These are called solution sinkholes. These rocks dissolve when attacked by rainfall or groundwater that is acidic. Solution sinkholes have sides that vary from gentle slopes to almost vertical, while their shapes include saucer-like hollows, cones, cylindrical potholes and shafts. Streams or rivers may enter a sinkhole and disappear underground.

The department’s Missouri Geological Survey provides assistance to citizens by performing geologic evaluations to aid in determining if a collapse is attributed to a natural karst feature, such as a sinkhole, or is associated with the failure of a man-made feature. A sinkhole is a depression in the ground that has no natural external surface drainage. Basically, this means that when it rains, all of the water stays inside the sinkhole and typically drains into the subsurface. Sinkholes are most common in what geologists call, “karst terrain.” In the preliminary report, the Bureau of Economic Geology, a research unit at the University of Texas, said the new sinkhole has a diameter of about 230 feet (70 m) and is about 30 feet (9 m) deep.The Red Lake sinkhole in Croatia. A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. The term is sometimes used to refer to doline, enclosed depressions that are locally also known as vrtače and shakeholes, and to openings where surface water enters into underground passages known as ponor, swallow hole or swallet. Article Vocabulary A sinkhole is a hole in the ground that forms when water dissolves surface rock. Often, this surface rock is limestone, which is easily eroded, or worn away, by the movement of water. In a landscape where limestone sits underneath the soil, water from rainfall collects in cracks in the stone. These cracks are called joints.Representative observations indicating sinkhole formation by dissolution of a buried salt layer within sediments of mudflats.
