Arriving at the point where the CAI path 154 follows the road, a detour to the right leads to the Pizzo del Corvo. A few metres to the southeast of the summit of Pizzo del Corvo are characteristic examples of basaltic pillow lavas. These sub-spheroidal forms are typical of effusive phenomena that occur in a deep marine environment. The lava erupts out onto the seabed and, solidifying, is divided into rounded blocks. This volcanic activity took place at the beginning of the Upper Carboniferous.
