The National Road was the first major improved highway in the United States built by the federal government. Built between 1811 and 1837, the 620-mile (1,000 km) road connected the Potomac and Ohio Rivers and was a main transport path to the West for thousands of settlers. When improved in the 1830s, it became the second U.S. road surfaced with the macadam process pioneered by Scotsman John Loudon McAdam.
Gallitzin is a borough in Cambria County, Pennsylvania, United States. It is bordered by Gallitzin Township and Tunnelhill, all of which sit astride the Eastern continental divide. Tunnel Hill and Gallitzin both are pierced by railroad tunnels shortening the necessary ascent for rails crossing the Allegheny Front onto the Allegheny Plateau which encompasses the towns' terrains. Topping the gaps of the Allegheny, the area is one of only five major breaks in the Appalachians allowing east–west transportation corridors before the advent of 20th century technologies.
The Great Appalachian Valley, also called The Great Valley or Great Valley Region, is one of the major landform features of eastern North America. It is a gigantic trough—a chain of valley lowlands—and the central feature of the Appalachian Mountains system. The trough stretches about 1,200 miles (1,900 km) from Quebec in the north to Alabama in the south and has been an important north–south route of travel since prehistoric times.
Allegheny, Alleghany or Allegany may refer to:
The Allegheny Mountain Range, informally the Alleghenies, is part of the vast Appalachian Mountain Range of the Eastern United States and Canada and posed a significant barrier to land travel in less developed eras. The Allegheny Mountains have a northeast–southwest orientation, running for about 400 miles (640 km) from north-central Pennsylvania, southward through western Maryland and eastern West Virginia.
The Eastern Continental Divide, Eastern Divide or Appalachian Divide is a hydrographic divide in eastern North America that separates the easterly Atlantic Seaboard watershed from the westerly Gulf of Mexico watershed. The divide nearly spans the United States from south of Lake Ontario through the Florida peninsula, and consists of raised terrain including the Appalachian Mountains to the north, the southern Piedmont Plateau and lowland ridges in the Atlantic Coastal Plain to the south. Water including rainfall and snowfall, lakes, streams and rivers on the eastern/southern side of the divide drains to the Atlantic Ocean; water on the western/northern side of the divide drains to the Gulf of Mexico. The ECD is one of six continental hydrographic divides of North America which define several drainage basins, each of which drains to a particular body of water.
The Allegheny Plateau is a large dissected plateau area of the Appalachian Mountains in western and central New York, northern and western Pennsylvania, northern and western West Virginia, and eastern Ohio. It is divided into the unglaciated Allegheny Plateau and the glaciated Allegheny Plateau.
The Ridge-and-Valley Appalachians, also called the Ridge and Valley Province or the Valley and Ridge Appalachians, are a physiographic province of the larger Appalachian division and are also a belt within the Appalachian Mountains extending from southeastern New York in the north through northwestern New Jersey, westward into Pennsylvania through the Lehigh Valley, and southward into Maryland, West Virginia, Virginia, Kentucky, Tennessee, Georgia, and Alabama. They form a broad arc between the Blue Ridge Mountains and the Appalachian Plateau physiographic province. They are characterized by long, even ridges, with long, continuous valleys in between.
The Kittanning Path was a major east-west Native American trail that crossed the Allegheny Mountains barrier ridge connecting the Susquehanna River valleys in the center of Pennsylvania to the highlands of the Appalachian Plateau and thence to the western lands beyond drained by the Ohio River. Kittanning Village was the first major Delaware (Lenape) Indian settlement along the descent from the Allegheny Plateau.
Kittanning Gap, one of the gaps of the Allegheny, is a now a relatively unimportant wooded ravine along the ascent of the Allegheny Ridge (also called the 'Allegheny Front' or 'Allegheny escarpment') in central Pennsylvania in the United States. The gap was one of several optional paths of the Kittanning Path Amerindian trail turned into an emigrant route over the Alleghenies in the day of animal powered technology. The option up the gap was likely the 'better choice' of an ascending route for ox cart and wagon encumbered white settlers pouring west across the Alleghenies escarpment.
