Pennsylvania State Song


Pennsylvania State Song

"Pennsylvania"


Lyrics: Eddie Khoury and Ronnie Bonner
Music: Eddie Khoury and Ronnie Bonner
Adoption: 1990

HISTORY
"Pennsylvania," a song written and composed by Eddie Khoury and Ronnie Bonner, is the official state song of Pennsylvania. The song was presented to the General Assembly in 1989 for adoption. "Pennsylvania" portrays the beauty of the state and its contribution to the people of the land, and states that Pennsylvania was "Blessed by God’s own hand." It is widely sung at official functions and public gatherings.  -World Trade Press
LYRICS
Pennsylvania, Pennsylvania,
Mighty is your name,
Steeped in glory and tradition,
Object of acclaim.
Where brave men fought the foe of freedom,
Tyranny decried,
'Til the bell of independence
Filled the countryside.
Pennsylvania, Pennsylvania,
May your future be,
Filled with honor everlasting
As your history.
Pennsylvania, Pennsylvania,
Blessed by God's own hand,
Birthplace of a mighty nation,
Keystone of the land.
Where first our country's flag unfolded,
Freedom to proclaim,
May the voices of tomorrow
Glorify your name.
Pennsylvania, Pennsylvania,
May your future be,
Filled with honor everlasting
As your history.

The Pennsylvania Quarter

The Pennsylvania Quarter

The Pennsylvania quarter, the second coin in the 50 State Quarters® Program, depicts the statue Commonwealth, an outline of the state, the state motto, and a keystone. This design was chosen to further help educate people about the origins of our second state, founded on December 12, 1787.
The Keystone State
The statue Commonwealth, designed by New York sculptor Roland Hinton Perry, is a bronze-gilded 14' 6" high female form that has topped Pennsylvania's state capitol dome in Harrisburg, Pennsylvania, since May 25, 1905. Her right arm extends in kindness and her left arm grasps a ribbon mace to symbolize justice. The image of the keystone honors the states nickname, "The Keystone State." At a Jefferson Republican victory rally in October 1802, Pennsylvania was toasted as "the keystone in the federal union." The modern persistence of this designation is justified in view of the key position of Pennsylvania in the economic, social, and political development of the United States.
Choosing The Design
Selections for the Pennsylvania circulating quarter began on January 30, 1998. Pennsylvania Governor Tom Ridge issued a proclamation establishing a Commemorative Quarter Committee to review possible designs. The 14-member committee included representatives from major cultural, conservation, travel, and tourism organizations; a teacher; a high school student; the president of the state Numismatic Society; and the state treasurer. The governor invited all Pennsylvanians to submit design concepts to the committee and received more than 5,300 ideas. The committee reached consensus on their recommendations, and the governor forwarded five preferred concepts to the United States Mint. 
Four of the designs were recommended by the Citizens Commemorative Coin Advisory Committee and the Fine Arts Commission and approved by the Secretary of the Treasury. From these final four candidates, the governor chose the current design to represent Pennsylvania in the 50 State Quarters® Program.

The 50 State Quarter ProgramSigned into law in 1997, the 50 States Commemorative Coin Program Act has become the most successful numismatic program in American history, with roughly half of the U.S. population collecting the coins, either in a casual manner or as a serious pursuit. The program produces five different reverse designs each year for ten years—each representing a different state—the order of which is determined by the order states were admitted to the Union. Design concepts are submitted to the Secretary of the Treasury by state governors for final approval. The obverse of each quarter is a slight redesign of the quarter's previous design. The cost to manufacture a quarter is about 5 cents, providing a profit of approximately 20 cents per coin. So far, the federal government has made a profit of $4.6 billion from collectors taking the coins out of circulation. In 2009, the U.S. Mint launched a separate program issuing quarters commemorating the District of Columbia and various U.S. territories.

