Abstract New results obtained in the Nothofagus forest around El Chaltén town, close to the Southern Patagonian Ice Field, are introduced. The environment is highly seasonal and the landscape configures a dead end. Excavations at shelters in boulders -La Lagunita-La Fisura, Alero 1 and Alero 2 archaeological sites- provide information on lithic technology and archaeofauna that was complemented by rock art surveys and the recording of isolated finds. The archaeological record shows low intensity use, activities related to artifact maintenance and the archaeofauna evidences marrow consumption. All sites have zoomorphic rock art motifs that do not suggest marked differences in their execution time. The marginal and logistic use of the forest by hunter gatherers supplied coming from the Eastern steppes is proposed. Two radiocarbon dates circa 400 years BP show the late integration of this environment within hunter-gatherer systems of the Lake Viedma Northern shore. An initial comparison on forest use with the Southern margin of the lake and neighboring basins (Lakes San Martín and Argentino) points to different marginality thresholds.
