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 valley is notable for its karst formations, which have been designated a National Natural Landmark. Grassy Cove is also home to a small unincorporated community . Grassy Cove is located atop the Cumberland Plateau , approximately 5 miles (8.0 km) east of Crossville and 5 miles (8.0 km) west of the plateau's Walden Ridge escarpment.
Karst springs - springs that often carry cave water. [29] Karst windows - small section of a underground river that is exposed to the surface. [30] Limestone - Calcium carbonate based sedimentary rock that often forms caves. [31] Losing streams - a common feature of karst areas. [32] Sinkholes - collapse features that often form cave entrances ...
The Indiana Karst Conservancy is working to raise more awareness of the state’s unique karst landscapes. Trash and other materials get dumped into sinkholes and pits, leading to pollution ...
A Laodracon carsticola, or Khammouan karst dragon, perched on a rock. The new species has so far only been found in one karst formation in Khammouane Province, the study said.
The geology of Tennessee is as diverse as its landscapes. Politically, Tennessee is broken up into three Grand Divisions : East , Middle , and West Tennessee . [ 1 ] Physically, Tennessee is also separated into three main types of landforms: river valley plain, highlands and basins, and mountains.
The local Facebook group HVL Rocks has members painting and hiding rocks. They have been found all across the U.S. and even overseas.
Rock of the Knox group in the central uplift are raised 250 m (820 ft) above their normal position and locally contain shatter cones. In the rim surrounding the crater, Ordovician limestone has been uplifted 10–50 m (33–164 ft) and is moderately to tightly folded into doubly plunging anticlines and synclines that have axes concentric to the ...
