“…The study of strontium isotopes as a proxy for spatial scales of human paleomobility is articulated with multiple lines of evidence in a biogeographic research framework that seeks to understand the movements of people, flow of material objects, and circulation of information across and along the rugged landscape of the Patagonian Andes. An ongoing macro‐regional program of geoarchaeological and geochemical characterization of Andean and extra‐Andean obsidian sources allows tracking lithic provisioning, use, and discard (Barberena, Fernández, et al, 2019; Fernández et al, 2017, 2019; Rindel et al, 2020). We are also conducting a large‐scale survey and morphological characterization of rock art in northern Neuquén Province, which suggests the existence of a sphere of exchange of information that ties distant areas (Barberena, Romero Villanueva, et al, 2017; Romero Villanueva, 2019; Romero Villanueva et al, 2020; see also Campbell et al, 2020; Martínez et al, 2017).…”
