canyon exploring with Michele Angileri
Fosso di Fibbianello
Everywhere, limestone rocks mean karst phenomena. The fissures in rock are widened by rainwater, which more and more easily penetrate underground, digging tunnels that form networks that become wider and more complex over the millennia. Often as the water digs, the mountains continue to rise, and then water penetrates deeper leaving the old tunnels and digging new ones. If the mountains still continue to rise, fragments of these ancient ones galleries may emerge on the surface turning into gorges that are "caves without a ceiling". It also happens that fragments of "ceiling" remain to testify the hypogean origin of the canyon.
All this happens at Fosso di Fibbianello. The spectacular stone arch and the abundant spring that gushes a few meters down leave no doubt about the karst origin of this Mediterranean canyon immersed in the gentle landscape of the Tuscan Hills.
I remember ...
Near the gorge is one of the oldest trees in Italy: the Olivone di Fibbianello. An olive tree which, they say, is more than 2000 years old!
A quick dive into infinity.
