What is Karst?
Karst is a form of limestone erosion that gives the landscape a rugged appearance. The name comes from the Kras region in Slovenia.
Underground waters have dug into the rock, resulting in the formation of chasms. The losses of water from the Bandiat and Tardoire rivers feed the resurgence of the Touvre, near Angoulême.
