Monteleone di Spoleto lies geographically in the Alta Valle del Corno, in a suggestive area full of natural beauties and important for the species of flora and fauna present. These aspects are the setting for one of the most picturesque corners of Umbria, rich in history and traditions, thanks to the presence of man since the time of the Italic peoples. The territory of Monteleone di Spoleto is mostly mountainous and is characterized by two landscape units: the first consists of the mountains of the dorsal Coscerno Mount – Aspra Mount west and Cornuvolo Mount east, the second is made up of sub flat units where the rivers flow, such as Corno River which is the main river. The limestone reliefs have rather large tops and steep slopes (picture 1); the highest peak, located southwest of Monteleone, is Aspra Mount 1654 mt. a.s.l. The Corno River has an overall length of 56 km and is the left tributary of Nera River. The substrate on which it slides is characterized by the prevalence of calcareous soils with high permeability and only on small extensions (less than 15% of the total) are present soils with low permeability.
