Abstract

This paper presents part of the results of the geoarchaeological research carried out in the Roman camp of Via Carisa (Camino et al. 2001), in the central Asturian mountains (43°5’ 29’’N, 5°42’8” E). The research aimed to establish the evolu- tion of the landscape and its interaction with human activity. The work methodology combined geomorphological mapping, geophysical research, hand-drill coring in pond deposits and AMS radiocarbon dating. The landscape of the area results from the interaction of fluvial, gravity and anthropic processes, with the outstanding appearance of ancient mass movements and colluvium covered by small seasonally dried ponds. Radiometric dating (calibrated according Stuiver et al. 2020) of the bottom of two cores provided minimum ages of 31.960 ± 240 yr BP (36,138-35,607 yr cal BP) and 25,310 ± 130 BP (29,549- 29,179 yr cal BP) for the landslides. These data are consistent with the chronology of proglacial deposits from other areas of the Cantabrian Mountains (Rodríguez-Rodríguez et al. 2015) and suggest the possibility of paraglacial conditions (prior to 36 ka BP) for the development of the gravitational deposits.
