Abstract The present paper attempt to improve the knowledge of human biogeography in arid environments and, understand the phases of settlement in relation to human demographic trajectories. In this framework, new archaeological information of the El Corcovo area is presented, located in Monte Surmendocino / Nordpatagónico. The field-works that contemplated transects, archaeological excavation of a site and the surveying of rock art of three others are detailed. The results indicate the beginning of occupations around 1900 years 14C AP and a change in the pattern of mobility around 600 years 14C AP. Both situations are consistent with the existing relative chronological estimates for the rock art of the area. Based on a regional demographic model for Monte area, the results show two pulses of increase in the human signal that correspond chronologically with the initial date of occupation estimated for the area and with the date obtained for the proposed change. By associating these pulses with significant falls in the phyto-geographic sector of Patagonia, alternative explanations on population dynamics are postulated.
