In the following decades, pioneer settlers arrived in the Alleghenies, especially during Colonial Virginia's Robert Dinwiddie era (1751–58). These included squatters by the Quit-rent Law. Some had preceded the official surveyors using a "hack on the tree and field of corn" marking land ownership approved by the Virginia Colonial Governor who had to be replaced with Governor John Murray, 4th Earl of Dunmore . Trans-Allegheny travel had been facilitated when

During 1753–1754, the British hastily built Fort Prince George before a larger French force drove them off. The French built Fort Duquesne based on LaSalle's 1669 claims. The French and Indian War ,
9344-585: The Ouasioto Mountains and the earliest term Canaraguy (Kanawhans otherwise Canawest ) on the 1671 French map occupied the southerly Alleghenies. They were associated with the Allegheny "Cherokee" and Eastern Siouan as trade-movers and canoe transporters. The Calicuas, an ancient most northern Cherokee, migrated or was pushed from the Central Ohio Valley onto the north eastern slopes of the Alleghenies of
9472-635: The Railroad had already arrived eight years before. Debt-ridden, the Canal company dropped its plan to continue construction of the next 180 miles (290 km) of the Canal into the Ohio Valley. The company had long realized—especially with the difficult experience of digging the Paw Paw Tunnel —that the original plan of construction over the mountains and all the way down the Youghiogheny River to Pittsburgh
9600-603: The Shenandoah Valley and the Allegheny Mountains beyond. The proto-historic Alleghenies can be exampled by the earliest journals of the colonists. According to Batts and Fallows' September, 1671 Expedition, they found Mehetan Indians of Mountain "Cherokee-Iroquois" mix on the New River tributaries. This journal does not identify the "Salt Village", but, that the "Mehetan" were associated with these and today thought to be " Monetons ", Siouans. However, this journal does not identify
9728-477: The U.S. The city lies in the USDA plant hardiness zone 6b except along the rivers where the zone is 7a. The area has four distinct seasons: winters are cold and snowy, springs and falls are mild with moderate levels of sunshine, and summers are warm. As measured by percent possible sunshine, summer is by far the sunniest season, though annual sunshine is low among major US cities at well under 50%. The warmest month of
9856-399: The air and the rivers. The "Renaissance II" project followed in 1977, focused on cultural and neighborhood development. The industrial base continued to expand through the 1970s, but beginning in the early 1980s both the area's steel and electronics industries imploded during national industrial restructuring. There were massive layoffs from mill and plant closures. In the later 20th century,
9984-532: The ancient Messawomeake, Iroquois tradesmen to 1630s Kent Island, by 1710 maps. Sometime before 1712, the Canawest ("Kanawhans"-"Canallaway"-"Canaragay") had moved to the upper Potomac and made a Treaty with the newly established trading post of Fort Conolloway which would become a part of western Maryland during the 1740s. Prior to European exploration and settlement, trails through the Alleghenies had been transited for many generations by American Indian tribes such as
10112-425: The area shifted its economic base to education, tourism, and services, largely based on healthcare/medicine, finance, and high technology such as robotics. Although Pittsburgh successfully shifted its economy and remained viable, the city's population has never rebounded to its industrial-era highs. While 680,000 people lived in the city proper in 1950, a combination of suburbanization and economic turbulence resulted in
10240-528: The borders of Appalachia as defined by the Appalachian Regional Commission , and has long been characterized as the "northern urban industrial anchor of Appalachia." In its post-industrial state, Pittsburgh has been characterized as the "Paris of Appalachia", recognizing the city's cultural, educational, healthcare, and technological resources, and is the largest city in Appalachia. Under
10368-481: The city's population. Pittsburgh also became a main destination of the African-American Great Migration from the rural South during the first half of the 20th century. Limited initially by discrimination, some 95% percent of the men became unskilled steel workers. During World War II , demand for steel increased and area mills operated 24 hours a day to produce 95 million tons of steel for
10496-595: The city's rivers and hollows. The Great Allegheny Passage and Chesapeake and Ohio Canal Towpath connect the city directly to downtown Washington, D.C. (some 335 miles [539 km] away) with a continuous bike/running trail. The city consists of the Downtown area, called the Golden Triangle, and four main areas surrounding it. These surrounding areas are subdivided into distinct neighborhoods (Pittsburgh has 90 neighborhoods). Relative to downtown, these areas are known as
10624-413: The city. However, the city divested from steel and, since the 1990s, Pittsburgh has focused its energies on the healthcare, education, and technology industries. Pittsburgh is home to large medical providers, including the University of Pittsburgh Medical Center , Allegheny Health Network , and 68 colleges and universities , including research and development leaders Carnegie Mellon University and
10752-526: The colonial Alleghenian location of only a few other early colonial trading locations. A general knowledge of these few outposts are more of traditional telling of some local people. However, an example is the "Van Metre" trading house mentioned in an earlier edition of the "Wonderful West Virginia Magazine" being on the South Branches of the upper reaches of the Potomac. Another very early trading house appears on
10880-537: The community and various developers to create a master plan for a mixed-use development that included a riverfront park, office space, housing, health-care facilities, and indoor practice fields for the Pittsburgh Steelers and Pitt Panthers .

