Etonia Creek
Etonia Creek, also known as Etoniah Creek, is a stream in Putnam and Clay counties in Florida. It is the major tributary of Rice Creek, which is a tributary of the St. Johns River. The upper or western part () of the stream's basin, the Upper Etonia Creek Basin, contains about 100 lakes. Many of those lakes do not have outflowing streams. On leaving its upper basin, Etonia Creek flows eastward, and then southeastward to its juncture with Rice Creek. Upper basin The Upper Etonia Creek Basin (UECB) is a region of sand hills rising to above sea level. Small portions of the basin extend into Alachua and Bradford counties. The peaks of the hills are as much as above the lakes they adjoin. Blue Pond, in the northwest corner of the basin, is the highest of the lakes in the basin, at above sea level. Lake Grandin, at the southeast corner of the upper basin, is the lowest, at . While the surface level of some lakes is relatively stable, other lakes have had surface levels vary by ...

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 ...

North Florida
North Florida is a region of the U.S. state of Florida comprising the northernmost part of the state. Along with South Florida and Central Florida, it is one of Florida's three most common "directional" regions. It includes Jacksonville and nearby localities in Northeast Florida, an interior region known as North Central Florida, and the Florida Panhandle. Geography Area As with many vernacular regions, North Florida does not have any officially designated boundaries or status, and is defined differently in different sources. A 2007 study of Florida's regions by geographers Ary Lamme and Raymond K. Oldakowski found that Floridians surveyed identified "North Florida" as comprising the northernmost areas of the state, including both the peninsula and the Florida Panhandle. Additionally, two localized "directional" regions had emerged: North East Florida, also known as the "First Coast", representing the area around Jacksonville on the Atlantic coast, and North Central Florida, comp ...

Rivers Of Florida
This is a list of streams and rivers in the U.S. state of Florida. With one exception, the streams and rivers of Florida all originate on the Coastal plain. That exception is the Apalachicola River, which is formed by the merger of the Chattahoochee River, which originates in the Appalachian Mountains, and the Flint River, which originates in the Piedmont. Most streams and rivers in Florida start from swamps, while some originate from springs or lakes. Many of the streams and rivers are underground for part of their courses. The Everglades, sometimes called the "river of grass", is a very wide and shallow river that originates from Lake Okeechobee. Most of Florida's streams and rivers drain into the Gulf of Mexico. Drainage on the east coast of Florida is dominated by the St. Johns River, which, with the swamps that form its headwaters, extends parallel to the coast from inland of Fort Pierce to Jacksonville. By drainage basin Atlantic coast Rivers are listed as they enter the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Etoniah State Forest
Etoniah Creek State Forest is in the U.S. state of Florida. The forest is located in North Central Florida, west of Palatka near Florahome. This area is the only known site for '' Conradina etonia'', an endangered plant. Etoniah Creek forest has two tracts. The main tract runs from Coral Farms Road southwest of George's Lake toward the north side of Florida State Road 100 east of Florahome, and includes the creek of the namesake of the forest. The Manning Tract is northeast of the main tract along Putnam County Road 309D (Bardin Road), and is named for Manning Road, a local side street on the west side of that route. The Palatka-Lake Butler State Trail bisects the southern edge of the forest. The Florida National Scenic Trail also runs through parts of the forest. See also *List of Florida state forests *List of Florida state parks There are 175 state parks and 9 state trails in the U.S. state of Florida which encompass more than , providing recreational opportunities ...

Weathering
Weathering is the deterioration of rocks, soils and minerals as well as wood and artificial materials through contact with water, atmospheric gases, and biological organisms. Weathering occurs ''in situ'' (on site, with little or no movement), and so is distinct from erosion, which involves the transport of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity. Weathering processes are divided into ''physical'' and ''chemical weathering''. Physical weathering involves the breakdown of rocks and soils through the mechanical effects of heat, water, ice, or other agents. Chemical weathering involves the chemical reaction of water, atmospheric gases, and biologically produced chemicals with rocks and soils. Water is the principal agent behind both physical and chemical weathering, though atmospheric oxygen and carbon dioxide and the activities of biological organisms are also important. Chemical weathering by biological action is also known as biological wea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Bradford County, Florida
Bradford County is a county in the U.S. state of Florida. As of the 2020 census, the population was 28,303. Its county seat and largest city is Starke. History New River County, as it was known at the time, was created in 1858 from segments of Columbia and Alachua counties. It was renamed Bradford County in 1861 in honor of Confederate Captain Richard Bradford, who fought in the American Civil War and was killed in the Battle of Santa Rosa Island, becoming the first officer from Florida to die during the Civil War. During the county's early history, Lake Butler served as the county seat. However, the growth of Starke as an important city on the Fernandina to Cedar Key railroad led to an 1875 vote on the location of the county seat, with Starke winning by 46 votes. A successful legal challenge brought the county seat back to Lake Butler, and an 1885 referendum reaffirmed the move by 19 votes. Yet another referendum was held in 1887, and saw the courthouse and county seat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
