Summary Author: Fabio Di Stefano
In the region of Campania, Italy, it's possible to witness an oasis of the Bussento River. This river has perhaps the longest subterranean course in southern Italy. It returns to the surface in the so-called Bussento's cave, after flowing some 2.5 miles (4 km) underground. Over time, rainfall has infiltrated the limestone rock of this region creating a karst topography that on occasion permits water flowing at the surface to disappear, usually re-emerging a short distance later. However, in some cases, river flow is subterranean for more than 20 miles (32 km). Photo taken on July 19, 2019.
