Information: - Appalachia is a cultural region in the Eastern United States that stretches from the Southern Tier of New York to northern Alabama, Mississippi and Georgia. While the Appalachian Mountains stretch from Belle Isle (Newfoundland and Labrador) in Canada to Cheaha Mountain in Alabama, the cultural region of Appalachia typically refers only to the central and southern portions of the range. As of the 2010 United States Census, the region was home to approximately 25 million people. - The British Isles are a group of islands off the north-western coast of continental Europe that consist of the islands of Great Britain, Ireland and over six thousand smaller isles. Situated in the North Atlantic, the islands have a total area of approximately 315,159km, and a combined population of just under 70 million. Two sovereign states are located on the islands: Ireland (which covers roughly five-sixths of the island with the same name) and the United Kingdom of Great Britain and Northern Ireland. The British Isles also include three Crown Dependencies: the Isle of Man and, by tradition, the Bailiwick of Jersey and the Bailiwick of Guernsey in the Channel Islands, although the latter are not physically a part of the archipelago. - The United Presbyterian Church in the United States of America (UPCUSA) was the largest branch of Presbyterianism in the United States from May 28, 1958 to 1983. It was formed by the union of the Presbyterian Church in the United States of America (PCUSA), often referred to (inaccurately) as the "Northern" Presbyterian Church, with the United Presbyterian Church of North America (UPCNA), a smaller church of Covenanter-Seceder tradition at a conference in downtown Pittsburgh, Pennsylvania in May 1958. Vigorous ecumenical activity on the part of PCUSA leaders led to this merger, something of a reunion of two long-separated branches of the larger Presbyterian family deriving from the British Isles. - The United Presbyterian Church of North America ( UPCNA ) was an American Presbyterian denomination that existed for one hundred years . It was formed on May 26 , 1858 by the union of the Northern branch of the Associate Reformed Presbyterian Church ( Covenanter and Seceder ) with the Associate Presbyterian Church ( Seceders ) at a convention at the Old City Hall in Pittsburgh . On May 28 , 1958 , it merged with the Presbyterian Church in the United States of America ( PCUSA ) at a conference in Pittsburgh to form the United Presbyterian Church in the United States of America ( UPCUSA ) . It began as a mostly ethnic Scottish denomination , but after some years it grew somewhat more and more ethnically diverse , although universally English - speaking , and was geographically centered in Western Pennsylvania and eastern Ohio , areas of heavy Scottish and Scotch - Irish settlement on the American frontier . Within that territory , a large part of its adherents lived in rural areas , which amplified the denomination 's already highly traditionalist worldview . - Point State Park (locally known as The Point) is a Pennsylvania state park on in Downtown Pittsburgh, Allegheny County, Pennsylvania, USA, at the confluence of the Allegheny and Monongahela rivers, forming the Ohio River. - The Presbyterian Church (USA), or PC(USA), is a mainline Protestant Christian denomination in the United States. A part of the Reformed tradition, it is the largest Presbyterian denomination in the U.S., and known for its relatively progressive stance on doctrine. The PC(USA) was established by the 1983 merger of the Presbyterian Church in the United States, whose churches were located in the Southern and border states, with the United Presbyterian Church in the United States of America, whose congregations could be found in every state. - The Associate Reformed Presbyterian Church (ARPC), as it exists today, is the remnant of a small denomination, which was formed from the Synod of the South, a division of the Associate Reformed Church. The original Associate Reformed Church resulted from a merger of the Associate Presbytery (from the Seceder tradition of the 18th century) and most of the Reformed Presbytery (from the Covenanter tradition of the 17th century) in Philadelphia in 1782. It is one of the oldest of the United States' theologically and socially conservative denominations. - The Presbyterian Church in the United States of America (PCUSA) was the first national Presbyterian denomination in the United States, existing from 1789 to 1958.

Ohio is the 34th largest by area, the 7th most populous, and the 10th most densely populated of the 50 United States. The state's capital and largest city is Columbus. - Steel is an alloy of iron and other elements, primarily carbon, that is widely used in construction and other applications because of its high tensile strength and low cost. Steel's base metal is iron, which is able to take on two crystalline forms (allotropic forms), body centered cubic and face centered cubic (FCC), depending on its temperature. It is the interaction of those allotropes with the alloying elements, primarily carbon, that gives steel and cast iron their range of unique properties. In the body-centred cubic arrangement, there is an iron atom in the centre of each cube, and in the face-centred cubic, there is one at the center of each of the six faces of the cube. Carbon, other elements, and inclusions within iron act as hardening agents that prevent the movement of dislocations that otherwise occur in the crystal lattices of iron atoms. - Pittsburgh is a city in the Commonwealth of Pennsylvania in the United States, and is the county seat of Allegheny County. The Combined Statistical Area (CSA) population of 2,659,937 is the largest in both the Ohio Valley and Appalachia, the second-largest in Pennsylvania after Philadelphia and the 20th-largest in the U.S. Located at the confluence of the Allegheny and Monongahela rivers, which form the Ohio River, Pittsburgh is known as both "the Steel City" for its more than 300 steel-related businesses, and as the "City of Bridges" for its 446 bridges. The city features 30 skyscrapers, two inclines, a pre-revolutionary fortification and the Point State Park at the confluence of the rivers. The city developed as a vital link of the Atlantic coast and Midwest. The mineral-rich Allegheny Mountains made the area coveted by the French and British empires, Virginia, Whiskey Rebels, and Civil War raiders. - The Allegheny Mountain Range also spelled Alleghany, Allegany and, informally, the Allegheniesis part of the vast Appalachian Mountain Range of the eastern United States and Canada where it posed a significant barrier to land travel in less technologically advanced eras.

At the confluence, the Ohio is considerably bigger than the Mississippi (Ohio at Cairo: 281,500cuft/s (7,960m/s); Mississippi at Thebes: 208,200cuft/s (5,897m/s)) and, thus, is hydrologically the main stream of the whole river system, including the Allegheny River further upstream. - The Presbyterian Church in the United States (PCUS, originally Presbyterian Church in the Confederate States of America) was a Protestant Christian denomination in the Southern and border states of the United States that existed from 1861 to 1983.

Philadelphia is the economic and cultural anchor of the Delaware Valleya region located in the Northeastern United States at the confluence of the Delaware and Schuylkill rivers with 7.2million people residing in the eighth-largest combined statistical area in the United States. - A combined statistical area (CSA) is composed of adjacent metropolitan (MSA) and micropolitan statistical areas (SA) in the United States and Puerto Rico that can demonstrate economic or social linkage. The United States Office of Management and Budget defines a CSA as consisting of various combinations of adjacent metropolitan and micropolitan areas with economic ties measured by commuting patterns. These areas that combine retain their own designations as metropolitan or micropolitan statistical areas within the larger combined statistical area.
