Pennsylvania, officially the Commonwealth of Pennsylvania, is a state located in the northeastern, Great Lakes and Mid-Atlantic regions of the United States. The Appalachian Mountains run through its middle. The Commonwealth is bordered by Delaware to the southeast, Maryland to the south, West Virginia to the southwest, Ohio to the west, Lake Erie and the Canadian province of Ontario to the northwest, New York to the north, and New Jersey to the east.

Sinking Creek is a tributary of Penns Creek in Centre County, Pennsylvania, in the United States. It is approximately 19.8 miles (31.9 km) long and flows through Harris Township, Potter Township, and Gregg Township. The watershed of the creek has an area of 40.70 square miles (105.4 km²).

The historic Egg Hill Church is located at the southwestern end of the hill.

Egg Hill Church is a historic church located at Potter Township, Centre County, Pennsylvania. It was built in 1860, and is a one-story, banked building built of pine on a stone foundation. It measures 35 feet wide and 42 feet long. Regular services at the church were suspended in 1927. The church is located at the southwest end of Egg Hill.

Geology

The crest of Egg Hill is along the axis of a minor syncline, within the larger Nittany Anticlinorium. The bedrock along the axis is the Ordovician Bald Eagle Formation, which is mostly sandstone.^[3] The crest of the hill is over 1,900 feet (580 m) elevation.

In structural geology, a syncline is a fold with younger layers closer to the center of the structure. A synclinorium is a large syncline with superimposed smaller folds. Synclines are typically a downward fold (synform), termed a synformal syncline, but synclines that point upwards can be found when strata have been overturned and folded.

In structural geology, an anticline is a type of fold that is an arch-like shape and has its oldest beds at its core. A typical anticline is convex up in which the hinge or crest is the location where the curvature is greatest, and the limbs are the sides of the fold that dip away from the hinge. Anticlines can be recognized and differentiated from antiforms by a sequence of rock layers that become progressively older toward the center of the fold. Therefore, if age relationships between various rock strata are unknown, the term antiform should be used.

The Ordovician is a geologic period and system, the second of six periods of the Paleozoic Era. The Ordovician spans 41.2 million years from the end of the Cambrian Period 485.4 million years ago (Mya) to the start of the Silurian Period 443.8 Mya.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

Maryland Route 213 is a 68.25-mile (109.84 km) state highway located on the Eastern Shore of Maryland in the United States. The route runs from MD 662 in Wye Mills, Queen Anne's County north to the Pennsylvania border in Cecil County, where it continues into that state as Pennsylvania Route 841. The route, which is a two-lane undivided highway its entire length, passes through mostly rural areas as well as the communities of Centreville, Chestertown, Galena, Cecilton, Chesapeake City, and Elkton. MD 213 intersects many routes including U.S. Route 50 near Wye Mills, US 301 near Centreville, and US 40 in Elkton. It crosses over the Chesapeake & Delaware Canal in Chesapeake City on the Chesapeake City Bridge. MD 213 is designated by the state as the Chesapeake Country Scenic Byway between the southern terminus and Chesapeake City with the portion north of MD 18 in Centreville a National Scenic Byway. In addition, the route is also considered part of the Atlantic to Appalachians Scenic Byway between Chesapeake City and MD 273 in Fair Hill.

Penns Valley is an eroded anticlinal valley of the Pennsylvania ridge and valley geologic region of the Appalachian Mountain range. The valley is located in southern Centre County, Pennsylvania. Along with the Nittany Valley to the north and east, it is part of the larger Nittany Anticlinorium. It is bordered by Nittany Mountain to the north, the Seven Mountains range to the south, and connects to the larger Nittany Valley to the west. There are two smaller subordinate valleys typically associated with the greater valley; Georges Valley in the south, separated by Egg Hill, and Brush Valley in the north, separated by Brush Mountain.

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. They are: the Atlantic Coastal Plain Province, the Piedmont Province, the New England Province, the Ridge and Valley Province, the Appalachian Plateau Province, and the Central Lowlands Province.

Bosley Minn is one of two names – the other being Wincle Minn – given to a prominent hill in southeast Cheshire and in the southwestern corner of the Peak District National Park in northern England. The long axis of the Minn runs NNE–SSW and its broad summit, which reaches to 386 metres (1,266 ft) at its highest point, slopes away to the valley of the Shell Brook in the east and towards Bosley Reservoir in the west. It is the western aspect of the hill, facing Bosley which is known as Bosley Minn whilst the eastern side which faces the village of Wincle is referred to as Wincle Minn.
