Maryland
–
The states largest city is Baltimore, and its capital is Annapolis. Among its occasional nicknames are Old Line State, the Free State, the state is named after Henrietta Maria of France, the wife of Charles I of England. George Calvert was the first Lord of Baltimore and the first English proprietor of the colonial grant. Maryland was the state to ratify the United States Constitution. Maryland is one of the smallest U. S. states in terms of area, as well as one of the most densely populated, Maryland has an area of 12,406.68 square miles and is comparable in overall area with Belgium. It is the 42nd largest and 9th smallest state and is closest in size to the state of Hawaii, the next largest state, its neighbor West Virginia, is almost twice the size of Maryland. Maryland possesses a variety of topography within its borders, contributing to its nickname America in Miniature. The mid-portion of this border is interrupted by Washington, D. C. which sits on land that was part of Montgomery and Prince Georges counties and including the town of Georgetown. This land was ceded to the United States Federal Government in 1790 to form the District of Columbia, the Chesapeake Bay nearly bisects the state and the counties east of the bay are known collectively as the Eastern Shore. Close to the town of Hancock, in western Maryland, about two-thirds of the way across the state. This geographical curiosity makes Maryland the narrowest state, bordered by the Mason–Dixon line to the north, portions of Maryland are included in various official and unofficial geographic regions. Much of the Baltimore–Washington corridor lies just south of the Piedmont in the Coastal Plain, earthquakes in Maryland are infrequent and small due to the states distance from seismic/earthquake zones. The M5.8 Virginia earthquake in 2011 was felt moderately throughout Maryland, buildings in the state are not well-designed for earthquakes and can suffer damage easily. The lack of any glacial history accounts for the scarcity of Marylands natural lakes, laurel Oxbow Lake is an over one-hundred-year-old 55-acre natural lake two miles north of Maryland City and adjacent to Russett. Chews Lake is a natural lake two miles south-southeast of Upper Marlboro. There are numerous lakes, the largest of them being the Deep Creek Lake. Maryland has shale formations containing natural gas, where fracking is theoretically possible, as is typical of states on the East Coast, Marylands plant life is abundant and healthy. Middle Atlantic coastal forests, typical of the southeastern Atlantic coastal plain, grow around Chesapeake Bay, moving west, a mixture of Northeastern coastal forests and Southeastern mixed forests cover the central part of the state

Potomac River
–
The Potomac River /pəˈtoʊmək/ is located along the mid-Atlantic Ocean coast of the United States and flows into the Chesapeake Bay. The river is approximately 405 miles long, with an area of about 14,700 square miles. In terms of area, this makes the Potomac River the fourth largest river along the Atlantic coast of the United States, over 5 million people live within the Potomac watershed. The river forms part of the borders between Maryland and Washington, D. C. on the left descending bank and West Virginia and Virginia on the right descending bank. The majority of the lower Potomac River is part of the State of Maryland, exceptions include a small tidal portion within the District of Columbia, and the border with Virginia being delineated from point to point. Except for a portion of its headwaters in West Virginia. The South Branch Potomac River lies completely within the state of West Virginia except for its headwaters, the Potomac River runs 405 miles from the Fairfax Stone in West Virginia on the Allegheny Plateau to Point Lookout, Maryland, and drains 14,679 square miles. The length of the river from the junction of its North and South Branches to Point Lookout is 302 miles, the average flow is 10,800 ft³/s. The largest flow recorded on the Potomac at Washington, D. C. was in March 1936 when it reached 425,000 ft³/s. The lowest flow recorded at the same location was 600 ft³/s in September,1966. The source of the North Branch is at the Fairfax Stone located at the junction of Grant, Tucker, the source of the South Branch is located near Hightown in northern Highland County, Virginia. The rivers two branches converge just east of Green Spring in Hampshire County, West Virginia, to form the Potomac. Once the Potomac drops from the Piedmont to the Coastal Plain at Little Falls, tides further influence the river as it passes through Washington, D. C. salinity in the Potomac River Estuary increases thereafter with distance downstream. The estuary also widens, reaching 11 statute miles wide at its mouth, Potomac is a European spelling of Patowmeck, the Algonquian name of a Native American village, perhaps meaning something brought. Native Americans had different names for different parts of the river, calling the river above Great Falls Cohongarooton, meaning honking geese and Patawomke below the fall, meaning river of swans. The spelling of the name has many forms over the years from Patawomeke to Patawomeck, Patowmack. The rivers name was decided upon as Potomac by the Board on Geographic Names in 1931. The river itself is at least two years old, likely extending back ten to twenty million years before present when the Atlantic Ocean lowered and exposed coastal sediments along the fall line

