I am standing on a small beach at the mouth of the river Cuevas in Spain. The beach is studded with huge rock-formations eroded by the sea, in which caves and tunnels are carved out. It is quiet and still in this beautiful karst-landscape. The term Karst refers to all the phenomena that arise from the dissolution of limestone in water. Limestone is left over from the skeletons of (sea-)animals. These landscapes once were an ocean floor or they’re still located near the sea. A karst-landscape originates when the soluble limestone is worn out by erosion, e.g. by acid rain, and the less soluble parts remain.
