Map of Appalachian Mountains
Appalachian Mountains or Appalachians, great mountain system of eastern North America, nearly parallel with the Atlantic coast, and extending from the province of Québec in Canada to northern Alabama. The system is 2,400 km (1,500 mi) long and varies from 160 to more than 480 km (100 to more than 300 mi) in width. Its altitude varies between 460 and nearlyy 2,040 m (1,500 and nearly 6,700 ft). The three divisions of the system—northern, central, southern—vary considerably in geologic age, having been raised by a series of crustal plate collisions that began during the Ordovician period and climaxed in the Permian (see Plate Tectonics).

The Republican Party was born out of the great political crisiss of the 1850s. During that decade, Americans grew fearful that their experiment in self-government was falling apart. Disagreement over the fate of slavery was the prime force behind this crisis, but European immigration, westward expansion, industrialization, and political corruption also troubled Americans, especially northerners who lived amidst the greatest changes.

The Appalachian Revolution contributed to another, more recent upheaval: the Industrial Revolution. Anthracite kept millions warm in growing cities, fired furnaces in the industrial northeast, spawned extensive transportation networks, provided jobs for immigrants seeking better lives, gave rise to the development of modern corporations and management practices
In northeastern Pennsylvania, however, the ordinary process of coal formation was accelerated by a violent upheaval known as the Appalachian Revolution. In this "revolution," rising mountains literally folded over, splitting open and thrusting up rock and peat formations from deep inside the earth. The extra pressure from this process yielded coal that was more pure, harder, and of higher carbon content than other types of coal. This coal is anthracite and over 95 percent of the Western Hemisphere's supply comes from this special region in northeastern Pennsylvania.

Pennsylvania State Flag

Pennsylvania's State Flag is more of a square than a rectangle. It is composed
of a blue field on which the State Coat of Arms is embroidered. Draft horses are on either side of the coat of arms and the American eagle rests on the top. The scroll at the bottom reads Virtue, Liberty and Independence.

The Monongahela River (affectionately referred to as The Mon) is a river on the Allegheny Plateau in West Virginia and Pennsylvania in the United States. At Pittsburgh, it meets the Allegheny River to form the Ohio River.

The Monongahela is formed by the conflluence of the West Fork River and the Tygart Valley River at Fairmont, West Virginia. It is one of the largest rivers in the United States to flow generally northward. The river is navigable its entire length with a series of lock/dams ensuring a 9' depth. In Pennsylvania, the Monongahela is met by two major tributaries: the Cheat River, which joins at Point Marion; and the Youghiogheny River, which joins at McKeesport.
