Karst Map of the Conterminous United States - 2020
Sep 29, 2020 · Karst areas are characterized by distinctive landforms (like springs, caves, sinkholes) and a unique hydrogeology that results in aquifers that are highly productive but extremely vulnerable to contamination.

Nov 15, 2024 · karst, terrain usually characterized by barren, rocky ground, caves, sinkholes, underground rivers, and the absence of surface streams and lakes. It results from the excavating effects of underground water on massive soluble limestone.
Karst - Wikipedia
A karst fenster (karst window) occurs when an underground stream emerges onto the surface between layers of rock, cascades some distance, and then disappears back down, often into a sinkhole. Rivers in karst areas may disappear underground a number of times and spring up again in different places, even under a different name, like Ljubljanica ...

Karst, Kentucky Geological Survey, University of Kentucky
Jan 5, 2023 · The geologic hazards associated with karst are: sinkhole flooding, groundwater vulnerability, radon, and cover-collapse sinkholes described on this page. What Is a Cover-Collapse Sinkhole? Cover-collapse sinkholes occur in the soil or other loose material overlying soluble bedrock.
Karst Landscapes - Caves and Karst (U.S. National Park Service)
Karst is a type of landscape where the dissolving of the bedrock has created sinkholes, sinking streams, caves, springs, and other characteristic features. Karst is associated with soluble rock types such as limestone, marble, and gypsum.
Sinkholes - National Cave and Karst Research Institute - NCKRI
Sinkholes are the most recognized surface landform in karst. In many parts of the world, they are called “dolines.” They are depressions in the Earth and form by two primary processes: dissolution and collapse. The most common type of sinkhole is the solution sinkhole.
Karst topography: Formation, processes, characteristics, landforms ...
Jan 1, 2024 · Karst refers to any topography or landform that forms over soluble rocks. The classic karst landforms, which include enclosed depressions, sinking streams, and caves, are primarily generated by surface and subsurface waters dissolving rocks; mechanical erosion plays a secondary role.
Sinkholes in the Karst Regions: Unmasking the Fragile Landscape
Jun 5, 2024 · Sinkholes are most prevalent in areas with a type of bedrock known as karst terrain. Karst landscapes are shaped when mildly acidic water dissolves soluble rocks, mainly limestone, dolomite, and gypsum.
