Glossary of Karst and Cave Terms

polygonal karst
1. A karst area where the surface is completely pitted with closed depressions, the divides of which form a crudely polygonal network. Especially common in humid tropical cone-karst terrain, but also found in well-formed temperate doline-karst terrain [10]. 2. A type of karst in which numerous closed depressions are separated by dividing ridges that impose a crudely polygonal appearance upon the landscape [9].
