Near the summit of Pizzo del Corvo, the plane of contact between the Val Gardena Sandstone Formation (the Upper Permian) and the underlying Dimon Formation (the Lower Carboniferous) is visible. This area is recognized as a geosite of national interest. With their characteristic reddish colour, here the pelites overlap, in discordance, with basic volcanites and stratified volcanic products. This discordance or discrepancy is a result of the uplifting and deformation to which the underlying rocks were subjected during the Hercynian Orogeny and their subsequent erosion, which occurred before the sediments that gave rise to the Val Gardena Sandstones were deposited. The discordance is also clearly visible a little further to the North-West, beneath the road near a passing/parking place.
