Tagnone
The Tagnone is a small river in the department of Haute-Corse, Corsica, France. It is a tributary of the river Tavignano. Course

The Tagnone is  long. It crosses the communes of Aghione, Aléria, Pietroso and Vezzani. The Tagnone rises in the commune of Vezzani to the northeast of the  Punta Paglia. It run east past the village of Vezzani, then runs in a generally southeast direction to its confluence with the Tavignano south of Aléria, near the mouth of the Tavignano on the Tyrrhenian Sea. The D343 road follows the Tagnone for much of its course. Valley

The Tagnone valley lies between the Tavignanu and Fium'Orbu valleys. It is smaller than these valleys and more isolated. The head of the valley is the ridge that connects the  Punta della Pinghella to the  Punta Paglia. To the north the valley is flanked by relatively low slopes. To the south it is separated from the Fium'Orbu valley by a line of heights that are above  high until the edge of the coastal plain. The villages of Vezzani and Pietroso cling to the slopes in the upper part of the narrow valley. The environment on the north-facing slopes favors forestry, and laricio pines of the Rospa-Sorba national forest grow on the foothills of Punta Paglia above the villages. The valley floor is not wide and flat enough for agriculture, which is confined to terraces around Vezzani, Pietroso and a few hamlets. The slopes and river banks are covered by maquis shrubland. There are some traces of copper mining beside the RD343. Hydrology
