Pignut Mountain
Pignut Mountain is a mountain in Rappahannock County, Virginia. It is part of the Blue Ridge Mountains. Its summit lies within Shenandoah National Park. Geology Geologically speaking, the mountain is situated in the northern subprovince of the Blue Ridge Province of the Appalachian Highlands. It is part of the Crystalline Appalachians. Pignut Mountain is separated from the main Blue Ridge by a low gap. The gap is the result of relatively rapid erosion along a geological fault. Visiting Pignut Mountain As of 2010, Pignut Mountain is entirely undeveloped and there are no trails or roads leading up the mountain. The summit can be reached by bushwhacking from the Hull School Trail, accessible from Skyline Drive. The closest scenic viewpoints along Skyline Drive from which to view Pignut Mountain are Thornton Hollow Overlook, situated on nearby Neighbor Mountain Neighbor Mountain is a mountain in Page and Rappahannock Counties, Virginia, near the city of Luray.

Rappahannock County, Virginia
Rappahannock County is a county located in the northern Piedmont region of the Commonwealth of Virginia, US, adjacent to Shenandoah National Park. As of the 2020 Census, the population was 7,348. Its county seat is Washington. The name "Rappahannock" comes from the Algonquian word ''lappihanne'' (also noted as ''toppehannock''), meaning "river of quick, rising water" or "where the tide ebbs and flows." The county is included in the Washington-Arlington-Alexandria, DC-VA-MD-WV Metropolitan Statistical Area. History Rappahannock County was founded by an act of the Virginia General Assembly in 1833, based on the growing population's need to have better access to a county seat. The county's land was carved from Culpeper County. Rappahannock County was named for the river that separates it from Fauquier County. The land on which Rappahannock County is sited was owned in the early 1700s by Thomas Fairfax 6th Lord Fairfax. It was part of the Northern Neck Proprietary, which consiste ...

Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 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, Piedmont, Blue Ridge, Valley and Ridge, St. Lawrence Valley, Appalac ...

Mountains Of Virginia
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Neighbor Mountain
Neighbor Mountain is a mountain in Page and Rappahannock Counties, Virginia, near the city of Luray. It is part of the Blue Ridge Mountains. Its summit lies in Page County, within Shenandoah National Park. Geology Geologically speaking, the mountain is situated in the northern subprovince of the Blue Ridge Province of the Appalachian Highlands. It is part of the Crystalline Appalachians. Neighbor Mountain is separated from parallel Knob Mountain to the west by a stream known as Jeremy's Run. Political Boundaries The crest of the northern arm of Neighbor Mountain forms part of the border between Page and Rappahanock Counties. Page County is located to the west of the ridge, whereas Rappahannock County is to the east. As the mountain curves south-west, the county border follows the topographical spine of the Blue Ridge from Neighbor Mountain onto Pass Mountain to the south, and the south-western arm lies entirely within Page County. On this south-western arm are a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Trail Blazing
Trail blazing or way marking is the practice of marking paths in outdoor recreational areas with signs or markings that follow each other at certain, though not necessarily exactly defined, distances and mark the direction of the trail. A blaze in the beginning meant "a mark made on a tree by slashing the bark" (''The Canadian Oxford Dictionary''). Originally a waymark was "any conspicuous object which serves as a guide to travellers; a landmark" (''Oxford English Dictionary''). There are several ways of marking trails, including paint, carvings, affixed markers, posts, flagging, cairns, and crosses, with paint being the most widely used. Types of signage Paint A painted marking of a consistent shape or shapes (often rectangular), dimension and colour or combination of colours is used along the trail route. The system by which blazes are used to signify turns and endpoints in trails (see below) strongly favors the use of paint blazes. European countries usually use systems ...

Fault (geology)
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...

Gap (landform)
A gap is a geological formation that is a low point or opening between hills or mountains or in a ridge or mountain range. It may be called a col, notch, mountain pass, pass, saddle (landform), saddle, water gap, or wind gap, and geomorphology, geomorphologically is most often carved by water erosion from a freshet, stream or a river. Gaps created by freshets are often, if not normally, devoid of water through much of the year, their streams being dependent upon the meltwaters of a snow pack. Gaps sourced by small spring (hydrology), springs will generally have a small stream excepting perhaps during the most arid parts of the year. Water gaps of necessity often cut entirely through a mountain chain, barrier barrier ridge, range and riverine gaps may create canyons such as the riverine gaps of the Danube River, Lehigh River Gorge, the Colorado River's Grand Canyon and the Genesee River. Such cuttings may expose millennia of strata in the local rock column writing the geologic reco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
