Skyline Caverns
Skyline Caverns is a series of geologic caves and a tourist attraction located in Warren County, Virginia, south of Front Royal, Virginia, Front Royal. The caverns were discovered by Walter S. Amos, a retired geologist and mineralogist from Winchester, Virginia, on December 17, 1937. Skyline Caverns is open year-round, offering guided tours through the caverns. History Walter S. Amos was contracted by several private and government agencies to search for caves and caverns to open in conjunction with Skyline Drive. During his search, he came across a sinkhole that was located approximately where the parking lot is currently situated. Normally, sinkholes are created by the collapsing of a cavern roof, which takes the ground above with it. When he saw there was no water in the sinkhole, which meant there had to be a drain nearby, he believed he had discovered a cavern. Knowing this, Amos began to search the edges for some opening to the possible cave system below. He found this ope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warren County, Virginia
Warren County is a U.S. county located in the Commonwealth of Virginia. The 2020 census places Warren County within the Washington-Arlington-Alexandria, DC-VA-MD-WV Metropolitan Statistical Area with a population of 40,727. The county seat is Front Royal. History By 1672 the entire Shenandoah Valley was claimed for hunting by the Iroquois Confederation following the Beaver Wars. Some bands of the Shawnee settled in the area as client groups to the Iroquois and alternately to the Cherokee after 1721. The Iroquois formally sold their entire claim east of the Alleghenies to the Virginia Colony at the Treaty of Lancaster in 1744. Warren County was established in 1836 from Frederick and Shenandoah counties. At that time the county had a population of 7,000 people, a quarter of which were enslaved. Wedding records show marriages of people born in the 1770s marrying in the 1800s who head households of four to eight "free colored" so the early demographics of the population are uncl ...

Anthodite
Anthodites (Greek ἄνθος ''ánthos'', "flower", ''-ode'', adjectival combining form, ''-ite'' adjectival suffix) are speleothems (cave formations) composed of long needle-like crystals situated in clusters which radiate outward from a common base. The "needles" may be quill-like or feathery. Most anthodites are made of the mineral aragonite (a variety of calcium carbonate, CaCO3), although some are composed of gypsum (CaSO4·2H2O). The term ''anthodite'' is first cited in the scientific literature in 1965 by Japanese researcher N. Kashima, who described "flower-like dripstone" composed of "an alternation of calcite and aragonite". Structure, composition and appearance The individual crystals of anthodites develop in a form described as "acicular" (needle-like) and often branch out as they grow. They usually grow downward from a cave's ceiling. Aragonite crystals are contrasted with those made of calcite (another variety of calcium carbonate) in that the latter tend to be s ...

Landmarks In Virginia
A landmark is a recognizable natural or artificial feature used for navigation, a feature that stands out from its near environment and is often visible from long distances. In modern use, the term can also be applied to smaller structures or features, that have become local or national symbols. Etymology In old English the word ''landmearc'' (from ''land'' + ''mearc'' (mark)) was used to describe a boundary marker, an "object set up to mark the boundaries of a kingdom, estate, etc.". Starting from approx. 1560, this understanding of landmark was replaced by a more general one. A landmark became a "conspicuous object in a landscape". A ''landmark'' literally meant a geographic feature used by explorers and others to find their way back or through an area. For example, the Table Mountain near Cape Town, South Africa is used as the landmark to help sailors to navigate around southern tip of Africa during the Age of Exploration. Artificial structures are also sometimes built to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Limestone Caves
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 limestone co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caves Of Virginia
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 ...

Speleothems
A speleothem (; ) is a geological formation by mineral deposition (geology), deposits that accumulate over time in natural caves. Speleothems most commonly form in calcareous caves due to carbonate dissolution reactions. They can take a variety of forms, depending on their depositional history and environment. Their chemical composition, gradual growth, and preservation in caves make them useful paleoclimatology, paleoclimatic proxies. Chemical and physical characteristics More than 300 variations of cave mineral deposits have been identified. The vast majority of speleothems are calcareous, composed of calcium carbonate (CaCO3) minerals (calcite or aragonite). Less commonly, speleothems are made of calcium sulfate (gypsum or mirabilite) or opal. Speleothems of pure calcium carbonate or calcium sulfate are translucent and colorless. The presence of iron oxide or copper provides a reddish brown color. The presence of manganese oxide can create darker colors such as black or dark b ...

Cave Cricket
The orthopteran family Rhaphidophoridae of the suborder Ensifera has a worldwide distribution. Common names for these insects include cave wētā, cave crickets, camelback crickets, camel crickets, Hogan bugs, spider crickets (sometimes shortened to "criders", or "land shrimp" or "sprickets",) and sand treaders. Those occurring in New Zealand, Australia, and Tasmania are typically referred to as jumping or cave wētā. Most are found in forest environments or within caves, animal burrows, cellars, under stones, or in wood or similar environments. All species are flightless and nocturnal, usually with long antennae and legs. More than 500 species of Rhaphidophoridae are described. The well-known field crickets are from a different superfamily (Grylloidea) and only look vaguely similar, while members of the family Tettigoniidae may look superficially similar in body form. Description Most cave crickets have very large hind legs with "drumstick-shaped" femora and equally long, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Front Royal, Virginia
Front Royal is the only incorporated town in Warren County, Virginia, United States. The population was 15,011 at the 2020 census. It is the county seat of Warren County. History The entire Shenandoah Valley including the area to become Front Royal was annexed and claimed for hunting by the Iroquois Confederation during the later Beaver Wars, by 1672. Some bands of the Shawnee settled in the area as client groups to the Iroquois and alternately to the Cherokee after 1721. The Iroquois formally sold their entire claim east of the Alleghenies to the Virginia Colony at the Treaty of Lancaster in 1744. Front Royal, originally settled in 1754 under the name LeHewtown, had been known to European explorers as early as the 1670s, and the nearby settlement of Chester's Ferry was in existence by 1736. The town also had a well-known nickname by the 1790s, "Helltown," due to the many livestock wranglers and boatmen on the Shenandoah coming through the area, who came into town looking ...

Sinkhole
A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. The term is sometimes used to refer to doline, enclosed depressions that are locally also known as ''vrtače'' and shakeholes, and to openings where surface water enters into underground passages known as ''ponor'', swallow hole or swallet. A ''cenote'' is a type of sinkhole that exposes groundwater underneath. A ''sink'' or ''stream sink'' are more general terms for sites that drain surface water, possibly by infiltration into sediment or crumbled rock. Most sinkholes are caused by karst processes – the chemical dissolution of carbonate rocks, collapse or suffosion processes. Sinkholes are usually circular and vary in size from tens to hundreds of meters both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. Sinkholes may form gradually or suddenly, and are found worldwide. Formation Natural processes Sinkholes may capture surf ...

Skyline Drive
Skyline Drive is a National Parkway that runs the entire length of the National Park Service's Shenandoah National Park in the Blue Ridge Mountains of Virginia, generally along the ridge of the mountains. The drive's northern terminus is at an intersection with U.S. Route 340 (US 340) near Front Royal, and the southern terminus is at an interchange with US 250 near Interstate 64 (I-64) in Rockfish Gap, where the road continues south as the Blue Ridge Parkway. The road has intermediate interchanges with US 211 in Thornton Gap and US 33 in Swift Run Gap. Skyline Drive is part of Virginia State Route 48, which also includes the Virginia portion of the Blue Ridge Parkway, but this designation is not signed. A park entrance fee is charged at the four access points to the drive. Skyline Drive is a two-lane road that has 75 overlooks providing views of the Shenandoah Valley to the west and the Piedmont to the east. The drive provides access t ...
