Saint Peter's Village
Saint Peters is an historic, nineteenth-century, industrial, company village that is located in Chester County, Pennsylvania, United States. Built near the Falls of French Creek in Warwick Township, it is situated in the Hopewell Big Woods. Geography The town is located in a narrow ravine along French Creek. The Falls of French Creek have formed where French Creek cuts across a series of diabase (trap rock) dikes. Erosion of the diabase dikes by the creek has caused huge boulders to fall into the stream, almost filling the creek bed at points. The igneous intrusion that produced these diabase dikes also replaced limestone or marble in the surrounding rock with iron ores. History The presence of iron ore led to the establishment of the French Creek iron mines in 1845. In 1880, quarrying of the diabase, known locally as "black granite", began, and the "Excursion House" hotel opened, distinguishing the community as both an industrial village and recreational weekend retreat. ...

Trap Rock
Trap rock, also known as either trapp or trap, is any dark-colored, fine-grained, non-granitic intrusive or extrusive igneous rock. Types of trap rock include basalt, peridotite, diabase, and gabbro.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, J.A., eds. (2005) ''Glossary of Geology'' (5th ed.) American Geological Institute, Alexandria, Virginia. 779 pp. Trap is also used to refer to flood (plateau) basalts, such as the Deccan Traps and Siberian Traps.Le Maitre, R. W., ed. (2002) ''Igneous Rocks: A Classification and Glossary of Terminology''. Cambridge University Press, New York. 236 pp. The erosion of trap rock created by the stacking of successive lava flows often creates a distinct stairstep landscape from which the term ''trap'' was derived from the Swedish word , which means "stairs". The slow cooling of magma either as a sill or as a thick lava flow sometimes creates systematic vertical fractures within the resulting layer of trap rock. These fractures of ...

Tourist Attractions In Chester County, Pennsylvania
Tourism is travel for pleasure, and the commercial activity of providing and supporting such travel. UN Tourism defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "travelling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours, business and other purposes". Tourism can be domestic (within the traveller's own country) or international. International tourism has both incoming and outgoing implications on a country's balance of payments. Between the second half of 2008 and the end of 2009, tourism numbers declined due to a severe economic slowdown (see Great Recession) and the outbreak of the 2009 H1N1 influenza virus. These numbers, however, recovered until the COVID-19 pandemic put an abrupt end to the growth. The United Nations World Tourism Organization has estimated that global international tourist a ...

National Register Of Historic Places
The National Register of Historic Places (NRHP) is the Federal government of the United States, United States federal government's official United States National Register of Historic Places listings, list of sites, buildings, structures, Historic districts in the United States, districts, and objects deemed worthy of Historic preservation, preservation for their historical significance or "great artistic value". The enactment of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing property, contributing resources within historic district (United States), historic districts. For the most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the United States Department of the Interior. Its goals are to ...

Delaware River And Lancaster Railroad
The Delaware River and Lancaster Railroad, known locally as the Sowbelly Railroad, was a short-lived rail line along French Creek between Kimberton and St. Peters in Chester County, Pennsylvania. Planned interstate line The railroad was originally chartered on March 24, 1868, to run from a railroad bridge crossing the Delaware River at Point Pleasant, Pennsylvania, via Phoenixville, Pennsylvania to Lancaster, Pennsylvania, as part of a more direct route between New York City and Lancaster. The charter required the railroad to begin construction within two years of the passage of the act. A supplemental act of February 10, 1870 extended that time by a further three years. The company was not organized until October 12, 1871. It received a charter supplement on April 4, 1872, relieving it of the need to pass through Phoenixville. A token amount of work to preserve the company's charter was done in the winter of 1872–3, when George W. Crane graded about of the line on the Chris ...

Reading Company
The Reading Company ( ) was a Philadelphia-headquartered railroad that provided passenger and freight transport in eastern Pennsylvania and neighboring states from 1924 until its acquisition by Conrail in 1976. Commonly called the Reading Railroad and logotyped as Reading Lines, the Reading Company was a railroad holding company for most of its existence, and a single railroad in its later years. It operated service as Reading Railway System and was a successor to the Philadelphia and Reading Railway Company, founded in 1833. Until the decline in anthracite shipments from the Coal Region in Northeastern Pennsylvania following World War II, it was one of the most prosperous corporations in the United States. Enactment of the federally-funded Interstate Highway System in 1956 led to competition from the modern trucking industry. They used the Interstates for short-distance transportation of goods, which compounded the company's competition for freight business, forcing it into ba ...

Iron Ore
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (, 72.4% Fe), hematite (, 69.9% Fe), goethite (, 62.9% Fe), limonite (, 55% Fe), or siderite (, 48.2% Fe). Ores containing very high quantities of hematite or magnetite (typically greater than about 60% iron) are known as natural ore or irect shipping ore and can be fed directly into iron-making blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel — 98% of the mined iron ore is used to make steel. In 2011 the ''Financial Times'' quoted Christopher LaFemina, mining analyst at Barclays Capital, saying that iron ore is "more integral to the global economy than any other commodity, except perhaps oil". Sources Elemental iron is virtually absent o ...

Marble
Marble is a metamorphic rock consisting of carbonate minerals (most commonly calcite (CaCO3) or Dolomite (mineral), dolomite (CaMg(CO3)2) that have recrystallized under the influence of heat and pressure. It has a crystalline texture, and is typically not Foliation (geology), foliated (Layered intrusion, layered), although there are exceptions. In geology, the term ''marble'' refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. The extraction of marble is performed by quarrying. Marble production is dominated by four countries: China, Italy, India and Spain, which account for almost half of world production of marble and decorative stone. Because of its high hardness and strong wear resistance, and because it will not be deformed by temperature, marble is often used in Marble sculpture, sculpture and construction. Etymology The word "marble" derives from the Ancient Greek (), from (), "crystalline rock, shin ...

Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly Dolomite (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...

Dike (geology)
In geology, a dike or dyke is a sheet of rock that is formed in a fracture of a pre-existing rock body. Dikes can be either magmatic or sedimentary in origin. Magmatic dikes form when magma flows into a crack then solidifies as a sheet intrusion, either cutting across layers of rock or through a contiguous mass of rock. Clastic dikes are formed when sediment fills a pre-existing crack.Essentials of Geology, 3rd Ed, Stephen Marshak Magmatic dikes A magmatic dike is a sheet of igneous rock that cuts across older rock beds. It is formed when magma fills a fracture in the older beds and then cools and solidifies. The dike rock is usually more resistant to weathering than the surrounding rock, so that erosion exposes the dike as a natural wall or ridge. It is from these natural walls that dikes get their name. Dikes preserve a record of the fissures through which most mafic magma (fluid magma low in silica) reaches the surface. They are studied by geologists for the clues they ...
