Conewago Mountains
The Conewago Mountains or Conewago Hills are a low range of mountains in northern York County, Pennsylvania. They run northeasterly across the county. They form the backdrop to Gifford Pinchot State Park and parallel Conewago Creek. The Conewago Mountains played a role in the early colonization and settling of the region, with settlers north of the mountains being predominantly Scotch-Irish and those south of the range being mostly Germans from the Palatinate region. The mountains provided a source of timber and firewood, and small iron foundries dotted the valley below to smelt iron ore taken from the Conewagos. During the American Civil War, Confederate cavalry under J.E.B. Stuart crossed over the mountains at the hamlet of Mount Royal in Dover Township en route from the Battle of Hanover to Carlisle. Scores of farms in the region were raided for horses, and many farmers hid their livestock in the Conewago Mountains to secret them from the passing Confederates. Today, the mou ...

Gettysburg Formation
The Gettysburg Formation is a mapped bedrock unit consisting primarily of sandstones, conglomerates, and shales. The Gettysburg Formation was first described in the Gettysburg area of Adams County, Pennsylvania in 1929, and over the following decade was mapped in adjacent York County, PennsylvaniaStose, G.W., and Jonas, A.I., 1939, Geology and mineral resources of York County, Pennsylvania: Pennsylvania Geological Survey County Report, 4th series, no. 67, 199 p. and Frederick County, Maryland. It was then typically called the "Gettysburg shale," and was described as "thick red shales and soft red sandstones." The majority of this early mapping was done by G. W. Stose, A. I. Jonas, and Florence Bascom. Later workers described it as "Red, medium- to fine-grained sandstone and shale." The rock unit was formalized into a Formation in 1963 by J. D. Glaeser. Glaeser re-mapped some areas previously mapped as the Gettysburg Formation to the Hammer Creek Formation. A major groundwate ...

Conglomerate (geology)
Conglomerate () is a clastic sedimentary rock that is composed of a substantial fraction of rounded to subangular gravel-size clasts. A conglomerate typically contains a matrix of finer-grained sediments, such as sand, silt, or clay, which fills the interstices between the clasts. The clasts and matrix are typically cemented by calcium carbonate, iron oxide, silica, or hardened clay. Conglomerates form by the consolidation and lithification of gravel. They can be found in sedimentary rock sequences of all ages but probably make up less than 1 percent by weight of all sedimentary rocks. In terms of origin and depositional mechanisms, they are closely related to sandstones and exhibit many of the same types of sedimentary structures, e.g., tabular and trough cross-bedding and graded bedding.Boggs, S. (2006) ''Principles of Sedimentology and Stratigraphy.'', 2nd ed. Prentice Hall, New York. 662 pp. Friedman, G.M. (2003) ''Classification of sediments and sedimentary rocks.'' In G ...

Triassic
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archo ...

Battle Of Carlisle
The Battle of Carlisle was an American Civil War skirmish fought in Pennsylvania on the same day as the Battle of Gettysburg, First Day. Stuart's Confederate cavalry briefly engaged Union militia under Maj. Gen. William F. "Baldy" Smith at Carlisle and set fire to the Carlisle Barracks. Stuart's cavalry withdrew and arrived at the Battle of Gettysburg, Second Day, to the annoyance and concern of Gen. Robert E. Lee. Background After Carlisle was settled in 1751, the Carlisle Barracks military post was established nearby in 1757 and had an antebellum United States Army Cavalry School (e.g., Captain Stoneman's four companies had a Civil War encampment at Horner's Mill on May 6, 1861.) By June 1863 the barrack's cavalry had been "withdrawn to Harrisburg". On June 27, 1863, Confederate Lt. Gen. Richard S. Ewell's Second Corps of the Army of Northern Virginia stopped at Carlisle en route to Harrisburg and requisitioned supplies, forage, and food from the populace. Ewell, ...

Battle Of Hanover
The Battle of Hanover took place on June 30, 1863, in Hanover in southwestern York County, Pennsylvania, as part of the Gettysburg Campaign of the American Civil War. Maj. Gen. J.E.B. Stuart's Confederate cavalry, which was riding north to get around the Union Army of the Potomac, attacked a Federal cavalry regiment, driving it through the streets of Hanover. Brig. Gen. Elon Farnsworth's brigade arrived and counterattacked, routing the Confederate vanguard and nearly capturing Stuart himself. Stuart soon counterattacked. Reinforced by Brig. Gen. George A. Custer's Michigan Brigade, Farnsworth held his ground, and a stalemate ensued. Stuart was forced to continue north and east to get around the Union cavalry, further delaying his attempt to rejoin Robert E. Lee's army, which was then concentrating at Cashtown Gap west of Gettysburg. Background As Robert E. Lee moved his Army of Northern Virginia northward in June 1863 through the Shenandoah Valley towards Pennsylvania, porti ...

Confederate States Army
The Confederate States Army, also called the Confederate Army or the Southern Army, was the military land force of the Confederate States of America (commonly referred to as the Confederacy) during the American Civil War (1861–1865), fighting against the United States forces to win the independence of the Southern states and uphold the institution of slavery. On February 28, 1861, the Provisional Confederate Congress established a provisional volunteer army and gave control over military operations and authority for mustering state forces and volunteers to the newly chosen Confederate president, Jefferson Davis. Davis was a graduate of the U.S. Military Academy, and colonel of a volunteer regiment during the Mexican–American War. He had also been a United States senator from Mississippi and U.S. Secretary of War under President Franklin Pierce. On March 1, 1861, on behalf of the Confederate government, Davis assumed control of the military situation at Charleston, South C ...

Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

American Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by states that had seceded. The central cause of the war was the dispute over whether slavery would be permitted to expand into the western territories, leading to more slave states, or be prevented from doing so, which was widely believed would place slavery on a course of ultimate extinction. Decades of political controversy over slavery were brought to a head by the victory in the 1860 U.S. presidential election of Abraham Lincoln, who opposed slavery's expansion into the west. An initial seven southern slave states responded to Lincoln's victory by seceding from the United States and, in 1861, forming the Confederacy. The Confederacy seized U.S. forts and other federal assets within their borders. Led by Confederate President Jefferson Davis, ...

Palatinate (region)
The Palatinate (german: Pfalz; Palatine German: ''Palz'') is a region of Germany. In the Middle Ages it was known as the Rhenish Palatinate (''Rheinpfalz'') and Lower Palatinate (''Unterpfalz''), which strictly speaking designated only the western part of the Electorate of the Palatinate (''Kurfürstentum Pfalz''), as opposed to the Upper Palatinate (''Oberpfalz''). It occupies roughly the southernmost quarter of the German federal state of Rhineland-Palatinate (''Rheinland-Pfalz''), covering an area of with about 1.4 million inhabitants. Its residents are known as Palatines (''Pfälzer''). Geography The Palatinate borders Saarland in the west, historically also comprising the state's Saarpfalz District. In the northwest, the Hunsrück mountain range forms the border with the Rhineland region. The eastern border with Hesse and the Baden region runs along the Upper Rhine river, while the left bank, with Mainz and Worms as well as the Selz basin around Alzey, belong to th ...
