Sidneys Knob
Sidneys Knob appears to be an atypical mountain for Pennsylvania when viewed from the northeast. Most of the mountains in the Commonwealth are long linear ridges or flatted topped plateau mountains. Sidneys Knob is part of a bifurcated ridgeline as seen in the topographic map below.''Burnt Cabins, PA'', 7.5 Minute USGS Topographic Quadrangle, 1984 ed. The mountain is seen on postcards, mainly viewed from the Pennsylvania Turnpike, as vehicles exit west out of the Tuscarora Mountain Tunnel Tuscarora Mountain Tunnel is one of four original Pennsylvania Turnpike tunnels still in active use. A second tube was bored in the late 1960s to ease traffic conditions. The Tuscarora Mountain tunnels measure in length and are the second-long ... northeast of the peak. Sometimes referred to as "Pyramid Point" or on early postcards as Henry's Knob, this landmark is one of the most noted on the turnpike.

Appalachian Mountains
The Appalachian Mountains, often called the Appalachians, are a mountain range in eastern to northeastern North America. The term "Appalachian" refers to several different regions associated with the mountain range, and its surrounding terrain. The general definition used is one followed by the United States Geological Survey and the Geological Survey of Canada to describe the respective countries' Physiographic region, physiographic regions. The U.S. uses the term Appalachian Highlands and Canada uses the term Appalachian Uplands; the Appalachian Mountains are not synonymous with the Appalachian Plateau, which is one of the provinces of the Appalachian Highlands. The Appalachian range runs from the Newfoundland (island), Island of Newfoundland in Canada, southwestward to Central Alabama in the United States; south of Newfoundland, it crosses the 96-square-mile (248.6 km2) archipelago of Saint Pierre and Miquelon, an overseas collectivity of France, meaning it is technica ...

United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on its hundredth anniversary, was "Earth Science in the Pub ...

Mountain
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 above the surrounding land. A few mountains are inselberg, isolated summits, but most occur in mountain ranges. mountain formation, Mountains are formed through tectonic plate, 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 hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commonwealth (U
A commonwealth is a traditional English term for a political community founded for the common good. The noun "commonwealth", meaning "public welfare, general good or advantage", dates from the 15th century. Originally a phrase (the common-wealth or the common wealth – echoed in the modern synonym "public wealth"), it comes from the old meaning of "wealth", which is "well-being", and was deemed analogous to the Latin ''res publica''. The term literally meant "common well-being". In the 17th century, the definition of "commonwealth" expanded from its original sense of "public welfare" or "wikt:commonweal, commonweal" to mean "a state in which the supreme power is vested in the people; a republic or democracy, democratic state". The term evolved to become a title to a number of political entities. Three countries – Australia, the Bahamas, and Dominica – have the official title "Commonwealth", as do four U.S. states and two Territories of the United States, U.S. territories. Sin ...

Plateau
In geology and physical geography, a plateau (; ; : plateaus or plateaux), also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side. Often one or more sides have deep hills or escarpments. Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers. Plateaus are classified according to their surrounding environment as intermontane, piedmont, or continental. A few plateaus may have a small flat top while others have wider ones. Formation Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, plate tectonics movements, and erosion by water and glaciers. Volcanic Volcanic plateaus are produced by volcanic activity. They may be formed by upwelling of volcanic magma or extrusion of lava. The underlining mechanism in forming p ...

Pennsylvania Turnpike
The Pennsylvania Turnpike, sometimes shortened to Penna Turnpike or PA Turnpike, is a controlled-access toll road which is operated by the Pennsylvania Turnpike Commission (PTC) in Pennsylvania. It runs for across the southern part of the state, connecting Pittsburgh, Harrisburg and Philadelphia, and passes through four tunnels as it crosses the Appalachian Mountains. A component of the Interstate Highway System, it is part of Interstate 76 (I-76) between the Ohio state line and Valley Forge ( I-70 runs concurrently with I-76 between New Stanton and Breezewood), Interstate 276 (I-276) between Valley Forge and Bristol Township, and I-95 from Bristol Township to the New Jersey state line. The turnpike's western terminus is at the Ohio state line in Lawrence County, where it continues west as the Ohio Turnpike. The eastern terminus is the New Jersey state line at the Delaware River–Turnpike Toll Bridge, which crosses the Delaware River in Bucks County. It c ...

Tuscarora Mountain Tunnel
Tuscarora Mountain Tunnel is one of four original Pennsylvania Turnpike tunnels still in active use. A second tube was bored in the late 1960s to ease traffic conditions. The Tuscarora Mountain tunnels measure in length and are the second-longest active tunnels on the Pennsylvania Turnpike system. The Sideling Hill Tunnel is the longest overall, but was abandoned in 1968. Allegheny Mountain Tunnel The Allegheny Mountain Tunnel is a vehicular tunnel carrying the Pennsylvania Turnpike through the Allegheny Mountains. At this point, the Turnpike carries Interstates 70 and 76. When the tunnel was built, it was considered an "engineering m ... is the longest in active use.
