Haycock Mountain
Haycock Mountain or known as Ghost Mountain is a locally prominent hill with the highest summit in Bucks County. It rises above Nockamixon State Park, in the Delaware River drainage of southeastern Pennsylvania. Early settlers named it simply for its "resemblance to a cock of hay."Quoted at from Haycock is covered with numerous triassic diabase boulders, and is a bouldering destination with many established routes ranging from V0 to V10+. To the north northwest of the main peak is a secondary peak of approximately sometimes known as 'Little Haycock', and the main peak overlooks Lake Nockamixon to the southeast. Contained within the Tohickon Creek watershed, Haycock Mountain is drained by Dimple Creek to the west and Haycock Creek to the east. Since it lies within State Game Land Number 157, Haycock is used seasonally for hunting. * Geology Haycock Mountain was formed 200 million years ago by an intrusion of magma into local shale and argillite within the Newark Basin. ...

Tohickon Creek
Tohickon Creek is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed April 1, 2011 tributary of the Delaware River. Located entirely in Bucks County, in southeastern Pennsylvania, it rises in Springfield Township and has its confluence with the Delaware at Point Pleasant. It is dammed to form Lake Nockamixon. History Prior to European settlement, the area through which the creek runs was inhabited by the Lenape tribe. The area was called ''Tachan Hoking'' (pronounced Toc-ahn Hok Ing) or “Piece of Wood Area Place.” It could also mean ''Achtuhhu Ing'' (pronounced "Awk-too-who Ing") or "Deers Place." Early white settlers in the area noted the fast, constant current of the creek, and by the late eighteenth century a number of water-powered mills had sprung up along the lower portion of the Tohickon valley.MacReynolds, George, ''Place Names in Bucks County, Pennsylvania'', Doylestown, Bucks County Historical Society, D ...

Igneous Intrusions
Igneous rock (derived from the Latin word ''ignis'' meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Solidification into rock occurs either below the surface as intrusive rocks or on the surface as extrusive rocks. Igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form natural glasses. Igneous rocks occur in a wide range of geological settings: shields, platforms, orogens, basins, large igneous provinces, extended crust and oceanic crust. Geological significance Igneous and metamorphic rocks make up 90–95% of the top ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mountains Of Pennsylvania
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 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 isolated summits, but most occur in mountain ranges. Mountains are formed through 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, ecosystems of mountains: different elevations have different plants and ...

Climbing Areas Of The United States
Climbing is the activity of using one's hands, feet, or any other part of the body to ascend a steep topographical object that can range from the world's tallest mountains (e.g. the eight thousanders), to small boulders. Climbing is done for locomotion, sporting recreation, and for competition, and is also done in trades that rely on ascension; such as emergency rescue and military operations. Climbing is done indoors and outdoors and on natural (e.g. rock and ice) and artificial surfaces. Professional mountain guides or rock climbing guides (e.g. the UIAGM), were a significant element in developing the popularity of the sport in the natural environment, and remain so today. Since the 1980s, the development of competition climbing and the availability of artificial climbing walls have dramatically increased the popularity of rock climbing as a sport and led to the emergence of professional rock climbers, such as Wolfgang Güllich, Chris Sharma, Lynn Hill and Catherine ...

Hornfels
Hornfels is the group name for a set of contact metamorphic rocks that have been baked and hardened by the heat of intrusive igneous masses and have been rendered massive, hard, splintery, and in some cases exceedingly tough and durable. These properties are due to fine grained non-aligned crystals with platy or prismatic habits, characteristic of metamorphism at high temperature but without accompanying deformation. The term is derived from the German word ''Hornfels'', meaning "hornstone", because of its exceptional toughness and texture both reminiscent of animal horns. These rocks were referred to by miners in northern England as whetstones. Most hornfels are fine-grained, and while the original rocks (such as sandstone, shale, slate and limestone) may have been more or less fissile owing to the presence of bedding or cleavage planes, this structure is effaced or rendered inoperative in the hornfels. Though many hornfels show vestiges of the original bedding, they break acro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newark Basin
The Newark Basin is a sediment-filled rift basin located mainly in northern New Jersey but also stretching into south-eastern Pennsylvania and southern New York. It is part of the system of Eastern North America Rift Basins. Geology Approximately 220 million years ago, during the late Triassic Period, the supercontinent Pangaea began to break apart. The focus of the rifting began somewhere between where present-day eastern North America and north-western Africa were joined. As in all rifting environments, grabens formed. Many of these grabens were created, but for some of them, extension stopped before full rifting occurred. Where only partial rifting occurred, basins formed, analogous to the present-day Basin and Range Province in western United States. By definition, a basin is any area that collects sediments. These "aborted rifts" (rifts that are tectonically inactive and no longer collecting sediments) extend from North Carolina to Newfoundland. Along certain basins, riftin ...

Argillite
:''"Argillite" may also refer to Argillite, Kentucky.'' Argillite () is a fine-grained sedimentary rock composed predominantly of indurated clay particles. Argillaceous rocks are basically lithified muds and oozes. They contain variable amounts of silt-sized particles. The argillites grade into shale when the fissile layering typical of shale is developed. Another name for poorly lithified argillites is ''mudstone''. These rocks, although variable in composition, are typically high in aluminium and silica with variable alkali and alkaline earth cations. The term ''pelitic'' or ''pelite'' is often applied to these sediments and rocks. Metamorphism of argillites produces slate, phyllite, and pelitic schist. Belt Supergroup The Belt Supergroup, an assemblage of rocks of late Precambrian (Mesoproterozoic) age, includes thick sequences of argillite, as well as other metamorphosed or semi-metamorphosed mudstones.Schieber, J. 1990.

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 ...

Pennsylvania Game Commission
The Pennsylvania Game Commission (PGC) is the state agency responsible for wildlife conservation and management in Pennsylvania in the United States. It was originally founded years ago and currently utilizes more than 700 full-time employees and thousands of part-time and volunteers in its official mission to "manage and protect wildlife and their habitats while promoting hunting and trapping for current and future generations." History In the late 1800s as a result of deforestation, pollution and unregulated hunting/trapping, wildlife decreased in population and diversity. The wildlife, then-commonly referred to as "game," was to be protected by establishing the Game Commission in 1895 by state Legislature. It was—and still is—funded primarily through the sale of licenses, State Game Land natural resource revenue, and a federal excise tax on guns and ammunition.

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 ...
