de ellas, la cual tiene su vía de ingreso en el este, con inicio en la cuenca superior del río Guanaco. Estancia Cristina habría ofrecido recursos similares a los que se encuentran hacia el ecotono bosque-estepa oriental, por lo que su incorporación a los circuitos cazadores-recolectores ocurrió por tratarse de otro espacio disponible con oferta de recursos y como parte del rango de acción extendido de estas poblaciones ubicadas en el oriente. Dicha incorporación, postulada para el Holoceno tardío, muestra redundancia y componentes residenciales. El trabajo amplía la discusión sobre umbrales de marginalidad —diferencias en la intensidad de uso— de los espacios occidentales, a la vez que se incrementa el conocimiento y cuidado del patrimonio arqueológico del Parque Nacional Los Glaciares.