Rock Creek Park
–
Rock Creek Park is a large urban park that bisects the Northwest quadrant of Washington, D. C. The park was created by an Act of Congress in 1890, the Old Stone House in Georgetown, and certain of the Fort Circle Parks, a series of batteries and forts encircling the District of Columbia for its defense during the U. S. Civil War. Rock Creek Park was established by an act of Congress signed into law by President Benjamin Harrison on September 27,1890, glover and other civic leaders and in the wake of the creation of the National Zoo the preceding year. It was only the national park established by the U. S. following Yellowstone in 1872. Sequoia was created at the time, and Yosemite shortly thereafter. In 1933, Rock Creek Park became part of the newly formed National Capital Parks unit of the National Park Service, Rock Creek Park is the oldest natural urban park in the National Park System. In 1913, Congress authorized creation of the Rock Creek and Potomac Parkway, the parkway is a major traffic thoroughfare, especially along the portion south of the zoo. The park is patrolled by the United States Park Police, the main section of the park comprises 1754 acres, along the Rock Creek Valley. Including the other areas the park administers, it encompasses more than 2000 acres. The parklands follow the course of Rock Creek across the D. C. -Maryland border to connect with Rock Creek Stream Valley Park, the Maryland parks are operated by the Maryland-National Capital Park and Planning Commission. The Rock Creek Historic District was listed on the National Register of Historic Places on October 23,1991, Rock Creek Park also maintains cultural exhibits, including the Peirce Mill. Rock Creek is a venue for jogging, cycling, and inline skating, especially on the long, winding Beach Drive. A number of the citys outstanding bridges, such as the Lauzuns Legion, Dumbarton, Taft, in 2014 it was named best obscure memorial by Washington City Paper. Rock Creek Park Horse Center, founded in 1972, is located in the middle of the park near the Nature Center, the barn, run by Guest Services Inc, has 57 stalls, two outdoor rings, one indoor ring, and three bluestone turnout paddocks. The stable provides trail rides, pony rides, and lessons for the public, the stable primarily teaches English riding, with an emphasis on lower-level jumping and dressage. The barn is home to Rock Creek Riders, a therapeutic riding program for adults. Past participants in the program include brain injured veterans of the conflicts in Iraq and Afghanistan and people with autism, cerebral palsy, the program is volunteer-run and relies on donations and contributions for funding. The horse centers summer camps are popular with DC residents, the stable offers summer camp from 9-3 for children over eight, and a two-hour afternoon camp for children between five and eight years old

Tributary
–
A tributary or affluent is a stream or river that flows into a larger stream or main stem river or a lake. A tributary does not flow directly into a sea or ocean, tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. A confluence, where two or more bodies of water together, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from, distributaries are most often found in river deltas. Right tributary and left tributary are terms stating the orientation of the relative to the flow of the main stem river. These terms are defined from the perspective of looking downstream, where tributaries have the same name as the river into which they feed, they are called forks. These are typically designated by compass direction, for example, the American River receives flow from its North, Middle, and South forks. The Chicago Rivers North Branch has the East, West, and Middle Fork, the South Branch has its South Fork, forks are sometimes designated as right or left. Here, the handedness is from the point of view of an observer facing upstream, for instance, Steer Creek has a left tributary which is called Right Fork Steer Creek. Tributaries are sometimes listed starting with those nearest to the source of the river, the Strahler Stream Order examines the arrangement of tributaries in a hierarchy of first, second, third, and higher orders, with the first-order tributary being typically the least in size. For example, a second-order tributary would be the result of two or more first-order tributaries combining to form the second-order tributary, another method is to list tributaries from mouth to source, in the form of a tree structure, stored as a tree data structure

