Stones that rise up
Normalmente il concetto di “sasso” è legato al suo peso:
“Pesante come un sasso”, “Cadere come un sasso”, “I sassi nell’acqua vanno subito a fondo”….Infatti non accade quasi mai che in natura i sassi possano salire, soprattutto su lunghi tratti aventi forti dislivelli.
Eppure nella Grotta del Vento ciò è accaduto, le prove sono inconfutabili e documentate fotograficamente…
Normally the concept of “stone” is associated with its weight, …“heavy as a rock”, “drop like a stone”, “stones in water go straight to the bottom”…. And in fact it almost never happens in nature that stones can rise up, especially over long tracts with big differences in height.
And yet in the Grotta del Vento it has happened, the proof is undeniable and documented with photographs. #grottadelvento garfagnana #curiosità #funfacts

Looking closely at them one can observe that while the formations which surround them have a smooth shiny surface, the bottom and the sides of these pools…

Corrosion from sulfuric acid
On 22/08/17 we published an article about boxworks, which are the result of the corrosive action that the carbonic acid exerts on the dolomitic limestone of the first itinerary, isolating a network of fine layers of calcite. This time let’s talk about other phenomena of corrosion, made on the same type of rock a few…

Vein structure from evaporation
On first sight they look like boxworks but they are not. While boxworks are very thin layers of calcite sticking out that have resisted to the corrosion of the dolomitic limestone which surrounded it, these protruding veins, clearly visible in the part of the tunnel which separates the natural entrance of the cave from the…

The Stiffe cave (San Demetrio de’ Vestini – AQ)
La Grotta di Stiffe è la risorgenza attiva di un sistema sotterraneo che inizia dagli inghiottitoi situati 600 metri più in alto, sull’Altopiano delle Rocche, in provincia dell’Aquila. Attrezzata con comodi sentieri, è caratterizzata dalla continua presenza di un copioso fiume sotterraneo, interrotto in due punti da fragorose cascate che precipitano nelle acque tumultuose di piccoli laghi sotterranei.
