The following paper presents the results of a Species Distribution Model (SDM) for grassland hunter-gatherer archaeology sites in the southern Pampas region of Argentina. The goal of this exploratory model is to provide a complementary survey model for the detection of archaeological sites in this region, which will also help characterize and discuss site locations and regional distribution patterns of hunter-gatherer occupations. Even in this largely homogenous and highly dynamic landscape, SDMs can help guide archaeological surveys by identifying some environmental variables affecting hunter-gatherer decisions, and can provide insights into mobility and archaeological settlement patterns. Among the available tools for SDM, Maximum Entropy Modeling (Maxent) is one of the most widely used approaches in archaeological predictive modelling. After controlling for bias and adjustment of several modifiable parameters, the Maxent software provided a potentially effective predictive model to direct future archaeological survey and heritage management projects. The results of this research suggest that watercourses and slope were the key environmental factors influencing the distribution of hunter-gatherer archaeological sites in the southern Pampas region.

"Zanja de Alsina" (Alsina´s trench) (1876-1879) was a milestone in the border dynamics with the autonomous indigenous groups of Pampa and Patagonia. Its establishment was the initial action that led to the transformation of the frontier world into a rural one, integrated with global capitalist dynamics. This trench - 3 m wide x 2 m depth - was conceived and projected from the Ministry of War and Marine Affairs established in Buenos Aires). The trench was planned to have an ideal extension of 600 km but only 400 km were made. In this paper, and from an interdisciplinary approach, we will present the first results of the analyses carried out through satellite images, historical cartography and information provided by an archaeological work in order to locate the aforementioned trench as well as the adjacent military settlements (Machado, Alsina and Alvear - located in the northeastern part of the Pampas).
