Pleasant Valley, Bucks County, Pennsylvania
Pleasant Valley is an unincorporated community in Springfield Township, Bucks County, Pennsylvania, United States. History Prior to European settlement, the area was inhabited by the Lenape people. Its first name was Schuckenhausen, the name of the first church in this location constructed as a log building. In 1872, it was replaced by a stone church known as the Union Church, later becoming a dwelling. The oldest building is the Pleasant Valley Inn, now out of business. General Lafayette stopped at the inn on the way to a hospital in Bethlehem after being wounded in the Battle of Brandywine. The village was built upon two farms, one owned by Jacob Smith and the other John J. Ott. the name was changed to Pleasant Valley when the post office was established on September 15, 1828, by Lewis Ott, first postmaster.MacReynolds, George, ''Place Names in Bucks County, Pennsylvania'', Doylestown, Bucks County Historical Society, Doylestown, PA, 1942, P307.

List Of Sovereign States
The following is a list providing an overview of sovereign states around the world with information on their status and recognition of their sovereignty. The 206 listed states can be divided into three categories based on membership within the United Nations System: 193 UN member states, 2 UN General Assembly non-member observer states, and 11 other states. The ''sovereignty dispute'' column indicates states having undisputed sovereignty (188 states, of which there are 187 UN member states and 1 UN General Assembly non-member observer state), states having disputed sovereignty (16 states, of which there are 6 UN member states, 1 UN General Assembly non-member observer state, and 9 de facto states), and states having a special political status (2 states, both in free association with New Zealand). Compiling a list such as this can be a complicated and controversial process, as there is no definition that is binding on all the members of the community of nations concerni ...

Pennsylvania Route 212
Pennsylvania Route 212 (PA 212) is a state highway in Bucks County, Pennsylvania. The route runs from PA 313 in the borough of Quakertown northeast to PA 611 in Durham Township, just south of the borough of Riegelsville. The route, which is a two-lane undivided road its entire length, passes through rural areas of northern Bucks County, serving Richlandtown and Springtown. PA 212 has a concurrency with PA 412 through the Springtown area. The westernmost part of PA 212 between Quakertown and Richlandtown was part of the Richland Turnpike or Plank Road Company, a company established in 1854 to build a turnpike connecting present-day PA 313 and PA 412. PA 212 was first designated by 1927 to run from U.S. Route 309 (US 309, now PA 309) and PA 312 (now PA 663) in Quakertown northeast to US 611 (now PA 611) in Riegelsville. The easternmost part of PA 212 was completed by 1940. PA 313 was designated concurrent with PA 212 on Broad Street in Quakertown by the 1970s. By the ...

Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...

Siltstone
Siltstone, also known as aleurolite, is a clastic sedimentary rock that is composed mostly of silt. It is a form of mudrock with a low clay mineral content, which can be distinguished from shale by its lack of fissility.Blatt ''et al.'' 1980, pp.381-382 Although its permeability and porosity is relatively low, siltstone is sometimes a tight gas reservoir rock, an unconventional reservoir for natural gas that requires hydraulic fracturing for economic gas production. Siltstone was prized in ancient Egypt for manufacturing statuary and cosmetic palettes. The siltstone quarried at Wadi Hammamat was a hard, fine-grained siltstone that resisted flaking and was almost ideal for such uses. Description There is not complete agreement on the definition of siltstone. One definition is that siltstone is mudrock ( clastic sedimentary rock containing at least 50% clay and silt) in which at least 2/3 of the clay and silt fraction is composed of silt-sized particles. Silt is defined a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mudstone
Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from '' shale'' by its lack of fissility (parallel layering).Blatt, H., and R.J. Tracy, 1996, ''Petrology.'' New York, New York, W. H. Freeman, 2nd ed, 529 pp. The term ''mudstone'' is also used to describe carbonate rocks (limestone or dolomite) that are composed predominantly of carbonate mud. However, in most contexts, the term refers to siliciclastic mudstone, composed mostly of silicate minerals. The NASA Curiosity rover has found deposits of mudstone on Mars that contain organic substances such as propane, benzene and toluene. Definition There is not a single definition of mudstone that has gained general acceptance,Boggs 2006, p.143 though there is wide agreement that mudstones are fine-grained sedimentary rocks, composed mostly of silicate grains with a grain size less than . Individual grains this size are too small to be disting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Passaic Formation
The Passaic Formation is a mapped bedrock unit in Pennsylvania, New Jersey, and New York. It was previously known as the Brunswick Formation since it was first described in the vicinity of New Brunswick, New Jersey. It is now named for the city of Passaic, New Jersey, which is near where its type section was described by paleontologist Paul E. Olsen. Description The Passaic is defined as a reddish-brown shale, siltstone and mudstone with a few green and brown shale interbeds; red and dark-gray interbedded argillites near the base. In New Jersey, there are conglomerate and sandstone beds within the formation. Depositional environment The Passaic is mostly shallow lakes, playa, and alluvial fan deposits resulting from the rifting of Pangea. The red color is often evidence that the sediments were deposited in arid conditions.Faill, R.T., (2004). The Birdsboro Basin. ''Pennsylvania Geology'' V. 34 n. 4. The Passaic Formation overlies the Lockatong Formation deep lake sediment cycles, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delaware River
The Delaware River is a major river in the Mid-Atlantic (United States), Mid-Atlantic region of the United States. From the meeting of its branches in Hancock (village), New York, Hancock, New York, the river flows for along the borders of New York (state), New York, Pennsylvania, New Jersey, and Delaware, before emptying into Delaware Bay. It is the longest free-flowing river in the Eastern United States. The river has been recognized by the National Wildlife Federation as one of the country's Great Waters. The river's drainage basin, watershed drains an area of and provides drinking water for 17 million people. The river has two branches that rise in the Catskill Mountains of New York: the West Branch Delaware River, West Branch at Mount Jefferson (New York), Mount Jefferson in Jefferson, New York, Jefferson, Schoharie County, New York, Schoharie County, and the East Branch Delaware River, East Branch at Grand Gorge, New York, Grand Gorge, Delaware County, New York, ...

Cooks Creek (Delaware River)
Cooks Creek (also known as Cook Creek, Durham Creek, Schooks Creek, Scookes Creek, Scooks Creek, Squooks Creek) is a tributary of the Delaware River in Bucks County, Pennsylvania, in the United States, rising in Springfield Township and passing through Durham Township before emptying into the Pennsylvania Canal (Delaware Division) and the Delaware. History Cooks Creek was thought by historian Edward Mathews to have been named after Arthur Cooke, a landowner in the area (though not a resident) in this part of the county before 1700, but, there is doubt about this. In a deed executed on 10 February 1727 between Samuel Powell, Jeremiah Langhorne, and others of Philadelphia for tracts of land in Durham Township, the stream was referred to as Scooks Creek and the modern name may have been derived from that. The Creek was a major source of power for the Durham Mill and Furnace and a water supply to the Canal. In the 1940s, the creek was the only creek in Bucks County in which brook tr ...