The East End of Pittsburgh
11008-464: The downtown skyline, and numerous other residential neighborhoods such as Sheraden and Elliott . Many of Pittsburgh's patchwork of neighborhoods still retain ethnic characters reflecting the city's settlement history. These include: Several neighborhoods on the edges of the city are less urban, featuring tree-lined streets, yards and garages, with a more suburban character. Oakland, the South Side,
11136-522: The east, they are dominated by a high, steep escarpment known as the Allegheny Front . In the west, they slope down into the closely associated Allegheny Plateau , which extends into Ohio and Kentucky . The principal settlements of the Alleghenies are Altoona , State College , and Johnstown, Pennsylvania ; and Cumberland, Maryland . Using the USGS classification of physical geography ( physiography ),
11264-569: The eastern United States. Naturalist John James Audubon reported that by 1851 a few eastern elk ( Cervus canadensis canadiensis ) could still be found in the Alleghany Mountains but that by then they were virtually gone from the remainder of their range. Mammals in the Allegheny region today include whitetail deer , chipmunk , raccoon , skunk , groundhog , opossum , weasel , field mouse , flying squirrel , cottontail rabbit , gray foxes , red foxes , gray squirrels , red squirrels and
11392-636: The entire region are now almost all second- or third-growth forests , the original trees having been removed in the late 19th and (in West Virginia) early 20th centuries. The wild onion known as the ramp ( Allium tricoccum ) is also present in the deeper forests. Certain isolated areas in the High Alleghenies are well known for their open expanses of sphagnum bogs and heath shrubs (e.g., Dolly Sods , Cranberry Glades ). Many plant communities are indeed similar to those of sea-level eastern Canada. But
11520-530: The first systematic geologic study of the whole mountain range. His map labeled the range as the "Alleghanies", but his book was titled On the Appalachian Mountain System . As late as 1867, John Muir —in his book A Thousand Mile Walk to the Gulf —used the word "Alleghanies" in referring to the southern Appalachians. There was no general agreement about the "Appalachians" versus the "Alleghanies" until

There are very few sizable cities in the Alleghenies. The four largest are (in descending order of population): Altoona , State College , Johnstown (all in Pennsylvania) and Cumberland (in Maryland). In the 1970s and '80s,
12032-484: The ill-fated Braddock expedition four years later. In addition to the war, hunting and trading with Indians were primary motivations for white movement across the mountains. Permanent white settlement of the northern Alleghenies was facilitated by the explorations and stories of such noted Marylanders as the Indian fighter and trader Thomas Cresap (1702–90) and the backwoodsman and hunter Meshach Browning (1781–1859). In
12160-656: The larger Appalachian Plateau province. It may be generally defined to the south by the Allegheny Front , and to the east by the Susquehanna River valley. To the west, the Alleghenies grade down into the dissected Allegheny Plateau. The westernmost ridges are considered to be the Laurel Highlands and Chestnut Ridge in Pennsylvania , and Laurel Mountain and Rich Mountain in West Virginia . Big Stone Ridge marks
12288-671: The late 18th century, a massive migration to the Monongahela River basin took place over three main routes: along the old Braddock Road via Winchester, Virginia ; through the Shenandoah Valley to the head of the Cheat River and from there to the Monongahela; and along the Lincoln Highway to Ligonier, Pennsylvania , and thence along Jacob's Creek to the Monongahela. These immigrants were predominantly Scotch-Irish , German , and, to
12416-531: The late 19th century. From northeast to southwest, the Allegheny Mountains run about 300 miles (480 km). From west to east, at their widest, they are about 100 miles (160 km).

