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 ...
Barton Springs is the main discharge point for the Barton Springs segment of the Edwards Aquifer of Texas, a well known karst aquifer. Geologically, the aquifer is composed of limestone from the Cretaceous period, about 100 million years old. Fractures, fissures, conduits, and caves have developed in this limestone.
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 ]
The Texas Hill Country is a geographic region of Central and South Texas, forming the southeast part of the Edwards Plateau. Given its location, climate, terrain, and vegetation, the Hill Country can be considered the border between the American South and Southwest . [ 1 ]
A polje, also called karst polje or karst field, [1] [2] [3] is a large flat plain found in karstic geological regions of the world, with areas usually in the range of 5–400 km 2 (2–154 sq mi). The name derives from the Slavic languages , [ 4 ] [ 5 ] where polje literally means 'field', whereas in English polje specifically refers to a ...

The United States' National Historic Landmark (NHL) program is operated under the auspices of the National Park Service , and recognizes structures, districts, objects, and similar resources according to a list of criteria of ...
A karst window, also known as a karst fenster, is a geomorphic feature found in karst landscapes where an underground river is visible from the surface within a sinkhole. [ 1 ] [ 2 ] In this feature, a spring emerges, then the discharge abruptly disappears into a sinkhole .
Inner Space Cavern (Also known as Laubach Cave) is a karst cave located in Georgetown, Texas. The cavern was formed by water passing through Edwards limestone . The cavern is estimated to be around 20–25 million years old but were only open to the surface since the late Pleistocene period 14,000–45,000 years ago.
