Resumen
Alluvial fans are typical geomorphic features of arid and semiarid mountain areas. Most archaeological sites in Santa María valley (NW Argentina) are located on this kind of landform. The aims of this paper are to describe the geomorphological context and assess the state of conservation of four archaeological sites on the piedmont of Sierra de Quilmes (NW Argentina) from a geoarchaeological perspective; to diagnose the geomorphological processes affecting the sites over the last 50 years; to assess their vulnerability and conservation hazard; and to propose some corrective measures. By mapping with remote sensors (e.g., drones, aerial photographs, and satellite images) and conducting field surveys, we found that most archaeological sites are set on the H1 and H2 units of the alluvial fans. and that their geomorphological dynamic has increased in the last 50 years. The main active processes are debris flows, overflows, and mudflows, accompanied by the development of rills, sheetflood, and aeolian deflation. Human impact is also severe. The four sites need mitigation measures and a structured management plan. To date, no studies of this kind have been done rin the region, although one of the sites has been partially reconstructed for touristic purposes.
