II name "Cove of the Wind" derives from the violent airflow that covers it, due to the two presence feeds places to various quotas. That inferior (income tourist) and situated to m. 627 on the sea level, while that advanced, impassable one, one finds ight hundred meters more up, to beyond 1400 meters of height; the inner temperature constantly maintains on the value of + 10,7 centigrade degrees.

A air column is had therefore that of summer, being colder of the air external, and heavier, therefore provokes to the inferior entrance the famous outgoing wind (entering that advanced one). Of winter the situation footlights; since outside the nearly more and more low temperature and, the inner air, plus warmth of that lighter external and therefore, it knows them, provoking to the inferior entrance the entering wind (outgoing that advanced one). The speed of the wind and directly proportional them to the difference that elapses between the external temperature and that inner one. During the visits the airflow nearly comes completely blocked by means of the closing of one armored door.

The cave is located in one of the more colorful zones of the Alps Apuane, is between the European cavities of greater scientific interest. The great variety of aspects and the immensest fenomenologia, make of this cove a true natural encyclopedia of speleology and deep carsica morphology, whose aspects come illustrates with precision and competence to you from the guides.

Covering comfortable paths, all can be observed the evolutionary manifestations of the cove, from the small split that are some to the origin to the great vertical abysses, from empty the lead as soon as dug from the water to the ancient fossil galleries, all adorned from splendid stalatti to you policrome, exiles drape traslucent, candid taps and stalagmitiche guglie. The water, absent in surface, abound in all the cove, where underground rivers, cascades are met, sifoni, smalls lake and pools of overflow. The concretions are all alive ones, that is in increase, always covered from a water veil that revive the exalting colors.

Approximately 200 million years ago, on the bottom of a sea that we could make to correspond to puts into effect them Tyrrhenian, enormous amounts of shells of shells, coralline formations, skeletons of fish, sands, slush and carbonate of hasty soccer chemically for evaporation of the water began to deposit themselves

These detritus, although in various amounts and compositions, continued to accumulate, layer on layer, in order at least 170 million years, being formed one mass of thousands of meters of thickness. The enormous weight of such I accumulate I slowly provoke to the jam and the cementation of several the elements, transforming it in limestone cliff.
Around twenty million years ago, strong pushes (orogenetici movements), tied to the drift of the continents, provoked the raising of this full of rocks mass that, fracturing itself intensely because of the powerful sollicitations received, emerged from the sea, and formed put into effect them slowly them mountains.
The piovana water, falling on the crepacciata surface of the mountain, came immediately swallowed in the sottosuolo, where vary rivoli of water joined in order to form those underground streams, those torrents and those rivers that, covering for the million years fissures, them have progressively widened, transforming them in that driven in net of cunicoli, galleries, pools and knows them that they constitute the underground complex of the "Cove of the Wind"