The Allegheny Front is the major southeast- or east-facing escarpment in the Allegheny Mountains in southern Pennsylvania, western Maryland, eastern West Virginia, and western Virginia, USA. The Allegheny Front forms the boundary between the Ridge-and-Valley Appalachians to its east and the Appalachian Plateau to its west. The Front is closely associated with the Appalachian Mountains' Eastern Continental Divide, which in this area divides the waters of the Ohio/Mississippi river system, flowing to the Gulf of Mexico, from rivers flowing into Chesapeake Bay and from there into the Atlantic Ocean.
The Great Allegheny Passage (GAP) is a 150-mile (240 km) rail trail between Pittsburgh, Pennsylvania and Cumberland, Maryland. Together with the C&O Canal towpath, the GAP is part of a 335 mi (539 km) route between Pittsburgh and Washington, D.C., that is popular with through hikers and cyclists.
The Potomac Highlands of West Virginia centers on five West Virginian counties in the upper Potomac River watershed in the western portion of the state's Eastern Panhandle, bordering Maryland and Virginia. Because of geographical proximity, similar topography and landscapes, and shared culture and history, the Potomac Highlands region also includes Pocahontas, Randolph, and Tucker counties, even though they are in the Monongahela River or New River watersheds and not that of the Potomac River.
The Great Indian Warpath (GIW)—also known as the Great Indian War and Trading Path, or the Seneca Trail—was that part of the network of trails in eastern North America developed and used by Native Americans which ran through the Great Appalachian Valley. The system of footpaths extended from what is now upper New York to deep within Alabama. Various Indians traded and made war along the trails, including the Catawba, numerous Algonquian tribes, the Cherokee, and the Iroquois Confederacy. The British traders' name for the route was derived from combining its name among the northeastern Algonquian tribes, Mishimayagat or "Great Trail", with that of the Shawnee and Delaware, Athawominee or "Path where they go armed".
Wills Mountain is a quartzite-capped ridge in the Ridge and Valley physiographic province of the Appalachian Mountains in Pennsylvania and Maryland, United States, extending from near Bedford, Pennsylvania, to near Cumberland, Maryland. It is the northernmost of several mountain ridges included within the Wills Mountain Anticline.
The Cumberland Narrows is a water gap in western Maryland in the United States, just west of Cumberland. Wills Creek cuts through the central ridge of the Wills Mountain Anticline at a low elevation here between Wills Mountain to the north and Haystack Mountain to the south. Cliffs and talus of the two mountains' Tuscarora quartzite caprock are prominent within the Narrows. A prominent rocky outcropping at the south end of Wills Mountain in the Cumberland Narrows is known as Lover's Leap.
The Silurian Tuscarora Formation — also known as Tuscarora Sandstone or Tuscarora Quartzite — is a mapped bedrock unit in Pennsylvania, Maryland, West Virginia, and Virginia, USA.
Brownsville Road is a road between Pittsburgh, at Eighteenth Street and South Avenue in Allegheny County, Pennsylvania eastwards through Mount Oliver and generally highlands situated along or near the hilltops often overlooking the Monongahela River. It has had several names over its history, and was also known at the Red Stone Road and the period it was a Plank Road managed as a toll road, the Brownsville Plank Road, or the Brownsville Turnpike, or locally, as the area grew into a city, Southern Avenue.
The Kittanning Run is one of the several streams draining the Allegheny Plateau, each one cutting an abrupt valley, one of the gaps of the Allegheny— one of several climbing valleys used for centuries by the Amerindian native peoples to pass East-to-West through the Allegheny Front escarpment, a barrier ridge separating the flat highlands plateau, the Appalachian Plateau—from the many barrier ridges making up the local Ridge-and-Valley Appalachians in the Central Pennsylvania heartland.
The gaps of the Allegheny, meaning gaps in the Allegheny Ridge in west-central Pennsylvania, is a series of escarpment eroding water gaps along the saddle between two higher barrier ridge-lines in the eastern face atop the Allegheny Ridge or Allegheny Front escarpment. The front extends south through Western Maryland and forms much of the border between Virginia and West Virginia, in part explaining the difference in cultures between those two post-Civil War states. While not totally impenetrable to daring and energetic travelers on foot, passing the front outside of the water gaps with even sure footed mules was nearly impossible without navigating terrain where climbing was necessary on slopes even burros would find extremely difficult.
