Abstract

A geophysical survey analysis is carried out using electrical resistivity tomography (ERT) in the Sopeña shelter (Asturias) and its immediate area. The shelter contains an interesting Upper Middle Palaeolithic and Early Upper Palaeolithic site, revealed in an archaeological test pit up to 3 metres deep without having reached the bedrock. Its current entrance is protected by large blocks fallen from the ledge, covered by thick stalagmitic flows. This arrangement possibly testifies to an original position of the innermost human occupation zone, inside a larger cave. Through this analysis we have located several possible sedimentary fills at a certain depth on the outside of the shelter. This opens up the possibility of sampling these fills in the future, in search of possible older occupation levels.
