Flatside Wilderness Area
The Flatside Wilderness is a 9,507-acre protected area in the U.S. state of Arkansas. It is one of six wilderness areas in the Ouachita National Forest and also the easternmost. Outdoor enthusiasts can enjoy the area in a number of ways, including an 8.9-mile section of the Ouachita National Recreation Trail. History The Flatside Wilderness was designated by passage of "The Arkansas Wilderness Act of 1984", Public Law 98-508, which was signed by President Ronald Reagan on October 19, 1984. Senator Dale Bumpers (D-AR) sponsored the Act in the U.S. Senate, which was co-sponsored by Senator David Pryor (D-AR) and Senator John Tower (R-TX). An earlier version of the bill called "The Arkansas Wilderness Act of 1983" had been sponsored in the House of Representatives by Representative Beryl Anthony (D-AR) and Representative Ed Bethune (R-AR). On September 8, 2019, a bill sponsored by Congressman French Hill was signed into law which expanded the wilderness area by 640 acres. The a ...

Quartz
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The atoms are linked in a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at . Since the transformation is accompanied by a significant change in volume, it can easily induce microfracturing of ceramics or rocks passing through this temperature threshold. There are many different varieties of quartz, several of which are classified as gemstones. Since antiquity, varieties of quartz have been the most commonly used minerals in the making of jewelry and hardstone carvings, especially in Eurasia. Quartz is the mineral defining the val ...

Mississippian (geology)
The Mississippian ( , also known as Lower Carboniferous or Early Carboniferous) is a subperiod in the geologic timescale or a subsystem of the geologic record. It is the earlier of two subperiods of the Carboniferous period lasting from roughly 358.9 to 323.2 million years ago. As with most other geochronologic units, the rock beds that define the Mississippian are well identified, but the exact start and end dates are uncertain by a few million years. The Mississippian is so named because rocks with this age are exposed in the Mississippi Valley. The Mississippian was a period of marine transgression in the Northern Hemisphere: the sea level was so high that only the Fennoscandian Shield and the Laurentian Shield were dry land. The cratons were surrounded by extensive delta systems and lagoons, and carbonate sedimentation on the surrounding continental platforms, covered by shallow seas. In North America, where the interval consists primarily of marine limestones, it is treate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jackfork Sandstone
The Jackfork Sandstone, also referred to as the Jackfork Group, is a geologic formation associated with the Ouachita Fold and Thrust Belt exposed in western Arkansas and southeastern Oklahoma. It is named for Jackfork Mountain in Pittsburg and Pushmataha counties, Oklahoma. The Jackfork Sandstone is a thin- to massive-bedded, fine- to coarse-grained, brown, tan, or gray quartzitic sandstone with subordinate brown, silty sandstone and dark gray shale. It outcrops from Pulaski County, Arkansas in the east to Atoka County, Oklahoma in the west, a distance of over 200 miles. It is highly weather-resistant, resulting in a continuous chain of prominent ridges, including Rich Mountain, the second highest natural point in the Ouachita Mountains.

Pennsylvanian (geology)
The Pennsylvanian ( , also known as Upper Carboniferous or Late Carboniferous) is, in the International Commission on Stratigraphy, ICS geologic timescale, the younger of two period (geology), subperiods (or upper of two system (stratigraphy), subsystems) of the Carboniferous Period. It lasted from roughly . As with most other geochronology, geochronologic units, the stratum, rock beds that define the Pennsylvanian are well identified, but the exact date of the start and end are uncertain by a few hundred thousand years. The Pennsylvanian is named after the U.S. state of Pennsylvania, where the coal-productive beds of this age are widespread. The division between Pennsylvanian and Mississippian (geology), Mississippian comes from North American stratigraphy. In North America, where the early Carboniferous beds are primarily marine limestones, the Pennsylvanian was in the past treated as a full-fledged geologic period between the Mississippian and the Permian.

Bigelow, Arkansas
Bigelow is a town in Perry County, Arkansas, United States. Located in Central Arkansas near the confluence of the Fourche La Fave River and Arkansas River, the community was incorporated in 1905 as Esau. Based largely on the timber industry, the town grew until the lumber mills were closed in 1920. The population was 329 at the 2000 census. History Bigelow did not exist by its current name until 1911, as it was formerly known as "Esau"—a community a few miles southwest of the present Bridge that grew to border the edge of the small town of Fourche. In 1911, Fourche River Mill owner, N.P. Bigelow, built an elaborate white house of the best lumber on a hill above the town. He was elected mayor, and then gained permission from the state's General Assembly to change the name of Esau to Bigelow. It was at one time the biggest town in the county; a vote was taken to move the county seat from Perryville to Bigelow, Bigelow won the vote, but the move was never made. Geography Bigelow ...

Arkansas River
The Arkansas River is a major tributary of the Mississippi River. It generally flows to the east and southeast as it traverses the U.S. states of Colorado, Kansas, Oklahoma, and Arkansas. The river's source basin lies in the western United States in Colorado, specifically the Arkansas River Valley. The headwaters derive from the snowpack in the Sawatch and Mosquito mountain ranges. It flows east into the Midwest via Kansas, and finally into the South through Oklahoma and Arkansas. At , it is the sixth-longest river in the United States, the second-longest tributary in the Mississippi–Missouri system, and the 45th longest river in the world. Its origin is in the Rocky Mountains in Lake County, Colorado, near Leadville. In 1859, placer gold discovered in the Leadville area brought thousands seeking to strike it rich, but the easily recovered placer gold was quickly exhausted. The Arkansas River's mouth is at Napoleon, Arkansas, and its drainage basin covers nearly .See wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mount Magazine
Mount Magazine, officially named Magazine Mountain, is the highest point of the U.S. Interior Highlands and the U.S. state of Arkansas, and is the site of Mount Magazine State Park. It is a flat-topped mountain or mesa capped by hard rock and rimmed by precipitous cliffs. There are two summits atop the mountain: Signal Hill, which reaches , and Mossback Ridge, which reaches . Mount Magazine is often called "the highest point between the Alleghenies and the Rockies", however, there are mountains located in far west Texas, that exceed Mount Magazine in elevation and prominence. Etymology According to English botanist Thomas Nuttall, writing in 1819, French hunters named mountain "Magazine" or "Barn" (French ) because of its "peculiar form". However, today some scholars believe Nuttall may have been writing about nearby Mount Nebo, and what is today called Mount Magazine was labeled "Castete Mt" on Nuttall's maps.

Ouachita Mountains
The Ouachita Mountains (), simply referred to as the Ouachitas, are a mountain range in western Arkansas and southeastern Oklahoma. They are formed by a thick succession of highly deformed Paleozoic strata constituting the Ouachita Fold and Thrust Belt, one of the important orogenic belts of North America. The Ouachitas continue in the subsurface to the northeast, where they make a poorly understood connection with the Appalachians and to the southwest, where they join with the Marathon uplift area of West Texas. Together with the Ozark Plateaus, the Ouachitas form the U.S. Interior Highlands. The highest natural point is Mount Magazine at . The Ouachita Mountains is a Level III ecoregion designated by the Environmental Protection Agency (EPA). The region has been subdivided into six Level IV ecoregions. Etymology Louis R. Harlan claimed that "Ouachita" is composed of the Choctaw words ''ouac'' for "buffalo" and ''chito'' for "large", together meaning "country of large buffa ...
