Blue Ridge Mountains in the context of "Appalachia"

Virginia, officially the Commonwealth of Virginia, is a state in the Southeastern and Mid-Atlantic regions of the United States between the Atlantic Coast and the Appalachian Mountains. The state's capital is Richmond and its most populous city is Virginia Beach. Its most populous subdivision is Fairfax County, part of Northern Virginia, where slightly over a third of Virginia's population of more than 8.8 million live.

Eastern Virginia is part of the Atlantic Plain, and the Middle Peninsula forms the mouth of the Chesapeake Bay. Central Virginia lies predominantly in the Piedmont, the foothill region of the Blue Ridge Mountains, which cross the western and southwestern parts of the state. The fertile Shenandoah Valley fosters the state's most productive agricultural counties, while the economy in Northern Virginia is driven by technology companies and U.S. federal government agencies. Hampton Roads is also the site of the region's main seaport and Naval Station Norfolk, the world's largest naval base.

Tennessee (/ˌtɛnɪˈsiː/ , locally /ˈtɛnɪsi/), officially the State of Tennessee, is a landlocked state in the Southeastern region of the United States. It borders Kentucky to the north, Virginia to the northeast, North Carolina to the east, Georgia, Alabama, and Mississippi to the south, Arkansas to the southwest, and Missouri to the northwest. Tennessee is the 36th-largest by area and the 15th-most populous of the 50 states. According to the United States Census Bureau, the state's estimated population as of 2024 is 7.22 million.

Tennessee is geographically, culturally, and legally divided into three Grand Divisions of East, Middle, and West Tennessee. Nashville is the state's capital and largest city, and anchors its largest metropolitan area. Tennessee has diverse terrain and landforms, and from east to west, contains a mix of cultural features characteristic of Appalachia, the Upland South, and the Deep South. The Blue Ridge Mountains along the eastern border reach some of the highest elevations in eastern North America, and the Cumberland Plateau contains many scenic valleys and waterfalls. The central part of the state is marked by cavernous bedrock and irregular rolling hills, and level, fertile plains define West Tennessee. The state is twice bisected by the Tennessee River, and the Mississippi River forms its western border. The Great Smoky Mountains National Park, the nation's most visited national park, is in eastern Tennessee.

A wind gap (or air gap) is a gap through which a waterway once flowed that is now dry as a result of stream capture. A water gap is a similar feature, but one in which a waterway still flows. Water gaps and wind gaps often provide routes which, due to their gently inclined profile, are suitable for trails, roads, and railroads through mountainous terrain.

Examples of wind gaps in the Blue Ridge Mountains of Virginia include Swift Run Gap, Rockfish Gap, and Buford's Gap. The last was the original crossing of the Blue Ridge Mountains near Bedford for the Virginia and Tennessee Railroad, later the Norfolk and Western Railway, a precursor of today's Norfolk Southern Railway system. Another wind gap with substantial importance in U.S. history is the Cumberland Gap near the junction of Kentucky, Virginia, and Tennessee.

U.S. Route 522 (US 522) is a spur route of US 22 in the states of Virginia, West Virginia, Maryland, and Pennsylvania. The U.S. Highway travels in a north-south direction, and runs 308.59 miles (496.63 km) from US 60 near Powhatan, Virginia, to its northern terminus at US 11 and US 15 near Selinsgrove, Pennsylvania. US 522 serves many small cities and towns in the Piedmont, Blue Ridge Mountains, and northern Shenandoah Valley of Virginia. The highway serves the Virginia communities of Goochland, Mineral, Culpeper, the town of Washington, and Front Royal and the independent city of Winchester. US 522 then follows the Ridge-and-Valley Appalachians north and then east through the Eastern Panhandle of West Virginia, a 2-mile-wide (3.2 km) stretch of Western Maryland, and South Central Pennsylvania to its terminus in the Susquehanna Valley. The highway serves Berkeley Springs, West Virginia; Hancock, Maryland; and the Pennsylvania communities of McConnellsburg, Mount Union, Lewistown, and Middleburg.

