Archbald Pothole State Park
Archbald Pothole State Park is a Pennsylvania state park in Archbald, Lackawanna County, Pennsylvania. The focal point of the park is Archbald Pothole. The pothole is a remnant of the Wisconsin Glacial Period, deep with a largest diameter of by . It has drawn tourists since just after it was discovered in 1884. Archbald Pothole State Park is on U.S. Route 6 Business in the borough of Archbald. History A coal miner, Patrick Mahon, discovered Archbald Pothole in 1884. Mahon was extending a mine shaft. When he set off a blast of explosives, water and stones came pouring into the mine shaft. He and the other miners fled the scene fearing for their lives. The manager of the mining company, Edward Jones, came to investigate. Jones ordered that the area be cleared of the fallen debris. Almost 1,000 tons of small rounded stones were removed and Jones soon realized that the vertical tunnel discovered by the coal miners was a large pothole. After serving as a ventilation ...

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 bedding ...

Seven Tubs Natural Area
Seven Tubs Recreation Area is a publicly accessible recreation area located in Luzerne County, Pennsylvania, and owned by the Pennsylvania Department of Conservation and Natural Resources. Continuously flowing glacial meltwater gouged a line of smooth tubs in gritty sandstone over 12,000 years ago. The tubs are potholes formed by the flowing water. The site is part of a recreation area in the Pennsylvania mountains about south of downtown Wilkes-Barre.Litchman , Lori. "Seven Tubs Natural Area, Luzerne County." Greentreks Network. 2006. 19 Mar 2008 . The site is popular among hikers for its easy accessibility and beginner-level hiking environment. Geology The glaciers of the Ice Age were instrumental in shaping the physical features of the natural world that we see today. They too are responsible for the formations of the tubs. As ice melts over long periods of time, its eroding capabilities become much more substantial. Glacial melting produced large volumes of flowing water ...

Moraine
A moraine is any accumulation of unconsolidated debris ( regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines ( till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Pr ...

Pocono Mountains
The Pocono Mountains, commonly referred to as the Poconos , are a geographical, geological, and cultural region in Northeastern Pennsylvania. They overlook the Delaware River and Delaware Water Gap to the east, Lake Wallenpaupack to the north, Wyoming Valley and the Coal Region to the west, and the Lehigh Valley to the south. The name Pocono is derived from the Munsee word Pokawachne, which means "Creek Between Two Hills". Much of the Poconos region lies within the Greater New York–Newark, NY–NJ–CT–PA Combined Statistical Area. The wooded hills and valleys have long been a popular recreation area, accessible within a two-hour drive to millions of metropolitan area residents, with many Pocono communities having resort hotels with fishing, hunting, skiing, and other sports facilities. The Poconos are an upland of the larger Allegheny Plateau, forming a escarpment. Population The Pocono Mountains are a popular recreational destination for local and regional visito ...

Geographic Names Information System
The Geographic Names Information System (GNIS) is a database of name and locative information about more than two million physical and cultural features throughout the United States and its territories, Antarctica, and the associated states of the Marshall Islands, Federated States of Micronesia, and Palau. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names. Data were collected in two phases. Although a third phase was considered, which would have handled name changes where local usages differed from maps, it was never begun. The database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recorded. Each feature receives ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wisconsin Glaciation
The Wisconsin Glacial Episode, also called the Wisconsin glaciation, was the most recent glacial period of the North American ice sheet complex. This advance included the Cordilleran Ice Sheet, which nucleated in the northern North American Cordillera; the Innuitian ice sheet, which extended across the Canadian Arctic Archipelago; the Greenland ice sheet; and the massive Laurentide Ice Sheet, which covered the high latitudes of central and eastern North America. This advance was synchronous with global glaciation during the last glacial period, including the North American alpine glacier advance, known as the Pinedale glaciation. The Wisconsin glaciation extended from approximately 75,000 to 11,000 years ago, between the Sangamonian Stage and the current interglacial, the Holocene. The maximum ice extent occurred approximately 25,000–21,000 years ago during the last glacial maximum, also known as the ''Late Wisconsin'' in North America. This glaciation radically altered the ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand. Between latitudes 35°N and 35°S, glaciers occur o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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.
