The fauna and flora of Alabama are similar to those of the Gulf states in general and have no distinctive characteristics. However, the Mobile River system has a high incidence of endemism among freshwater mollusks and biodiversity is high. In Alabama, vast forests of pine constitute the
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 ]
Newsome Sinks Karst Area: November 1973: Union Hill: Morgan: Private An area hollowed out by more than 40 caves, with over 50,000 feet (15,000 m) of known passages. Red Mountain Expressway Cut: November 1987: Birmingham
Karst is a landscape filled with limestone or other similarly soluble rocks underground. Acidic waters erode the underlying rocks over millions of years and leave an underground drainage system ...
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 ...
It is notable for its extensive karst limestone, which comprise the caves at Mammoth Cave National Park. This region includes a portion of what the U.S. Forest service calls the "Central Hardwood Forest". [2] The region extends from southern Ohio, Indiana and Illinois through Tennessee and central Kentucky and into northern Alabama.
The greatest amount of karst sinkhole damage in the United States occurs in Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania. [23] The largest recent sinkhole in the USA is possibly one that formed in 1972 in Montevallo, Alabama, as a result of man-made lowering of the water level in a nearby rock quarry. This "December ...
