Abstract

Karst is an irregularly shaped area of land where underground drainage dominates and has resulted in dissolving the bedrock to form distinctive surface and subsurface features. Karst predominately develops on lands underlain by soluble bedrock such as limestone and dolomite, but can also form in marble, gypsum, and halite. Due to differences in climate, cover, rock type, hydrology, and geologic structure, some areas show significant expression of karst development at the surface, and others show no obvious signs at all. Chemical solution of the bedrock by groundwater leads to the formation of open passageways into and through the subsurface. The degree of development of these features varies greatly from one region to another.