Pennsylvania State Mineral

Pennsylvania State Mineral

Celestine

Mineral Representative of Pennsylvania
DESCRIPTION
Celestine is a strontium sulfate, sometimes containing traces of barium. Also known as celestite, this is by far the most common mineral containing strontium. In addition to its characteristic and most common pale blue color, celestine also occurs as light gray, white, colorless, orange, yellow, pink, greenish-blue, black, and shades of brown. Celestine is a member of the barite group, forming a series with the mineral barite. Since barite and celestine have the same structure and form very similar crystals, the two appear similar, but a flame test can distinguish them.
STATE SYMBOL
Celestine was first discovered in Pennsylvania in the late 18th century by visiting German mineralogists. They brought a specimen back to Germany for analysis and discovered it to be a previously unknown mineral. The collection site was on Brush Mountain, near what is now Bellwood in Blair County, Pennsylvania. The mineral occurred as plates in shaly limestone in the transition between the Silurian Wills Creek and Tonoloway Formations. It is now known to occur in many counties in the state.
The Central Pennsylvania Rock and Mineral Club chose celestine as a candidate for the state mineral, and Pennsylvania schoolchildren initiated a proposal to the state legislature several times. On February 4, 2004, the state house of representatives approved a bill that would make celestine the state mineral. The bill continued to the state senate, but did not get out of committee. Although Pennsylvania does not have an official state mineral, celestine represents the state’s geology and history well.
NAME ORIGIN
The name for this mineral comes from the Latin and Greek words for "celestial" or "heavenly," referring to celestine’s frequent sky-blue color.
FORMATION AND OCCURRENCE
Mainly found in sedimentary rocks, celestine occurs most often as prisms, fibers, grains, and masses, and also as plates and nodules. This mineral also forms as fillings in geodes. It occurs in association with halite, calcite, fluorite, barite, gypsum, and other minerals. Although fine deposits have been discovered in many localities throughout the world, 96 percent of the world’s celestine comes from just four countries: China, Mexico, Spain, and Turkey.
GEOGRAPHIC DISTRIBUTION
Since celestine is widespread, only a few localities for fine and large crystals are listed here.
  • United States: near Bellwood, Blair County, Pennsylvania; Crystal Cave, Put-in-Bay, South Bass Island, Ottawa County, Ohio; Clay Center, Ottawa County, Ohio; Cave-in-Rock, Hardin County, Illinois; Scofield quarry, Maybee, Monroe County, Michigan; Adamsville, Lampasas County, Texas
  • Canada: Dundas, Ontario
  • Mexico: near Matehuela, San Luis Potosi; and Musquiz and Ramos Arizpe, Coahuila
  • Italy: Girgenti, Caltanissetta; and elsewhere in Sicily
  • Germany: Konrad mine, near Salzgitter, Lower Saxony
  • United Kingdom: Yate, near Bristol, England
  • Norway: Bamle
  • Egypt: Jebel Mokattem, near Cairo
  • Madagascar: Sakoany, near Mahajanga (Majunga)
USES
Celestine is a primary ore of strontium. For many years, the principal use of strontium was for manufacturing glass for cathode-ray tubes (CRTs). Flat-panel displays, which have replaced TV glass, contain little or no strontium. Today, the most important use for strontium is pyrotechnics and ferrite ceramic magnets, which have a range of industrial applications.
The colors and luster of this mineral, in addition to its tendency to associate with other colorful minerals, make it a favorite among collectors. A particularly famous combination is pale blue celestine formed with bright yellow sulfur.
FAMOUS EXAMPLES
The largest known celestine crystal was found at Crystal Cave in Put-In-Bay, Ohio, on Lake Erie. It measures 3 feet (1 m) across. At this same location, the largest known celestine geode was also found. It measures 35 feet (10.7 m) in diameter at its widest point.

