Big Spring (Missouri)
__NOTOC__ Big Spring is one of the largest springs in the United States and the world.Vineyard and Federer, 1982, p. 12 An enormous first magnitude spring, it rises at the base of a bluff on the west side of the Current River valley in the Missouri Ozarks. Location Located about four miles downstream from Van Buren, it is within the boundaries of the Ozark National Scenic Riverways, and its visitor facilities are managed by the National Park Service. It is a contributing resource to Big Spring Historic District, listed on the National Register of Historic Places in 1981. Description The average flow of of water per second from Big Spring constitutes the second largest tributary of the Current River. The spring is by far the largest spring in the Ozark Plateau region. The only two springs in the Ozark region that approach the size of Big Spring are Greer Spring and Mammoth Spring. Maximum discharge of Big Spring must be estimated because backwater from the Current Rive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo-Americ ...

Mammoth Spring
Mammoth Spring is a large, Spring (hydrology), first magnitude karst spring that arises in the Ozark Plateau within the state of Arkansas. It is the largest spring in Arkansas and the third-largest spring within the Ozark Plateau region behind Big Spring (Missouri), Big Spring and Greer Spring (Missouri), Greer Spring. Mammoth Spring is the seventh-largest natural spring in the world. The spring's outlet pool is contained entirely within Mammoth Spring State Park. The park is located in the town of Mammoth Spring, Arkansas, Mammoth Spring, which lies in extreme north-central Arkansas. The outlet pool is adjacent to U.S. Route 63 in Arkansas, US Highway 63, only 500 ft. south of the Missouri border, and it can be readily seen from the highway. The spring's large discharge volume rushes a few hundred feet down the outlet channel before merging with the Warm Fork Spring River, Warm Fork of the Spring River to form the Spring River (Arkansas), Spring River.

Protected Areas Of The U
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servi ...

Karst Spring
A karst spring or karstic spring is a spring (outflow of groundwater) that is part of a karst hydrological system. Description Because of their often conical or inverted bowl shape, karst springs are also known in German-speaking lands as a ''Topf'' ("pot") which is reflected in names such as Aachtopf (the source of the Radolfzeller Aach) or Blautopf (the source of the Blau river in Blaubeuren). Karst springs often have a very high yield or discharge rate, because they are often fed by underground drainage from a large catchment basin. Because the springs are usually the terminus of a cave drainage system at the place where a river cave reaches the Earth's surface, it is often possible to enter the caves from karst springs for exploration. Large karst springs are located in many parts of the world; the largest ones are believed to be in Papua New Guinea, with others located in Mediterranean countries such as Bosnia and Herzegovina, Croatia, Turkey, Slovenia, and Italy.

List Of Ozark Springs
This is a list of natural springs in the Ozark Plateau ordered by spring magnitude. Different sources may give differing values for average daily flow of the same spring. This can result from different measuring methodologies and from a varying number of observations over different timespans. The sources for the flow data presented here are cited in the footnotes. The majority of these springs have been measured less than 10 times, at random intervals. The exceptions are Big Spring, Greer Spring, Mammoth Spring, Bennett Spring, Maramec Spring, Alley Spring, and Round Spring, which have all been measured for more than 3 years on a daily basis by the United States Geological Survey (USGS). List Some sources give million gallons per day, which is equivalent to 1.547229 ft3/s. Some second magnitude springs could be considered first magnitude, and ''vice versa'', depending on the data used. This list includes only some of the larger second order springs, and the number of third m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cave
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorgani ...

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 19th century, which entered German much earlier ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eleven Point River
The Eleven Point River is a river in southern Missouri and northern Arkansas, United States. It originates near Willow Springs, Missouri. It more than doubles in flow when Greer Spring Branch runs into it, adding over of water per day to the river. The name derives from the Mississippi Valley French word ''pointe'', which is a wooded point of land marking a river bend. ''Voyageurs'' marked distance by counting these points of land or river bends. The river flows into the Spring River southwest of Pocahontas near the small town of Black Rock. In 1968 a stretch was named the Eleven Point National Wild and Scenic River, one of the original eight rivers chosen to be part of the United States National Wild and Scenic Rivers System.

Greer Spring (Missouri)
Greer Spring is a first magnitude spring located in the southeast portion of the Ozark Plateau, in Oregon County in south-central Missouri within the boundaries of the Mark Twain National Forest. The spring is the second largest spring in the Ozarks, with an average discharge of of water per second. Greer Spring was designated a National Natural Landmark in 1980. The spring outlet The spring emerges at the bottom of a narrow chasm. An upper outlet flowing from a cavern is only a fraction of Greer Spring's large flow. About downstream (north) the main outlet boils to the surface in a mixture of deep, aqua-blue water, moss covered rocks, and frothy whitewater. The newly formed surface stream then races down a small, steep, hardwood blanketed gorge dropping in elevation for to its confluence with the Eleven Point River. Greer Spring greatly increases the flow of the river, ensuring ample water for recreational activities, such as boating, even in the dry months. The vast amo ...
