The rock engravings of the La Pampa site, in the foothills of the Las Tunas River basin, include a set of 794 incisions, cavities and cups distributed on 25 open-air rocks. The supports and their representations were recorded to identify their internal and contextual spatial configuration, on three scales-rock, site and microregion. The site is interpreted as having a specific ritual functionality and was located in association with microregional transit routes that connected multiple activity sites located in two contrasting environments- the western mountains and the eastern piedmont oasis.
