East Branch Fishing Creek
East Branch Fishing Creek is a tributary of Fishing Creek in Columbia County and Sullivan County, Pennsylvania, in the United States. It is long. The stream and its tributaries are acidic and contain aluminum. The area in the vicinity was first settled in the late 18th century. Course East Branch Fishing Creek primarily flows in a largely westward direction, from its source at State Game Lands #13, slightly west of Ricketts Glen State Park, to its mouth slightly north of Grassmere Park. The creek starts at the confluence of Sullivan Branch and Big Run. It starts flowing southwards for approximately one mile before picking up Heberly Run, its longest tributary. Further on, it receives Lead Run and turns southwest towards Jamison City. Shortly after the turn, the creek receives Trout Run, one of its shortest named tributaries. In Jamison City, the creek receives Blackberry Run and several unnamed tributaries before flowing into West Branch Fishing Creek. The total elevation c ...

Huntley Mountain Formation
The Huntley Mountain Formation is a late Devonian and early Mississippian mapped bedrock unit in Pennsylvania, in the United States. Description The formation is composed of relatively soft grayish-red shale and olive-gray sandstone. It is located in north central Pennsylvania. Haystacks The Haystacks are enigmatic mounds of sandstone that outcrop in Loyalsock Creek south of Dushore in Sullivan County. They are a single bed of quartz sandstone with an undulating upper surface with up to one meter relief. The origin of the mounds is debatable. Notable Exposures * The type section of the formation is at Huntley Mountain in Lycoming County, Pennsylvania, on the mountainside just north of the village of Waterville. * Base of the Loyalsock Creek gorge in Worlds End State Park * Haystacks beds, also in Loyalsock Creek Stratigraphy Geologist William E. Edmunds argues that the Huntley Mountain Formation is laterally equivalent to the Rockwell Formation (originally described in ...

Rivers Of Sullivan County, Pennsylvania
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, sprin ...

Aquatic Life
An aquatic ecosystem is an ecosystem formed by surrounding a body of water, in contrast to land-based terrestrial ecosystems. Aquatic ecosystems contain communities of organisms that are dependent on each other and on their environment. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. Freshwater ecosystems may be lentic (slow moving water, including pools, ponds, and lakes); lotic (faster moving water, for example streams and rivers); and wetlands (areas where the soil is saturated or inundated for at least part of the time). Types Marine ecosystems Marine coastal ecosystem Marine surface ecosystem Freshwater ecosystems Lentic ecosystem (lakes) Lotic ecosystem (rivers) Wetlands Functions Aquatic ecosystems perform many important environmental functions. For example, they recycle nutrients, purify water, attenuate floods, recharge ground water and provide habitats for wildlife. Aquatic ecosystems are also used for ...

Tram Road
Tramways are lightly laid railways, sometimes with the wagons or carriages moved without locomotives. Because individual tramway infrastructure is not intended to carry the weight of typical standard-gauge railway equipment, the tramways over which they operate may be built from less substantial materials. Tramways can exist in many forms; sometimes just tracks temporarily placed on the ground to transport materials around a factory, mine or quarry. Many, if not most, use narrow-gauge railway technology. The trains can be manually pushed by hand, pulled by animals (especially horses and mules), cable hauled by a stationary engine, or use small, light locomotives. The term is not in use in North America but in common use in the United Kingdom, and elsewhere, where British Railway terminology and practices had large influences on management practices, terminology, and railway cultures such as Australia, New Zealand, and those parts of Asia that consulted with British experts whe ...

Four-wheel Drive
Four-wheel drive, also called 4×4 ("four by four") or 4WD, refers to a two-axled vehicle drivetrain capable of providing torque to all of its wheels simultaneously. It may be full-time or on-demand, and is typically linked via a transfer case providing an additional output drive shaft and, in many instances, additional gear ranges. A four-wheel drive vehicle with torque supplied to both axles is described as "all-wheel drive" (AWD). However, "four-wheel drive" typically refers to a set of specific components and functions, and intended off-road application, which generally complies with modern use of the terminology. Definitions Four-wheel-drive systems were developed in many different markets and used in many different vehicle platforms. There is no universally accepted set of terminology that describes the various architectures and functions. The terms used by various manufacturers often reflect marketing rather than engineering considerations or significant technical diff ...

Waterfall
A waterfall is a point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling on to softer rock, which Erosion, erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls for years, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research. Definition and terminology A waterfall is gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennsylvania State Game Lands
The Pennsylvania State Game Lands (SGL) are lands managed by the Pennsylvania Game Commission (PGC) for hunting, trapping, and fishing. These lands, often not usable for farming or development, are donated to the PGC or purchased by the PGC with hunting license monies. The Pennsylvania Game Commission runs a monthly publication called the ''Pennsylvania Game News''. This publication features financial and legislative updates from the PGC, stories, and monthly Field Notes submitted by the Wildlife Conservation Officers of the Pennsylvania Game Commission. History Wild game animals have been hunted for thousands of years in what is now Pennsylvania, first by the Indigenous peoples of the Americas, later by Europeans. By 1890 game had practically disappeared from Pennsylvania. That year, John M. Phillips and other sportsmen, recognizing the scarcity of game, formed the Pennsylvania Sportsmen's Association so that they could press the state government for protection of wildlife. This ...

Acid
In computer science, ACID ( atomicity, consistency, isolation, durability) is a set of properties of database transactions intended to guarantee data validity despite errors, power failures, and other mishaps. In the context of databases, a sequence of database operations that satisfies the ACID properties (which can be perceived as a single logical operation on the data) is called a ''transaction''. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction. In 1983, Andreas Reuter and Theo Härder coined the acronym ''ACID'', building on earlier work by Jim Gray who named atomicity, consistency, and durability, but not isolation, when characterizing the transaction concept. These four properties are the major guarantees of the transaction paradigm, which has influenced many aspects of development in database systems. According to Gray and Reuter, the IBM Informa ...

Outcropping
An outcrop or rocky outcrop is a visible exposure of bedrock or ancient superficial deposits on the surface of the Earth. Features Outcrops do not cover the majority of the Earth's land surface because in most places the bedrock or superficial deposits are covered by soil and vegetation and cannot be seen or examined closely. However, in places where the overlying cover is removed through erosion or tectonic uplift, the rock may be exposed, or ''crop out''. Such exposure will happen most frequently in areas where erosion is rapid and exceeds the weathering rate such as on steep hillsides, mountain ridges and tops, river banks, and tectonic uplift, tectonically active areas. In Finland, Glacier, glacial erosion during the last glacial maximum (ca. 11000 BC), followed by scouring by sea waves, followed by Postglacial rebound, isostatic uplift has produced many smooth coastal and littoral outcrops. Bedrock and superficial deposits may also be exposed at the Earth's surface due to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
