Sinkhole definition

Sinkhole means a surface depression caused by a collapse of soil or overlying formation above fractured or cavernous bedrock.
Sinkhole means a landform created by subsidence of soil, sediment, or rock as underlying strata are dissolved by groundwater. A "sinkhole" forms by collapse in subterranean voids created by dissolution of limestone or dolostone or by subsidence as these strata are dissolved.
Sinkhole means any depression caused by the dissolution or collapse of subterranean materials in a carbonate formation or in gypsum or rock salt deposits through which water may be drained or lost to the local groundwater system. Such depressions may or may not be open to the surface at times. Intermittently, sinkholes may hold water forming a pond.