Pennsylvania State Gemstone

Williamsite

STATUS
Official
DESCRIPTION
Williamsite is a translucent to nearly transparent variety of serpentine and a synonym of the mineral antigorite. It occurs in association with magnetite, chrysotile, olivine, and chromite. Chromite is the mineral responsible for williamsite’s color. A magnesium silicate mineral, williamsite is light green to emerald green, blue-green, or white with black crystals often included. Chrysotile and lizardite are closely related members of the serpentine group.
STATE SYMBOL
Williamsite was first discovered at Woods Chrome, Pennsylvania, in 1849. Today, Line Pit, a chromite mine on the Pennsylvania-Maryland state line, is known for the highest quality williamsite. Mining of chromite, an associate of williamsite and the mineral responsible its color, was an important industry in Pennsylvania in the 19th century.
Although williamsite is actually named for Lewis Williams, who first described it, the name calls to mind Pennsylvania’s founder, William Penn. So although Pennsylvania does not have an official state gemstone, williamsite is representative of the state’s geology and history. Lewis W. Williams also first described zaratite (emerald nickel) the same year he described williamsite.
NAME ORIGIN
Lewis Williams first discovered williamsite at Woods Chrome, Pennsylvania. Antigorite was named for the occurrence at Val Antigorio, Piedmont, Italy.
FORMATION AND OCCURRENCE
Serpentinite is a major rock-forming mineral. It is found in many igneous and metamorphic rocks, and may be responsible for the color of any green rock. Williamsite commonly replaces rocks that contain iron or magnesium but little or no silica. It forms microscopic masses.
GEOGRAPHIC DISTRIBUTION
Williamsite is fairly widespread. The following is a list of some localities with well-studied material:
  • Italy: Val Antigorio, Piedmont
  • Austria: Prägraten, Tirol
  • Scotland: Glen Urquhart, Inverness-Shire
  • China: Hsiu-Yen Hsien, Liaoning Province
  • Japan: Nishisonnogi area, Nagasaki Prefecture, and the Sasagure area, Fukuoka Prefecture
  • Australia: Woodsreef, New South Wales
  • United States: Chester and Lancaster counties, Pennsylvania; Baltimore City and Baltimore County, Maryland; Brewster, Putnam County, New York; and Buck Creek, Clay County, North Carolina
  • Canada: Asbestos, Quebec, and Timmins, Ontario
USES
Williamsite is cut into cabochons and beads for use in jewelry.

Anthracite Coal

STATUS
Unofficial
DESCRIPTION
Anthracite is a hard, lustrous, high-carbon variety of coal. Coal, a brittle, combustible, black or dark brown sedimentary rock, forms from decomposed plant matter that has been subjected to high temperatures. Coal is composed primarily of carbon, with traces of sulfur, hydrogen, and nitrogen.
It is grouped into four ranks according to its carbon content. Anthracite, the highest rank, is over 95 percent carbon and has been partially metamorphosed. In descending rank, the other coals are bituminous (at least 90 percent carbon), sub-bituminous (at least 85 percent), and lignite, which grades into peat. The density of anthracite is 1.3–1.4, higher than other ranks of coal (but only about half as dense as granite or basalt).
A STATE SYMBOL
While Pennsylvania has never designated an official state rock, anthracite coal is an obvious choice because of its economic and historical importance to the state and the nation.
Coal was known to exist in Pennsylvania as early as 1752 near what is now the town of Saltsburg. However, this coal was never mined commercially. By 1761, the phenomenal Pittsburgh coal bed had been discovered. Coal from this bed, underlying large parts of Pennsylvania, West Virginia, Ohio, and Maryland, was a major fuel of the region’s Industrial Revolution and continues to be mined today in 21 counties.
The state’s anthracite deposits, in the eastern part of the state, are smaller in extent but larger in significance. Only about 1.5 percent of coal is anthracite, and Pennsylvania has more anthracite than any other place in the world.
FORMATION
Coal formation began about 350 million years ago in the Carboniferous Period, a time of mild climate and prevalent swamplands. Throughout millions of years, swamp plants that died built up in layers of peat, which was initially about 90 percent water. Aerobic decay in the upper layers of the swamp began the decomposition process, reducing the volume of the organic matter.
Beneath these upper layers, where oxygen did not penetrate, anaerobic bacteria further broke down the plant remains. These bacteria gave off acids, which, at still deeper levels, became too concentrated for bacteria to live. The acidic, anaerobic plant matter had by this time been transformed into a black gel known as gytta, and it no longer underwent decomposition.
The next step in the development of coal was bituminization, which occurred over millions of years as a sedimentary blanket thousands of feet thick buried the ancient swamps, trapping heat rising from deep in the earth. The high temperatures caused the water content to be cooked out of the peat until it formed lignite. If the process continued long enough, the water and organic matter in the peat continued to be forced out, creating purer coal.
Pennsylvania’s anthracite formed in the Pennsylvanian Epoch, which is the term used for the latter half of the Carboniferous Period. Successive generations of swamps in river floodplains and along the coast laid down deposits of peat, which were covered by larger deposits of sediment over many cycles. The sand and silt layers became sandstone, shale, and limestone, while the peat layers evolved into coal. Later mountain-building events would uplift, fold, and deform these sedimentary beds.
GEOGRAPHIC DISTRIBUTION
Worldwide, recoverable coal exists in about 70 countries. The U.S, Russia, China, and India have by far the largest proven reserves of coal. The two principal anthracite beds of Pennsylvania stretch in northeast-to-southwest oriented bands in the eastern part of the state. The counties with the richest sources are Lackawanda, Luzerne, Carbon, Schuylkill, and Northumberland. In addition, the vast field of bituminous coal underlies Pennsylvania’s southwestern quadrant. In all, 266 mines in 28 counties produce coal.
USES
Coal has been burned in stoves for centuries as a direct source of heat. In modern times, the greatest demand for coal is industrial. Electricity generation from "steam coal" is the most significant of these uses; worldwide, 41.5 percent of electricity is produced in coal-fired power plants.
Coal has other uses besides generating energy. The manufacture of steel requires carbon, most often obtained from metallurgical (hard) coal. Thirteen percent of the world’s hard coal is used to make steel. A surprising array of products is made using coal or its by-products, including paper, creosote, benzene, ammonia, pharmaceuticals, fibers (rayon, nylon), dyes, and solvents.
PRODUCTION
In 2008, Pennsylvania mined 65.4 million tons of coal, of which 1.7 million tons were anthracite from 66 mines. Pennsylvania was the only U.S. state to produce any anthracite. Total U.S. production of all ranks of coal in 2008 was 1.2 billion tons. World production of all ranks of coal in 2008 was 6.8 billion tons.

