The geomorphological analysis of the coastal sector of Pan de Azúcar National Park (Chile) allows describing several stages in its recent geological evolution, mainly controlled by the climate, variations in the sea-level and the uplift of the Cordillera de la Costa. The first phases refer to the formation of three generations of marine terraces, while the last stage involves the Present Interglacial, the establishment of the current sea-level, the formation of the Holocene marine cliff and the development of active forms, with predominance of the eolian and fluvial/alluvial processes on this coastal segment of the southern Atacama Desert. For the first time, the occurrence of a low marine terrace that crops out near current sea-level is described in the study area. It has been dated in ~44000 years and associated with the MIS-3 highstand. This age corroborates the beginning of a cycle of accelerated tectonic uplift, with rates of ~ 1 m/ka, recently proposed for northern Chile that would continue until today.
