Mixed- federal, state, & private The second largest river delta in the US, this 260,000-acre (1,100 km 2) site has a wide range of habitats and wildlife. The 200-mile (320 km) Bartam Canoe Trail goes through the delta. Newsome Sinks Karst Area: November 1973: Union Hill
The valley was named for William Newsome who settled in the area in 1838. It is approximately 4 miles (6.4 km) long and up to .75 miles (1.21 km) wide. The NNL covers 1,700 acres (690 ha), but the total karst area is around 9,925 acres (4,017 ha). [2]
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 ]
Oak-hickory woodland is the most common natural community in the Interior Low Plateaus. It is the dominant natural community for many areas of rolling hills, including the Western Highland Rim, Shawnee Hills, and Outer Bluegrass. These woodlands represent an intermediate state between a forest and a savanna. [citation needed]
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 ...

Glaciokarst is a geological term that refers to a specific type of karst landscape that has been influenced significantly by past glacial activity. [1] Karst landscapes consist of distinctive surface and subsurface landforms. These landforms are a result of the dissolution of soluble rocks like limestone, gypsum or dolomite by water. [2]
