Botetourt County, Virginia
Botetourt County ( ) is a US county that lies in the Roanoke Region of the Commonwealth of Virginia. Located in the mountainous portion of the state, the county is bordered by two major ranges, the Blue Ridge Mountains and the Appalachian Mountains. Botetourt County was created in 1770 from part of Augusta County and was named for Norborne Berkeley, known as Lord Botetourt. It originally comprised a vast area, which included the southern portion of present-day West Virginia and all of Kentucky. Portions were set off to form new counties beginning in 1772, until the current borders were established in 1851. Botetourt County is part of the Roanoke Virginia Metropolitan Statistical Area, and the county seat is the town of Fincastle. As of the 2020 census, the county population was 33,596. History First proposed in the House of Burgesses in 1767, Botetourt County was created in 1770 from Augusta County. The county is named for Norborne Berkeley, Baron de Botetourt, more c ...

Martinsburg Formation
The Ordovician Martinsburg Formation (Om) is a mapped bedrock unit in Pennsylvania, New Jersey, Maryland, Virginia, and West Virginia. It is named for the town of Martinsburg, West Virginia for which it was first described. It is the dominant rock formation of the Great Appalachian Valley in New Jersey (where it is called Kittatinny Valley and Pennsylvania (in the Lehigh Valley and Lebanon Valley). Description The Martinsburg is defined as a gray to dark gray, and infrequently tan and purple shale and slate. Local members of impure sandstone; thin, argillaceous limestone or phyllite, phyllitic shale are present in the Cumberland Valley and the Lehigh Valley.Berg, T.M., Edmunds, W.E., Geyer, A.R. and others, compilers, (1980).

Southwest Virginia
Southwest Virginia, often abbreviated as SWVA, is a mountainous region of Virginia in the westernmost part of the commonwealth. Located within the broader region of western Virginia, Southwest Virginia has been defined alternatively as all Virginia counties on the Appalachian Plateau, all Virginia counties west of the Eastern Continental Divide, or at its greatest expanse, as far east as Blacksburg and Roanoke. Another geographic categorization of the region places it as those counties within the Tennessee River watershed. Regardless of how borders are drawn, Southwest Virginia differs from the rest of the commonwealth in that its culture is more closely associated with Appalachia than the other regions of Virginia. Historically, the region has been and remains a rural area, but in the 20th century, coal mining became an important part of its economy. With the decline in the number of coal jobs and the decline of tobacco as a cash crop, Southwest Virginia is increasingly tu ...

Roadless Area Conservation
Roadless area conservation is a conservation policy limiting road construction and the resulting environmental impact on designated areas of public land. In the United States, roadless area conservation has centered on U.S. Forest Service areas known as inventoried roadless areas. The most significant effort to support the conservation of these efforts was the Forest Service 2001 Roadless Area Conservation Rule (Roadless Rule). Concept Access roads provide convenient access for industry as well as for a variety of recreational activities, such as sightseeing, fishing, hunting, and off-roading. However, these activities can cause erosion, pollution, species loss, and loss of aesthetic appeal. In addition, the building of roads can lead to further development of "splinter roads" that take off from them, and the encroachment of human settlement and development in sensitive areas. In the United States, about 30%, of National Forest lands in 38 states and Puerto Rico are roadless a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inventoried Roadless Area
Inventoried Roadless Areas are a group of United States Forest Service lands that have been identified by government reviews as lands without existing roads that could be suitable for roadless area conservation as wilderness or other non-standard protections. The Inventoried Roadless areas include approximately of land in 40 states and Puerto Rico. Most of these lands are in the western portion of the lower 48 states and Alaska.Maps of inventoried roadless areasUS Forest Service Maps Idaho alone contains over of inventoried roadless areas. The inventoried roadless areas range from large areas with wilderness characteristics to small tracts of land that are immediately adjacent to wilderness areas, parks and other protected lands. Roadless Area Review and Evaluations (RARE) The first review of Forest Service roadless lands was started in 1967 after the creation of the Wilderness Act by Congress in 1964. This effort was called the “Roadless Area Review and Evaluation” or “ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Obsidian
Obsidian () is a naturally occurring volcanic glass formed when lava extrusive rock, extruded from a volcano cools rapidly with minimal crystal growth. It is an igneous rock. Obsidian is produced from felsic lava, rich in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium. It is commonly found within the margins of rhyolite, rhyolitic lava flows known as obsidian flows. These flows have a high content of silicon dioxide, silica, granting them a high viscosity. The high viscosity inhibits atomic diffusion, diffusion of atoms through the lava, which inhibits the first step (nucleation) in the formation of mineral crystals. Together with rapid cooling, this results in a natural glass forming from the lava. Obsidian is hard, Brittleness, brittle, and amorphous; it therefore Fracture (mineralogy)#Conchoidal fracture, fractures with sharp edges. In the past, it was used to manufacture cutting and piercing tools, and it has been used experimentally as surgic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Roaring Run Furnace 3
A roar is a type of animal vocalization that is deep and resonating. Many mammals have evolved to produce roars and other roar-like vocals for purposes such as long-distance communication and intimidation. These include various species of big cats, bears, pinnipeds, bovids, deer, elephants and simians. The anatomical basis for the ability to roar often involves modifications to the larynx and hyoid bone and enlarged internal air spaces for low-frequency vocal resonation. While roaring, animals may stretch out their necks and elevate their heads to increase the space for resonance. Definition The definition of "roar" has varied between species. However Weissengruber et al. (2002) have given a more general description of roars as consisting of both a low pitch and low formant. They have used the roars of lions and red deer as quintessential examples of the sound. Other researchers have mentioned similar "roar-like" vocalizations in which either the pitch or format is still higher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brallier Formation
The Devonian Brallier Formation is a mapped bedrock unit in Pennsylvania, Maryland, West Virginia, and Virginia. Description The Brallier Formation was described by Charles Butts in 1918 as a fine-grained, siliceous shale with few fine-grained sandstone layers, from outcrops in central Pennsylvania. Others expanded usage of the term to rocks in other states. Stratigraphy The Brallier is roughly equivalent to the Scherr Formation. The contact with the underlying Harrell Formation is generally gradational. Fossils Hasson and Dennison reported the following fossils from outcrops of the lower Brallier at Keyser, West Virginia, Ridgeville, West Virginia, and McCoole, Maryland:Hasson, Kenneth O., and Dennison, John M., 1978, STRATIGRAPHY OF THE DEVONIAN HARRELL AND MILLBORO SHALES IN PARTS OF PENNSYLVANIA, MARYLAND, WEST VIRGINIA, AND VIRGINIA, Project Final Report for Energy Research and Development Administration Contract #EY-77-C-21-8153, May 197/ref> *Bivalvia: ''Buchiola retro ...

George Washington And Jefferson National Forests
The George Washington and Jefferson National Forests is an administrative entity combining two U.S. National Forests into one of the largest areas of public land in the Eastern United States. The forests cover of land in the Appalachian Mountains of Virginia, West Virginia, and Kentucky. Approximately of the forest are remote and undeveloped and have been designated as wilderness areas, which prohibits future development. History George Washington National Forest was established on May 16, 1918, as the Shenandoah National Forest. The forest was renamed after the first President on June 28, 1932. Natural Bridge National Forest was added on July 22, 1933. Jefferson National Forest was formed on April 21, 1936, by combining portions of the Unaka and George Washington National Forests with other land. In 1995, the George Washington and Jefferson National Forests were administratively combined. The border between the two forests roughly follows the James River. The combine ...
