Chiascio in the context of Scheggia Pass
The Scheggia Pass is a pass in Italy that marks the division between the Central and Northern Apennines. It is in northern Umbria and lies between Gubbio and Cagli at 632 meters. It opens up as a natural plateau near the border with the territory of the municipality of Cantiano, in the province of Pesaro and Urbino.
Although it is on the border between Umbria and Marche, it does not represent a watershed between the Adriatic and Tyrrhenian sides: in fact, it connects the Burano valley (Metauro basin) to the Sentino valley (Esino basin). The watershed is located further south, between Scheggia and Costacciaro, dividing the Sentino valley from the Chiascio valley.
