Sorber Run
Sorber Run is a tributary of Bowman Creek in Luzerne County and Wyoming County, in Pennsylvania, in the United States. It is approximately long and flows through Lake Township in Luzerne County and Noxen Township in Wyoming County. The watershed of the stream has an area of . The surficial geology in the stream's vicinity consists of alluvium and Wisconsinan Till. The watershed is designated as Exceptional Value waters and a Migratory Fishery. The stream is one of two Wilderness Trout Streams in Wyoming County. Course Sorber Run begins in a valley on a mountain in Lake Township, Luzerne County. It flows east-northeast for a few tenths of a mile before turning northeast for a short distance. The stream then turns north for several tenths of a mile, flowing through a valley to the west of Sorber Mountain. It then exits Lake Township, Luzerne County and enters Noxen Township, Wyoming County. In this reach, the stream turns north-northwest for some distance before turning north. A ...

Surficial Geology
Superficial deposits (or surficial deposits) refer to geological deposits typically of Quaternary age (less than 2.6 million years old). These geologically recent unconsolidated sediments may include stream channel and floodplain deposits, beach sands, talus gravels and glacial drift and moraine. All pre-Quaternary deposits are referred to as bedrock. Types and history There are several types of superficial deposit, including raised beaches and brickearth. These were formed in periods of climate change during the ice ages. The raised beaches were generally formed during periods of higher sea level, when ice sheets were at a minimum, and the sand and shingle deposits can be seen in many low cliffs. The brickearth is originally a wind-blown dust deposited under extremely cold, dry conditions but much has been re-deposited by flood water and mixed with flints. Superficial deposits were originally recorded only onshore and around the coast where they were laid down by various natu ...

Pennsylvania Bulletin
The ''Pennsylvania Bulletin'' is a weekly journal produced by the Commonwealth of Pennsylvania. Created on a weekly basis by staff in the Legislative Reference Bureau of Pennsylvania, which is housed at the Pennsylvania State Capitol building in Harrisburg, Pennsylvania, this publication serves as "the Commonwealth's official gazette for information and rulemaking" and is released for public consumption each Friday at 9 a.m. It lists the recent changes made to various agency rules and regulations within Pennsylvania's state government system and serves as a supplement to the ''Pennsylvania Code''. History In 1968, legislators of the Commonwealth of Pennsylvania realized that improvements needed to be made in the way changes to state laws were communicated to state employees and members of the general public. In response, they passed the Commonwealth Documents Law (CDL) (P.L. 769, No. 240) (45 P.S. §§ 1102–1208) on July 31, 1968, establishing the ''Pennsylvania Code'' and the ...

Class A Wild Trout Waters
Class A Wild Trout Waters are the highest biomass class given to streams in Pennsylvania by the Pennsylvania Fish and Boat Commission. They are considered to contain the highest-quality naturally reproducing trout populations in Pennsylvania. The first streams received their Class A Wild Trout Waters designations in 1983. There are now hundreds of such waters, comprising nearly of streams. Class A Wild Trout Waters receive certain legal protections. For instance, they are typically classified by the Pennsylvania Department of Environmental Protection as High-Quality Coldwater Fisheries. Most Class A Wild Trout Waters are subject to standard statewide angling regulations by the Pennsylvania Fish and Boat Commission. The official definition of Class A Wild Trout Waters is "streams that support a population of naturally produced trout of sufficient size and abundance to support a long-term and rewarding sport fishery". These streams are considered to be the best angling streams in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennsylvania Natural Heritage Program
Founded in 1982, the Pennsylvania Natural Heritage Program (PNHP) gathers and manages information regarding the status and location of the Commonwealth of Pennsylvania’s rare species and habitats and native natural communities. PHNP's goal is to build, maintain, and provide accurate and accessible ecological information needed for conservation, development planning and natural resource management. PNHP works with the Western Pennsylvania Conservancy, Pennsylvania Department of Conservation and Natural Resources (DCNR), the Pennsylvania Fish and Boat Commission, and the Pennsylvania Game Commission. One important initiative within the Heritage Program is the County Natural Heritage Inventory, which conducts county-wide inventories of threatened and endangered species as well as important natural areas. At present, completed county inventories are available for 57 counties and the remaining 10 are in progress. In addition, PNHP will return to counties and perform updates to ensu ...

Quadrangle (geography)
A "quadrangle" is a topographic map produced by the United States Geological Survey (USGS) covering the United States. The maps are usually named after local physiographic features. The shorthand "quad" is also used, especially with the name of the map; for example, "the Ranger Creek, Texas quad". From approximately 1947-1992, the USGS produced the 7.5 minute series, with each map covering an area one-quarter of the older 15-minute quad series, which it replaced. A 7.5 minute quadrangle map covers an area of . Both map series were produced via photogrammetric analysis of aerial photography using stereoplotters supplemented by field surveys. These maps employ the 1927 North American Datum (NAD27); conversion or a change in settings is necessary when using a GPS which by default employ the WGS84 geodetic datum. Beginning in 2009, the USGS made available digital versions of 7.5 minute quadrangle maps based on GIS data that use the NAD83 datum, which is typically within one meter of ...

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] |
Glacial Lake Bowman
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. The Holocene is the current interglacial. A time with no glaciers on Earth is considered a greenhouse climate state. Quaternary Period Within the Quaternary, which started about 2.6 million years before present, there have been a number of glacials and interglacials. At least eight glacial cycles have occurred in the last 740,000 years alone. Penultimate Glacial Period The Penultimate Glacial Period (PGP) is the glacial period that occurred before the Last Glacial Period. It began about 194,000 years ago and ended 135,000 years ago, with the beginning of the Eemian interglacial. Last Glacial Period The last glacial period was the most recent glacial period wi ...

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#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, 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.
