Central Kentucky is known for its unique geology. It sits on a karst landscape made of soluble limestone. Over thousands of years, groundwater has slowly dissolved this rock, creating underground voids and channels. This process of dissolution sinkhole formation happens when surface water seeps into the soil. It then flows into fractures below. Chemical reactions […]
Central Kentucky’s landscape is home to a vast network of underground caves and waterways. These are shaped by soluble limestone bedrock. Over 45% of the state sits atop karst formations, created by water dissolving rock over thousands of years. Jefferson County is in a high-risk zone, where sinkholes often appear due to shifting terrain. There […]
Jackson County in Kentucky is known for its unique karst terrain. This area has been shaped by thousands of years of geological changes. The ground is made of soluble limestone, a key feature of karst systems that cover over 40% of the state. Water slowly breaks down these rocks, creating underground voids. These voids eventually […]
Kentucky’s landscape is full of hidden karst formations. These are areas where water dissolves rock like limestone. The Kentucky Geological Survey says over 40% of the state has karst areas. Lincoln County is in the Western Pennyroyal region. This area is known worldwide for its sinkholes and underground water systems. These sinkholes form over time […]
Kentucky’s landscape has a hidden story beneath its surface. The state sits on a karst terrain, shaped by water dissolving limestone over millennia. This creates underground systems, caves, and sinkholes, common in areas like the Western Pennyroyal. The Western Pennyroyal region, where Henry County is, has lots of limestone. Rainwater mixes with carbon dioxide to […]
Western Kentucky’s unique geology creates natural hazards that shape land and communities. Beneath Grayson County lies ancient Mississippian-era limestone bedrock. This rock is prone to karst terrain and dissolves over time. This dissolution creates underground voids that collapse into sinkholes. According to Kentucky Geological Survey research, 83% of the county’s surface sits atop this porous […]
Hardin County in Kentucky is located in a region known for its fragile ground. The area’s landscape is shaped by limestone, which is easily dissolved by water. This has led to the formation of 6,936 documented sinkholes across the Mississippian Plateaus. The elevation in Hardin County varies from 383 to 1,017 feet. This creates a […]
Kentucky’s landscape is full of hidden underground systems. These systems were shaped by ancient forces. In places like Harlan County, the ground is made of limestone that water can dissolve. Over time, this water creates underground tunnels and holes. These holes can collapse, forming sinkholes. The Kentucky Geological Survey says this is key to understanding […]
Western Kentucky’s unique geology shapes its landscape in Hancock County. The area sits on the Pennyroyal Plateau, a karst terrain with soluble limestone bedrock. Over time, groundwater has dissolved these rocks, creating underground cavities that sometimes collapse into sinkholes. The Kentucky Geological Survey has documented four sinkholes in Hancock County. They were mapped through field […]