The USGS physiographic classification of all land in the United States lists the Allegheny Mountains as a section within
12544-522: The lower streams of the Alleghenies. The Mohetan representative through a Siouan translator explained to Mr Batts and Mr Fallon, Colonel Abraham Woods explorers 1671–2, that he (Moheton Native American ) could not say much about the people below the "Salt Village" because they (Mountain Cherokee) were not associated with them. The Mohetan was armed by this time of 1671 for the Mohetan Representative
12672-558: The mineral-rich Allegheny Mountains led to the region being contested by the French and British Empires, Virginians , Whiskey Rebels , and Civil War raiders . For part of the 20th century, Pittsburgh was behind only New York City and Chicago in corporate headquarters employment; it had the most U.S. stockholders per capita. Deindustrialization in the late 20th century resulted in massive layoffs among blue-collar workers as steel and other heavy industries declined, coinciding with several Pittsburgh-based corporations moving out of
12800-573: The mountains during the warmer seasons. Occasionally, osprey and eagles can be found nesting along the streams. The hawks and owls are the most common birds of prey . The water habitats of the Alleghenies hold 24 families of fish. Amphibian species number about 21, among them hellbenders , lungless salamanders , and various toads and frogs . The Alleghenies provide habitat for about 54 species of common invertebrate . These include Gastropoda , slugs , leech , earthworms and grub worm . Cave crayfish ( Cambarus nerterius ) live alongside
12928-473: The pair. Sewell eventually settled on the eastern side of Sewell Mountain, near present-day Rainelle, West Virginia . They may well have been the first to settle what was then called the "western waters"— i.e. , in the regions where streams flowed westward to the Gulf of Mexico rather than eastward to the Atlantic. Among the first whites to penetrate into the Allegheny Mountains were surveyors attempting to settle

13184-495: The record cold daily maximum is −3 °F (−19 °C), which occurred three times, most recently the day of the all-time record low, while, conversely, the record warm daily minimum is 82 °F (28 °C) on July 1, 1901. Due to elevation and location on the windward side of the Appalachian Mountains, 100 °F (38 °C)+ readings are very rare, and were last seen on July 15, 1995. Average annual precipitation
13312-405: The region, but most of the revenues flowed out of the mountains to the cities of the eastern seaboard where the captains of industry were headquartered. This inequity created a bitter legacy that would last for generations and form the foundation of the mountaineers' poverty and the area's immense environmental degradation . The most momentous disaster to afflict the people of the Alleghenies
13440-600: The region. An expedition under Peter Jefferson and Thomas Lewis in the following year emplaced the " Fairfax Stone " at the source of the North Branch and established a line of demarcation (the " Fairfax Line ") extending from the stone south-east to the headwaters of the Rappahannock River . Lewis' journal of that expedition provides a valuable view of the Allegheny country before its settlement. Jefferson and Joshua Fry 's "Fry-Jefferson Map" of 1751 accurately depicted
13568-519: The reservoir known as Lake Conemaugh . (This body of water had been built as part of the Main Line of Public Works , then abandoned.) With a flow rate that temporarily equalled that of the Mississippi River , the flood killed 2,209 people and caused US$ 17 million of damage (about $ 425 million in 2012 dollars). The American Red Cross , led by Clara Barton and with 50 volunteers, undertook
13696-590: The sixth-best area for U.S. job growth. Pittsburgh is sometimes called the "City of Bridges" for its 446 bridges .

The city's major league professional sports teams include
13824-624: The south shore of the Allegheny River . The Brilliant Branch Bridge was subsequently repaired and was used by AVRR to access the AZCON scrap yard on the north side of the river. In 2003, a segment of the P&;W Subdivision was leased by AVRR and became their main link between the Pittsburgh Line and the Allegheny Subdivision, leaving the Brilliant Branch to be used for local traffic only. In 2015,

East Carson Street has developed as one of the most vibrant areas of the city, packed with diverse shopping, ethnic eateries, vibrant nightlife, and live music venues. In 1993, the Urban Redevelopment Authority of Pittsburgh purchased the South Side Works steel mill property. It collaborated with
14464-400: The war effort. This resulted in the highest levels of air pollution in the city's almost century of industry. The city's reputation as the "arsenal of democracy" was being overshadowed by James Parton 's 1868 observation of Pittsburgh being "hell with the lid off." Following World War II, the city launched a clean air and civic revitalization project known as the "Renaissance," cleaning up
14592-569: The western valleys of the central Allegheny range. The Montaine sites extend from the tributaries of the upper Potomac River region south to the New River tributaries. These also were influenced by the earlier Armstrong culture of the more southwestern portions northern sub-range of the Ouasioto (Cumberland) Mountains and by the more easterly Virginia Woodland people. The Late Woodland Montaine were less influenced by Hopewellian trade from Ohio, although similarly polished stone tools have been found among

From 1891 to 1911, the city's name
15744-416: Was not at all amenable to a large-scale maneuver war and so the actions that the area witnessed for the remainder of the conflict were generally guerrilla in nature. With the further spread of the railroad networks in the 1890s and early 1900s, many new towns developed and thrived in the Alleghenies. The lumbering and coal industries that boomed in the wake of the railroads brought a measure of prosperity to