HISTORY
The Commonwealth of Pennsylvania was at the center of the birth of the United States. It held its first constitutional convention less than two weeks after the young country had declared independence from Britain in 1776. By September of that year, delegates had been elected and a new state constitution and bill of rights had been signed. The new constitution did away with the former frame of government, which had been established by William Penn in 1682, and was represented by a governor and provincial assembly. The document eventually became a model for democratic governance, including the abolition of slavery.
MOTTO
"Virtue, Liberty, and Independence"
Pennsylvania’s motto harkens back to the days of the Revolutionary War and the state’s first tumultuous years. The motto appears on the Pennsylvania coat of arms, which was designed by Caleb Lownes in 1778, barely two years after Pennsylvania reached statehood.
NICKNAMES
"The Keystone State," "The Liberty Bell State," "The Quaker State"
The earliest documented instance of Pennsylvania’s widely accepted nickname "The Keystone State" was at a Republican victory rally in 1802, when the state was referred to as "the keystone in the federal union." Philadelphia is home to the famed Liberty Bell—said to have been rung on July 8, 1776, to call citizens to hear the new Declaration of Independence—hence the nickname "The Liberty Bell State." "The Quaker State" pays homage to the state’s early founders and residents, who were largely Quakers.

Pennsylvania: A Historical Timeline

Pennsylvania: A Historical Timeline


PRIOR TO 1608
PRE-EUROPEAN SETTLEMENT

Native Americans live in the geographical region now known as Pennsylvania long before Europeans explore the area. The two primary groups are the Algonquin and the Iroquois. Native Americans travel around the area by canoe or on foot. Although some farming is done, most food is acquired through hunting and gathering.
1608-1679
EARLY EUROPEAN EXPLORATION AND SETTLEMENT
1608
Captain John Smith journeys up the Susquehanna River from Virginia, visiting the Susquehannock Native Americans.
1609
Henry Hudson, an Englishman sailing for the Dutch, sails the Half Moon into Delaware Bay, giving the Dutch claim to the area.
1610
Captain Samuel Argall of Virginia visits the bay and names it for Lord de la Warr, governor of Virginia.
1638
The Swedish are the first to make a permanent settlement when the colony of New Sweden is established.
