The Great Appalachian Valley, also called The Great Valley or Great Valley Region, is one of the major landform features of eastern North America. It is a gigantic trough, including a chain of valley lowlands, and the central feature of the Appalachian Mountains system. The trough stretches about 1,200 miles (1,900 km) from Quebec in the north to Alabama in the south and has been an important north–south route of travel since prehistoric times.
The Little Conemaugh River is a tributary of the Conemaugh River, approximately 30 miles (48 km) long, in western Pennsylvania in the United States.
Swatara Creek is a 72-mile-long (116 km) tributary of the Susquehanna River in east-central Pennsylvania in the United States. It rises in the Appalachian Mountains in central Schuylkill County and passes through northwest Lebanon County before draining into the Susquehanna at Middletown in Dauphin County.
The Cumberland Valley is a northern constituent valley of the Great Appalachian Valley, within the Atlantic Seaboard watershed in Pennsylvania and Maryland. The Appalachian Trail crosses through the valley.
Blue Mountain, Blue Mountain Ridge, or the Blue Mountains of Pennsylvania is a ridge of the Appalachian Mountains in eastern Pennsylvania. Forming the southern and eastern edge of the Ridge-and-Valley Appalachians physiographic province in Pennsylvania, Blue Mountain extends 150 miles (240 km) from the Delaware Water Gap on the New Jersey border in the east to Big Gap in Franklin County in south-central Pennsylvania at its southwestern end.
Regions of Pennsylvania in the United States include:
The geography of Pennsylvania varies from sea level marine estuary to mountainous plateau. The state is known for its natural resources, ports, and the leading role it played in the nation's founding and history.
Black Creek is a long source tributary of Nescopeck Creek so part of the Susquehanna River drainage basin. It is also the second & longer stream of the same name recognized by the USGS GNIS system in Luzerne County, Pennsylvania, in the United States—compared to the Black Creek beyond the ridgeline of the drainage divide, so in the Lehigh River valley and Carbon County. The headwaters of both Black Creeks in Luzerne county are only a few miles apart, and both valleys were traversed by the Lausanne-Nescopeck Turnpike in the first half of the 19th-century.
The geography of New York varies widely across the state. Most of New York is dominated by farms, forests, rivers, mountains, and lakes. New York's Adirondack Park is larger than any U.S. National Park in the contiguous United States. Niagara Falls, on the Niagara River as it flows from Lake Erie to Lake Ontario, is a popular attraction. The Hudson River begins near Lake Tear of the Clouds and flows south through the eastern part of the state without draining lakes George or Champlain. Lake George empties at its north end into Lake Champlain, whose northern end extends into Canada, where it drains into the Richelieu River and then the St. Lawrence. Four of New York City's five boroughs are on the three islands at the mouth of the Hudson River: Manhattan Island, Staten Island, and Brooklyn and Queens on Long Island.
The Geology of Pennsylvania consists of six distinct physiographic provinces, three of which are subdivided into different sections. Each province has its own economic advantages and geologic hazards and plays an important role in shaping everyday life in the state. From the southeast corner to the northwest corner of the state, they include: the Atlantic Plain Province, the Piedmont Province, the New England Province, the Ridge and Valley Province, the Appalachain Province, and the Central Lowlands Province.
Clarks Knob is a summit in Franklin County, Pennsylvania. It is the highest point on Blue Mountain, the eastern front range of Pennsylvania's Ridge and Valley Appalachians region.
Pochuck Mountain is a ridge in the New York-New Jersey Highlands region of the Appalachian Mountains. Pochuck Mountain's summit and most of its peaks lie within Vernon Township, Sussex County, New Jersey, although the south-western portion of the ridge lies within Hardyston Township, and the north-eastern tip of the ridge extends over the New York state line into Orange County. The ridge marks the eastern edge of the Great Appalachian Valley, and it divides the watersheds of the Wallkill River and its tributary Pochuck Creek. The two rivers meet at Pochuck Neck, marking the terminus of the ridge.
The Minisink or Minisink Valley is a loosely defined geographic region of the Upper Delaware River valley in northwestern New Jersey, northeastern Pennsylvania and New York.
Pisgah Mountain, or Pisgah Ridge on older USGS maps, is a ridgeline running 12.5 miles (20.1 km) from Tamaqua to Jim Thorpe, Pennsylvania from the Little Schuylkill River water gap to the Lehigh River water gap.
Nesquehoning Mountain or Nesquehoning Ridge is a 15–17-mile-long (24–27 km) coal bearing ridge dividing the waters of Lehigh Valley to the north from the Schuylkill River valley and the several near parallel ridgelines of the Ridge-and-valley Appalachians barrier range all local members of which run generally WSW-ENE in the greater overall area.
Mountain Top yard or Penobscot yard is a rail yard in Mountain Top, Pennsylvania. It was built by the Lehigh Coal & Navigation Company (LC&N) in response to an 1837 bill authorizing a right of way and was established by 1840, at least as a construction camp for the Ashley Planes, in support of the construction of the Lehigh and Susquehanna Railroad trackage and operations to join the northern Anthracite Coal Region from barge loading docks along the Susquehanna in Pittston, in the Wyoming Valley, with the Lehigh Canal.
Mauch Chunk Ridge or Mauch Chunk Mountain is a historically important barrier ridgeline north of the Blue Mountain escarpment and 3rd parallel ridgeline south of the Nesquehoning Creek after Nesquehoning Mountain and Pisgah Ridge in the Ridge-and-Valley Appalachians of Northeastern Pennsylvania.
Haystack Mountain (Pennsylvania), is an otherwise non-descript 1871 ft peak forming the steep southwestern faces of the Solomon Gap mountain pass's saddle connecting and dividing the Wyoming Valley from the Lehigh Valley.
The gaps of the Allegheny, meaning gaps in the Allegheny Ridge in west-central Pennsylvania, is a series of escarpment eroding water gaps along the saddle between two higher barrier ridge-lines in the eastern face atop the Allegheny Ridge or Allegheny Front escarpment. The front extends south through Western Maryland and forms much of the border between Virginia and West Virginia, in part explaining the difference in cultures between those two post-Civil War states. While not totally impenetrable to daring and energetic travelers on foot, passing the front outside of the water gaps with even sure footed mules was nearly impossible without navigating terrain where climbing was necessary on slopes even burros would find extremely difficult.
Hazle Creek is an American tributary source stream of the Lehigh and Delaware Rivers in the Commonwealth of Pennsylvania in the United States.
