Chorrillo Malo 2 is a rockshelter located in the Upper Santa Cruz Basin (Patagonia, Argentina), very close to the Andean range. Its occupation by hunter-gatherers begins ca. 9700 years B.P. and there is evidence that suggests it corresponds to an early human exploration phase of the area. Its stratigraphic sequence expands for ca. 8,000 years. New chronological data from recent excavations are presented. Changes in the stratigraphy are evaluated taking into account its sedimentary sequence, along with information about changes in the position and patina of lithic artifacts and bone weathering. New data from lithic and faunal analysis as well as the presence of structures are presented. On this basis, changes in human use of the site are suggested. The effect of changes in the shape of the rockshelter is evaluated.
