Karst topography is a geological formation shaped by the dissolution of a layer or layers of soluble bedrock, usually carbonate rock such as limestone or dolomite, but also in gypsum. [1] It has also been documented for weathering -resistant rocks, such as quartzite , given the right conditions. [ 2 ]
Global distribution of major outcrops of carbonate rocks (mainly limestone, except evaporites). The English word karst was borrowed from German Karst in the late 19th century, [6] which entered German usage much earlier, [7] to describe a number of geological, geomorphological, and hydrological features found within the range of the Dinaric Alps, stretching from the northeastern corner of ...
The Woodville Karst Plain is a 450-square-mile (1,200 km 2) karst area that runs from Tallahassee, Florida, U.S. to the Gulf of Mexico separated by the Cody Scarp.. This karst plain contains the Wakulla-Leon Sinks Cave System, the longest surveyed underwater cave in the United States, extending 32 miles (51 km) and ranking #57 among the top 100 longest caves in the world.

“We have over 4,000 reported karst features and several thousand caves,” Selig said. “We’re still finding new caves all the time and there’s still a lot to learn about Indiana’s caves.”
The Mitchell Plain is a karst area in Indiana of relatively low relief. The extensive underlying cave system developed in Mississippian age limestone bedrock. Surface drainage is rare due to most streams in the area disappearing into caves or joints within the rock.
The Floridian peninsula is a porous plateau of karst limestone sitting atop bedrock known as the Florida Platform. The emergent portion of the platform was created during the Eocene to Oligocene as the Gulf Trough filled with silts, clays, and sands. Flora and fauna began appearing during the Miocene. No land animals were present in Florida ...
The exposure of limestone at the surface in the Crawford Upland results in the formation of caves, dolines, and other surface expressions of karst topography. The alternating sandstones, limestones, and shale of the West Baden and Stephensport groups that compose the Crawford Upland are Mississippian in age. [ 2 ]
The Pennyroyal Plateau or Pennyroyal Region, often spelled Pennyrile, [1] is a large physiographic region of Kentucky that features rolling hills, caves, and karst topography in general. It is named for Hedeoma pulegioides (the American pennyroyal), a wild mint that grows in the area.
