Thecoat of arms of Pennsylvania

Pennsylvania, officially theCommonwealth of Pennsylvania, is astate located in theMid-Atlantic,Northeastern,Appalachian, andGreat Lakes regions of theUnited States. It bordersDelaware to its southeast,Maryland to its south, forming theMason-Dixon Line,West Virginia to its southwest,Ohio to its west, theCanadian province ofOntario to its northwest viaLake Erie,New York to its north, and theDelaware River andNew Jersey to its east. Pennsylvania'smost populous city isPhiladelphia, and the state capital isHarrisburg. Among all US states, Pennsylvania is thefifth-most populous with over 13 million residents as of the2020 United States census, theninth-highest by population density, and the33rd-largest by land area. The largestmetropolitan statistical area is thePhiladelphia metropolitan area insoutheastern Pennsylvania, also known as theDelaware Valley and centered on Philadelphia, thesixth-most populous U.S. city. Pennsylvania's second-largest metropolitan area,Greater Pittsburgh, is centered in and aroundPittsburgh, the commonwealth's second-largest city.

Pennsylvania was founded in 1681 through a royalland grant toWilliam Penn, the son ofthe commonwealth's namesake. Before that, between 1638 and 1655, a southeast portion of the state was part ofNew Sweden, aSwedish colony. Established as a haven for religious and political tolerance, theBritishcolonial-eraProvince of Pennsylvania was known for its relatively peaceful relations with native tribes,innovative government system, andreligious pluralism. Pennsylvania played a vital and historic role in theAmerican Revolution and the ultimately successful quest for independence from theBritish Empire, hosting theFirst andSecond Continental Congress inPhiladelphia, the latter of which formed theContinental Army commanded byGeorge Washington in 1775, during theAmerican Revolutionary War, unanimously adopted theDeclaration of Independence the following year. On December 12, 1787, Pennsylvania was the second state to ratify theU.S. Constitution afterDelaware.

TheBattle of Gettysburg, fought in July 1863 aroundGettysburg, was the bloodiest battle of theAmerican Civil War with over 51,000Union andConfederate casualties, and resulted in a repulsion of the Confederacy's invasion of the North. Throughout the late 19th and 20th centuries, the state'ssteel production and manufacturing-based economy contributed to the development of much of the nation's early infrastructure, including key bridges, skyscrapers, and military hardware used in U.S.-led victories inWorld War I,World War II, and theCold War. In the 21st century, Pennsylvania has garnered the nickname "Cellicon State" for the central role of Philadelphia and Pittsburgh in the development ofimmunotherapies to treat different cancers.

Tropical Storm Henri near peak intensity on September 5

Tropical Storm Henri was a moderatetropical storm that struck Florida during the2003 Atlantic hurricane season. The eighth storm of the season, Henri was one of six tropical cyclones to hit the United States in the year. Henri formed from atropical wave in theGulf of Mexico on September 3. Moving generally to the east, it strengthened to reach peak winds of 60 mph (97 km/h) two days later. Henri encountered unfavorable conditions, and it weakened before making landfall on westernFlorida nearClearwater as a tropical depression. Although Henri degenerated into a remnantlow on September 8, the weather system persisted off the east coast of the United States for a few days before moving back ashore over North Carolina. The system brought heavy rainfall across parts of theMid-Atlantic before dissipating on September 17.

Henri caused little damage as a tropical cyclone. In Florida, it dropped heavyrainfall, though damage was limited to minorflooding damage. InDelaware andPennsylvania, damage was greater, where heavy rainfall damaged hundreds of houses and businesses. The resulting floods in Delaware were described as a1 in 500 year event. The total damage by Henri along its path amounted to $19.6 million (2003 USD), but no deaths were reported. (Full article...)

Reservoirs in the watershed include the Hollister Reservoir, the Elmhurst Reservoir, and others. The stream also flows through the Nay Aug Gorge and passes over the Nay Aug Falls, which are on the National Register of Geologic Landmarks. It flows through a concrete channel in its lower reaches. The topography of the watershed contains rolling hills in its upper reaches and the mountainous land of theMoosic Mountains in its lower reaches.

Land uses in the watershed of Roaring Brook include forested land, agricultural land, and developed land such as high-density residential land and downtown commercial land. Abandoned mine land also occurs in the watershed and wetlands occur in some areas. Major roads in the stream's drainage basin include Interstate 380, Interstate 84, Pennsylvania Route 435, Pennsylvania Route 590, and Pennsylvania Route 690.Mills andforges were built along the stream in the late 1700s and early 1800s.
