Resumen:
At the time of the first human exploration of Ultima Esperanza, Chile, swift climatic and environmentalchanges were taking place. The retreat of the Pleistocene glaciation and the formation of an ice-dammedproglacial lake east of the Cordillera created adequate conditions for human colonization. Volcanic activity,climatic oscillations, and concomitant floristic changes defined the environment encountered bythe first hunteregatherers arriving to Ultima Esperanza. The oldest archaeological evidence wasdeposited sometime between 10,930 and 10,410 BP and point to ephemeral occupations. The evidencefrom Ultima Esperanza is compared with other areas where early human presence was detected inFuego-Patagonia. The hypothesis that the early human occupations at Cerro Benitez-Lago Sofía resultedfrom logistical exploitation from Pali Aike is introduced