Lynchburg is an independent city in the Commonwealth of Virginia, United States. Located in the foothills of the Blue Ridge Mountains along the James River, it had a population of 79,009 at the 2020 census, making it the 11th most populous independent city in Virginia. The city is nicknamed the "City of Seven Hills" or the "Hill City." Lynchburg was founded in 1757 by John Lynch, a Quaker ferry operator and abolitionist. During the American Civil War, Lynchburg’s strategic importance helped it remain the only major city in Virginia not recaptured by Union forces before the war’s end.

Lynchburg anchors the Lynchburg Metropolitan Statistical Area (MSA) which lies near the geographic center of Virginia and is the fifth-largest MSA in the state with a population of 261,593. The city is a regional hub for education, home to several institutions of higher learning including Liberty University, the University of Lynchburg, Randolph College, Virginia University of Lynchburg, and Central Virginia Community College.

Interstate 64 (I-64) in the US state of Virginia runs east–west through the middle of the state from West Virginia to the Hampton Roads region, for a total of 299 miles (481 km). From the West Virginia state line to Chesapeake, it passes through the major cities of Lexington, Staunton, Charlottesville, the state capital of Richmond, Newport News, Hampton, and Norfolk. It is notable for crossing the mouth of the harbor of Hampton Roads on the Hampton Roads Bridge–Tunnel (HRBT), the first bridge–tunnel to incorporate artificial islands, concurrent with U.S. Route 60 (US 60). Also noteworthy is a section through Rockfish Gap, a wind gap in the Blue Ridge Mountains, which was equipped with an innovative system of airport-style runway lighting embedded into the pavement to aid motorists during periods of poor visibility due to fog or other conditions.

Short Pump is a census-designated place (CDP) in Henrico County, Virginia, United States. It is a borough of Richmond. The population was 30,626 at the 2020 census.

The original village of Short Pump was located at the intersection of Three Chopt Road (formerly known as Three Notched Trail), Richmond Turnpike and Pouncey Tract Road. The area first centered around a local tavern that was expanded by Col. Robert H. Saunders beginning in 1814. According to local legend, it was named for the short handled water pump for stagecoach horses to drink from, which was located beneath the porch of the tavern, though there is some debate over the name's origin. This area was on the principal route between Richmond and Charlottesville, as well as other towns in the Blue Ridge Mountains. Thomas Jefferson, the Earl Cornwallis, the Marquis de Lafayette, General Peter Muhlenberg, Stonewall Jackson and Ulric Dahlgren all visited this area.

The Catawba River is a major river located in the Southeastern United States. It originates in Western North Carolina and flows into South Carolina, where it later becomes known as the Wateree River. The river is approximately 220 miles (350 km) long. It rises in the Appalachian Mountains and drains into the Piedmont, where it has been impounded through a series of reservoirs for flood control and generation of hydroelectricity. The river is named after the Catawba tribe of Native Americans, which lives on its banks. In their language, they call themselves "yeh is-WAH h’reh", meaning "people of the river."

The river rises in the Blue Ridge Mountains in western McDowell County, North Carolina, approximately 20 miles (30 km) east of Asheville. It flows east-northeast, falling over two waterfalls, Upper Catawba Falls and Catawba Falls, before being dammed by Lake James, and joining the Linville River. It passes north of Morganton, then southeast through Lake Rhodhiss and Lake Hickory just north of Hickory, and into the Lake Norman reservoir. From Lake Norman it flows south, passing west of Charlotte, then flowing through the Mountain Island Lake and Lake Wylie reservoirs, where it exits the reservoirs approximately 10 miles (15 km) south of the border between North Carolina and South Carolina. The confluence of the South Fork Catawba River and Catawba River is submerged by Lake Wylie near the NC/SC state line.

Leucogranite is a light-colored, granitic, igneous rock containing almost no dark minerals.

Leucogranites have been reported from a variety of orogenies involving continental collisions. Examples include the Black Hills (Trans-Hudson orogeny of Proterozoic age), the Blue Ridge basement complex (Grenville orogeny of Proterozoic age), the Paleozoic Appalachian orogeny in Maine, and the currently active Himalayan orogeny. The leucogranite magmas are interpreted to have been derived by partial melting of pelitic rocks in the upper portions of thickened crust. These melts result following deformation and metamorphism, but the heat source is uncertain. Shear-heating associated with large shear zones in the crust has been proposed as the mechanism.
