From Colle Fruscione to Tronto (path of the Ravine)

Another point of interest is Colle Fruscione: going up the hill of the cemetery you can take a small road, rather rustic, but also traveled by cars, which descends towards the Piana del Tronto.

Along this route you can admire the ravine, particular geomorphological phenomena of soil erosion, a consequence of the washout of the waters on the clayey rocks. The Italian ravine are believed to have formed, for the most part, in the Holocene and are present above all where the Plio-Pleistocene blue clays emerge. The intensive agriculture of the last decades and the need to have more and more arable land, has led to the destruction of these geological conformations in many parts of Italy. In Controguerra the gullies are in a good state of conservation and can be admired from various panoramic points, such as the belvedere of the Northern ring road or the height of Colle Fruscione.
