The karstic phenomena

A long, deep incision with steep walls, a dozen meters high above the valley. These are not margrave injuries, deep grooves embedded in the limestone rock with the passage of time. Small Mediterranean canyons, which have  also become a UNESCO world heritage site since 2005. While hiking or trekking, you can venture out and take a tried and true trip back in time. In the valley, you can admire the rocks that date back to the Late Cretaceous, overlapped with Pliocene-Pleistocene deposits. On the highest portion of the slopes, you can still observe the “Sub-appennine clays”, dating back to the early Pleistocene, along with the “sandy-gravelly terraced sediments” from the lower-middle Pleistocene. A thousand years have passed, and much time has elapsed, a time that has transformed the landscape, but that has not, fortunately, changed its history.
