Different approaches to the analysis of archaeological evidence in the center of Argentina, particularly in La Pampa province, account for the existence of east-west corridor that favored the interaction, mobility and a social dynamic between the current territories of Chile and Argentina (36º to 39º LS). Processes of interaction and conflict accounted during Late Holocene, that were shaped in the nodal spaces, but that certainly had geographical settings in the internodal regions of this broad corridor. The information originated through archaeological research and the analysis of ethno-historical documents allow us to propose that during the Late Holocene (last 2000 years) a corridor of social interaction between groups of hunter-gatherers was engendered, reaching to trans- Andean sectors and contributing to territorial integration of the Wall-Mapu. This integration included conflict and etno-genesis processes. The actual ethnic map of La Pampa province is the result of these historic accounts.
