This can be described as a distinct landscape which is made when underlying rocks either dissolve or change their shape. This can lead into the formation of caves, fishes, underground wells, jagged hills, river beds and other types of terrain. When we notice such a topography it normally indicates that water is close to soluble bedrock which might include dolomite, gypsum and rock salt. This kind of topography is found throughout the world but it's particularly important mapping site includes locations such as mammoth cave and the fisher ridge cave system in Kentucky and the Friars whole system in West Virginia.
