Extremely significant examples of the deposits can be observed at Prariondo (Sassello) hiking eastwards along the Alta Via dei Monti Liguri track (close to Bric Damè).
The block streams are characterised by the presence of lobes that are both oriented along the flow direction and transversal to it. Several concentric furrows and ridges, typical of compressive flow, are visible in the frontal areas of the block fields.
The very coarse (always more than 60 cm of diameter) openwork texture of the block streams surface is characterised by blocks that dip along the borders vertically or diverging of more than 30° opposite to the flow direction.
