Devil's Backbone State Forest
Devil's Backbone State Forest is a state forest in Shenandoah County, Virginia. It lies on the slope of North Mountain in the drainage area of Cedar Creek near Star Tannery west of Strasburg. The forest was established by a grant by John and Bernice Hoffman, who owned the land since 1950. The forest is managed by the Virginia Department of Forestry, with a focus on research relating to the re-establishment of American chestnut trees. Public access is not permitted. History Although much of future state forest was too steep and the soil too thin for agriculture, it nonetheless was part of a growing Virginia economy. The first industry to use the forest was iron furnaces established in the mid-18th century and existing until after the Civil War. Isaac Zane, a Quaker from Pennsylvania, built the first two of these furnaces (Zane's Old Furnace 1768-74 and The Marlboro Works 1772-95) and received grants of forest land which included the future state forest to be used to make c ...

Shenandoah County, Virginia
Shenandoah County (formerly Dunmore County) is a county located in the Commonwealth of Virginia. As of the 2020 United States Census, the population was 44,186. Its county seat is Woodstock. It is part of the Shenandoah Valley region of Virginia. History The Senedos, possibly an Iroquoian group, are thought to have occupied the area at one time, until they were said to have been slaughtered by the Catawba in the latter 17th century. The name of the Valley, and of the County, is most likely connected with this Native American group. It has also been attributed to General George Washington naming it in honor of John Skenandoa, an Oneida chief from New York who helped gain support of Oneida and Tuscarora warriors to aid the rebel colonists during the American Revolutionary War. Colonial Governor Gooch formally purchased the entire Shenandoah Valley from the Six Nations of the Iroquois by the Treaty of Lancaster in 1744. The Iroquois had controlled the valley as a hunting gr ... [...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 lime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Protected Areas Of Shenandoah County, Virginia
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 servin ...

Virginia State Forests
Virginia, officially the Commonwealth of Virginia, is a state in the Mid-Atlantic and Southeastern regions of the United States, between the Atlantic Coast and the Appalachian Mountains. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna. The capital of the Commonwealth is Richmond; Virginia Beach is the most-populous city, and Fairfax County is the most-populous political subdivision. The Commonwealth's population was over 8.65million, with 36% of them living in the Baltimore–Washington metropolitan area. The area's history begins with several indigenous groups, including the Powhatan. In 1607, the London Company established the Colony of Virginia as the first permanent English colony in the New World. Virginia's state nickname, the Old Dominion, is a reference to this status. Slave labor and land acquired from displaced native tribes fueled the growing pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Virginia State Forests
The Virginia state forest system includes 26 state-managed forests covering a total of . They are managed by the Virginia Department of Forestry. The system was created to manage and maintain forests for wildlife, timber production, recreation, water quality, and aesthetics. The system receives no taxpayer funds, and is self-supported by the sale of forest products. Most Virginia state forests are accessible to the public. Activities such as hiking, biking, horseback riding, hunting, and fishing are permitted in some state forests; permissible uses vary between individual state forests. Some activities require the purchase of a "State Forest Use Permit" for individuals ages 16 or older.

Chestnut Blight
The pathogenic fungus ''Cryphonectria parasitica'' (formerly ''Endothia parasitica'') is a member of the Ascomycota (sac fungi). This necrotrophic fungus is native to East Asia and South East Asia and was introduced into Europe and North America in the early 1900s. The fungus spread rapidly and caused significant tree loss in both regions. Overview ''Cryphonectria parasitica'' is a parasitic fungus of chestnut trees. This disease came to be known as chestnut blight. Naturally found in South East Asia, accidental introductions led to invasive populations of ''C. parasitica'' in North America and Europe. The fungal disease has had a devastating economic and social impact on communities in the eastern United States. In the first half of the 20th century it killed an estimated four billion trees; or, by another count, 3.5 billion trees through 2013. Less severe impacts have occurred in Europe due to widespread CHV1-induced ''hypovirulence''. CHV1 is one of at least two viral pathog ...

Appalachian Mountains
The Appalachian Mountains, often called the Appalachians, (french: Appalaches), are a system of mountains in eastern to northeastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion. The Appalachian chain is a barrier to east–west travel, as it forms a series of Ridge-and-Valley Appalachians, alternating ridgelines and valleys oriented in opposition to most highways and railroads running east–west. Definitions vary on the precise boundaries of the Appalachians. The United States Geological Survey (USGS) defines the ''Appalachian Highlands'' Physiographic regions of the world, physiographic division as consisting of 13 provinces: the Atlantic Coast Uplands, Eastern Newfoundland Atlantic, Maritime Acadian Highlands, Maritime Plain, Notre Dame and Mégantic Mountains, Western Newfoundland Mountains, Pied ...

Loblolly Pine
''Pinus taeda'', commonly known as loblolly pine, is one of several pines native to the Southeastern United States, from East Texas to Florida, and north to southern New Jersey. The wood industry classifies the species as a southern yellow pine. U.S. Forest Service surveys found that loblolly pine is the second-most common species of tree in the United States, after red maple. For its timber, the pine species is regarded as the most commercially important tree in the Southeastern U.S. The common name loblolly is given because the pine species is found mostly in lowlands and swampy areas. Loblolly pine is the first among over 100 species of ''Pinus'' to have its complete genome sequenced. As of March 2014, it was the organism having the largest sequenced genome size. Its genome, with 22 billion base pairs, is seven times larger than that of humans. As of 2018, assembly of the axolotl genome (32Gb) displaced loblolly pine as the largest assembled genome. The loblolly pine was sele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shenandoah Valley

Quicklime
Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term "'' lime''" connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate. By contrast, ''quicklime'' specifically applies to the single chemical compound calcium oxide. Calcium oxide that survives processing without reacting in building products such as cement is called free lime. Quicklime is relatively inexpensive. Both it and a chemical derivative ( calcium hydroxide, of which quicklime is the base anhydride) are important commodity chemicals. Preparation Calcium oxide is usually made by the thermal decomposition of materials, such as limestone or seashells, that contain calcium carbonate (CaCO3; mineral calcite) in a lime kiln. This is accomplished by heating the material to above ,Merc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
