Abstract

The aim of this paper is to evaluate potential sectors of pedestrian fording of the Santa Cruz River (Santa Cruz province) by modeling least-cost paths in the context of Geographic Information System (GIS). Different variables are utilized, such as: slope, basaltic cover, water sources, depth levels of the Santa Cruz River, and the presence of banks and islands. We evaluate optimal paths among the following archaeological sites located in the Santa Cruz River basin: La Laurita 1 (upper basin, northern margin), Bi Aike 3 (middle basin, northern margin), Yaten Guajen 12 (middle basin, northern margin) and Chorrillo Malo 2 (upper basin, southern margin). These sites share late Holocene chronologies and the presence of black obsidian lithic artifacts. This is a raw material that, according to available evidence, originates from areas located to the north of the basin. The results of the human circulation models are compared with information that was not used for the generation of this model, such as the distribution of surface and stratigraphical archaeological record documented for the area, as well as data obtained from historical accounts.
