Abstract Geomorphological investigations have revealed the presence of a "periglacial" accumulation form, in places looking like glacis, which was previously described as a landslide body. On the contrary, its origin is to be attributed to a periglacial morpho- climatic environment, with no or little vegetation on the slopes and gelifluction, flow and mass movement processes, favoured by the seasonal presence of frozen soil and cryoturbation and frost shattering. In this way, a chaotic detrital cover was formed, made up of calcareous-arenaceous debris mixed with broken argillite layers in a pelitic matrix. This material covered in a more or less homogeneous way the slope of the San Andrea Pelago area, obliterating most of the pre-existing morphology. The onset of Holocene fluvial erosion has cut through this periglacial deposit and in some places also the underlying bedrock, forming scarps up to 70-80 m high. It is here proposed, in a formal way, to ascribe the term "Tagliole" to the last glacial expansion occurring in this sector of the Apennines, considering the copious presence of these typical landforms in the valley bearing the same name.
