Vrica and Stuni: the ravines
About four kilometres south of Crotone is in an area of great scientific value, characterized by the presence of ravines: particular forms of erosion created by the atmospheric agents, above all by rain water. The importance of the area is due to its special clay rock formations, which have become known in geological literature “Vrica Sections”.
In fact, on behalf of the entire international scientific community, international organizations have agreed that this place represents the boundary between rocks formed in two different yet subsequent geological periods, and is thus used to define a standard for distinguishing the transitions between different eras.
In scientific terminology, this era is known as the Pliocene/Pleistocene, for which it is a sort of internationally recognized geological photograph that shows an epochal mutation that took place nearly 2.5 million years ago.
By reading the walls of the ravine, expert eyes are able to identify a stratification that bears witness to the passage from one era to the next. These hills, therefore, are of enormous geological significance, and also provide for a highly suggestive landscape:the environment is similar to that of the Central American Desert, with thorny shrubs sprouting from the ground here and there, blossoming in the springtime with intensely aromatic flowers.
