The objective of the ARIMAS project is to understand the modalities of human occupation of the region and human exploitation of its vegetal, animal and mineral resources within a refined chronological and palaeoenvironmental frame. The preservation of open-air lithic scatters alongside shelter and cave sites in a relatively constrained area of research provides an excellent opportunity to study the movement of past human groups across the landscape. By examining the interplay of open-air lithic scatters, raw material outcrops and shelter sites, we have a rare occasion to explore how different site types change, continue and interact across time and space. Our work at Arimas Farm will be accomplished according to three phases.
