Central Tennessee’s unique geology makes sinkholes common. The area sits on soluble limestone, a key feature of karst landscapes. Groundwater dissolves these rocks, creating voids that collapse under pressure. This process shapes the landscape and affects city planning. It’s a big challenge. Studies show how land use affects geological risks. A 2009 Sinkhole-Floodplain Report looked […]
Tennessee’s Cumberland Plateau is known for its active karst system. This area has a lot of limestone, which leads to underground erosion. Perry County TN is right in the middle of this, where water and rock shape the land. There are over 120 sinkholes in Perry County, with depths from 15 to 90 feet. Digital […]
Eastern Tennessee’s landscape has a hidden story beneath its surface. The area sits on top of soluble carbonate rock layers that dissolve over time. This creates karst formations, sinkholes, caves, and underground drainage systems. Recent studies found 306 significant depressions using digital elevation mapping. There are also 695 documented subsurface voids and surface openings. These […]
Central Tennessee is home to a unique natural wonder. The area sits on Ordovician limestone, a rock layer from over 450 million years ago. This rock is soft and dissolves slowly, creating caves, springs, and sinkholes. Recent studies found 1,347 sinkholes in the area. Among them, 330 are over 3 meters deep. The U.S. Geological […]
Tennessee’s karst geology has shaped landscapes over millennia. Water dissolving limestone has created unique terrains. About 20% of the United States has similar landscapes, but Meigs County stands out. Its porous bedrock and rainfall lead to erosion. This erosion forms depressions, from small soil collapses to huge cavities. These depressions are a result of the […]
Tennessee’s karst landscapes are unique, with limestone making up 25% of the state. This limestone slowly dissolves, creating underground voids that collapse into sinkholes. This is a big issue in Loudon County, where these formations are common. Recent studies found 807 depressions in the county, with 795 being deep sinkholes. More than 40% of these […]
Central Tennessee’s unique geology makes it perfect for sinkholes. The limestone bedrock dissolves, creating karst terrain that can collapse suddenly. Studies show 239 sinkholes deeper than 10 feet, linked to underground water flow. This area is fourth in the state for sinkholes. The Cumberland Plateau’s fractured strata cause frequent changes. Over 600 depressions are mapped, […]
Madison County’s landscape has a hidden story beneath its surface. It sits on karst terrain, rich in limestone, which groundwater can dissolve over time. This leads to underground cavities that sometimes collapse, creating sinkholes. Three verified sinkholes are marked on the county’s hazard map. They are mainly near Shepherds Field and Thurston’s property. These spots […]
Central Tennessee’s karst terrain poses unique geological challenges, like in Macon County. This area is in a limestone-rich belt that’s prone to sinkholes. Over 20 years, 37 depressions have been found here, with 12 being over 3 meters deep. Advanced mapping techniques confirm these findings. LiDAR surveys and 10m DEM analysis match USGS quadrangle data. […]
