Moraine State Park
Moraine State Park is a Pennsylvania state park on in Brady, Clay, Franklin, Muddy Creek, and Worth townships in Butler County, Pennsylvania, in the United States. The park's main feature is its man-made lake, Lake Arthur, formed by impounding Muddy Creek, which is and is used for recreational purposes. The surrounding park is used for hiking, bicycling, group camping, picnicking, and hunting. Moraine State Park hosts the annual Regatta at Lake Arthur in August. The park was the location of the 1973 and 1977 National Scout Jamborees. Moraine State Park is at the intersection of Interstate 79 and U.S. Route 422 and shares a border with Jennings Environmental Education Center to the north. Moraine State Park was chosen by the Pennsylvania Department of Conservation and Natural Resources (DCNR) and its Bureau of State Parks as one of "25 Must-See Pennsylvania State Parks". History Moraine State Park is named for the glacial moraines that cover its land. The moraines were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butler County, Pennsylvania
Butler County is a county in the Commonwealth of Pennsylvania. It is part of Western Pennsylvania. As of the 2020 census, the population was 193,763. Its county seat is Butler. Butler County was created on March 12, 1800, from part of Allegheny County and named in honor of General Richard Butler, a hero of the American Revolution. Butler County is part of the Pittsburgh, PA Metropolitan Statistical Area. History Some famous inventions and discoveries were made in Butler County. Saxonburg was founded as a Prussian colony by John A. Roebling, a civil engineer, and his brother Carl. After farming for a time, Roebling returned to engineering, and invented his revolutionary "wire rope.", which he first produced at Saxonburg. He moved the operation to Trenton, New Jersey. He is best known for designing his most famous work, the Brooklyn Bridge, but designed and built numerous bridges in Pittsburgh and other cities as well.

Bituminous Coal
Bituminous coal, or black coal, is a type of coal containing a tar-like substance called bitumen or asphalt. Its coloration can be black or sometimes dark brown; often there are well-defined bands of bright and dull material within the seams. It is typically hard but friable. Its quality is ranked higher than lignite and sub-bituminous coal, but lesser than anthracite. It is the most abundant rank of coal, with deposits found around the world, often in rocks of Carboniferous age. Bituminous coal is formed from sub-bituminous coal that is buried deeply enough to be heated to or higher. Bituminous coal is used primarily for electrical power generation and in the steel industry. Bituminous coal suitable for smelting iron (''coking coal'' or ''metallurgical coal'' ) must be low in sulfur and phosphorus. It commands a higher price than other grades of bituminous coal (thermal coal) used for heating and power generation. Within the coal mining industry, this type of coal is known ...

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 ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacial Till
image:Geschiebemergel.JPG, Closeup of glacial till. Note that the larger grains (pebbles and gravel) in the till are completely surrounded by the matrix of finer material (silt and sand), and this characteristic, known as ''matrix support'', is diagnostic of till. image:Glacial till exposed in roadcut-750px.jpg, Glacial till with tufts of grass Till or glacial till is unsorted glacier, glacial sediment. Till is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines. Till is classified into primary deposits, laid down directly by glaciers, and secondary deposits, reworked by fluvial transport and other processes. Description Till is a form of '' glacial drift'', which is rock material transported by a glacier and deposited directly from the ice or from running water emerging from the ice. It is distinguished from other forms of drift in that it is depos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Farmer
A farmer is a person engaged in agriculture, raising living organisms for food or raw materials. The term usually applies to people who do some combination of raising field crops, orchards, vineyards, poultry, or other livestock. A farmer might own the farm land or might work as a laborer on land owned by others. In most developed economies, a "farmer" is usually a farm owner (landowner), while employees of the farm are known as ''farm workers'' (or farmhands). However, in other older definitions a farmer was a person who promotes or improves the growth of plants, land or crops or raises animals (as livestock or fish) by labor and attention. Over half a billion farmers are smallholders, most of whom are in developing countries, and who economically support almost two billion people. Globally, women constitute more than 40% of agricultural employees. History Farming dates back as far as the Neolithic, being one of the defining characteristics of that era. By the Bronze Age, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

North Country Trail
The North Country National Scenic Trail, generally known as the North Country Trail or simply the NCT, is a footpath stretching over from Middlebury in central Vermont to Lake Sakakawea State Park in central North Dakota in the United States; connecting both the Long Trail and the Appalachian Trail with the Lewis and Clark Trail. Passing through the eight states of Vermont, New York, Pennsylvania, Ohio, Michigan, Wisconsin, Minnesota and North Dakota, it is the longest of the eleven National Scenic Trails authorized by Congress. As of early 2019, 3,129 miles (5,036 km) of the trail is in place. The NCT is administered by the National Park Service, managed by federal, state, and local agencies, and built and maintained primarily by the volunteers of the North Country Trail Association (NCTA) and its partners. The 28 chapters of the NCTA, its 3,200+ members and each affiliate organization have assumed responsibility for trail construction and maintenance of a specific secti ...

Beaver Wars
The Beaver Wars ( moh, Tsianì kayonkwere), also known as the Iroquois Wars or the French and Iroquois Wars (french: Guerres franco-iroquoises) were a series of conflicts fought intermittently during the 17th century in North America throughout the Saint Lawrence River valley in Canada and the lower Great Lakes region which pitted the Iroquois against the Hurons, northern Algonquians and their French allies. As a result of this conflict, the Iroquois destroyed several confederacies and tribes through warfare: the Hurons or Wendat, Erie, Neutral, Wenro, Tionontate, Susquehannock, Mahican and northern Algonquins whom they defeated and dispersed, some fleeing to neighboring peoples and others assimilated, routed, or killed. The Iroquois sought to expand their territory and to monopolize the fur trade with European markets. They originally were a confederacy of the Mohawk, Oneida, Onondaga, Cayuga, and Seneca tribes inhabiting the lands in what is now Upstate New York along the sh ...

Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4). Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clay is the oldest known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been dated to around 14,000 BC, and clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sand
Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass. The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz. Calcium carbonate is the second most common type of sand, for example, aragonite, which has mostly been created, over the past 500million years, by various forms of life, like coral and shellfish. For example, it is the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years like the Caribbean. Somewhat more rarely, sand may be composed of calciu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
