At this point it is possible to observe a fold in the rock, originating from the Alpine Orogenesis. As the sketch shows however, it is affected by the phenomenon of erosion. In rocks there are two types of deformation. In detail, massive rocks such as limestone deform with fracture, are friable and form cracks. Deformation without fracture however is typical of rocks with a fine consistency, such as those visible at this stop and they react in a plastic fashion, forming folds. Here you can see a rock that has a very sharp fold, with a characteristic thickness of the layers.