Atlantic Ocean
–
The Atlantic Ocean is the second largest of the worlds oceans with a total area of about 106,460,000 square kilometres. It covers approximately 20 percent of the Earths surface and about 29 percent of its surface area. It separates the Old World from the New World, the Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Eurasia and Africa to the east, and the Americas to the west. The Equatorial Counter Current subdivides it into the North Atlantic Ocean, in contrast, the term Atlantic originally referred specifically to the Atlas Mountains in Morocco and the sea off the Strait of Gibraltar and the North African coast. The Greek word thalassa has been reused by scientists for the huge Panthalassa ocean that surrounded the supercontinent Pangaea hundreds of years ago. The term Aethiopian Ocean, derived from Ancient Ethiopia, was applied to the Southern Atlantic as late as the mid-19th century, many Irish or British people refer to the United States and Canada as across the pond, and vice versa. The Black Atlantic refers to the role of ocean in shaping black peoples history. Irish migration to the US is meant when the term The Green Atlantic is used, the term Red Atlantic has been used in reference to the Marxian concept of an Atlantic working class, as well as to the Atlantic experience of indigenous Americans. Correspondingly, the extent and number of oceans and seas varies, the Atlantic Ocean is bounded on the west by North and South America. It connects to the Arctic Ocean through the Denmark Strait, Greenland Sea, Norwegian Sea, to the east, the boundaries of the ocean proper are Europe, the Strait of Gibraltar and Africa. In the southeast, the Atlantic merges into the Indian Ocean, the 20° East meridian, running south from Cape Agulhas to Antarctica defines its border. In the 1953 definition it extends south to Antarctica, while in later maps it is bounded at the 60° parallel by the Southern Ocean, the Atlantic has irregular coasts indented by numerous bays, gulfs, and seas. Including these marginal seas the coast line of the Atlantic measures 111,866 km compared to 135,663 km for the Pacific. Including its marginal seas, the Atlantic covers an area of 106,460,000 km2 or 23. 5% of the ocean and has a volume of 310,410,900 km3 or 23. 3%. Excluding its marginal seas, the Atlantic covers 81,760,000 km2 and has a volume of 305,811,900 km3, the North Atlantic covers 41,490,000 km2 and the South Atlantic 40,270,000 km2. The average depth is 3,646 m and the maximum depth, the bathymetry of the Atlantic is dominated by a submarine mountain range called the Mid-Atlantic Ridge. It runs from 87°N or 300 km south of the North Pole to the subantarctic Bouvet Island at 42°S, the MAR divides the Atlantic longitudinally into two halves, in each of which a series of basins are delimited by secondary, transverse ridges. The MAR reaches above 2000 m along most of its length, the MAR is a barrier for bottom water, but at these two transform faults deep water currents can pass from one side to the other

Chesapeake Bay
–
It is the largest estuary in North America. With its northern portion in Maryland and the part in Virginia. More than 150 major rivers and streams flow into the bays 64, 299-square-mile drainage basin, the bay is approximately 200 miles long from its northern headwaters in the Susquehanna River to its outlet in the Atlantic Ocean. It is 2.8 miles wide at its narrowest and 30 miles at its widest, total shoreline including tributaries is 11,684 miles, circumnavigating a surface area of 4,479 square miles. Average depth is 21 feet, reaching a maximum of 174 feet, the bay is spanned twice, in Maryland by the Chesapeake Bay Bridge from Sandy Point to Kent Island and in Virginia by the Chesapeake Bay Bridge-Tunnel connecting Virginia Beach to Cape Charles. Known for both its beauty and bounty, the bay became emptier, with crabs, oysters. Recent restoration efforts begun in the 1990s have been ongoing and show potential for growth of the oyster population. The health of the Chesapeake Bay improved in 2015, marking three years of gains over the past four years, according to a new report by the University of Maryland, the word Chesepiooc is an Algonquian word referring to a village at a big river. It is the seventh oldest surviving English place-name in the U. S. first applied as Chesepiook by explorers heading north from the Roanoke Colony into a Chesapeake tributary in 1585 or 1586. The name may refer to the Chesepian or Chesapeake people. They occupied an area which is now the Norfolk, Portsmouth, Chesapeake, in 2005, Algonquian linguist Blair Rudes helped to dispel one of the areas most widely held beliefs, that Chesapeake means something like great shellfish bay. The name might actually have meant something like great water, or it might have just referred to a location at the bays mouth. In addition, the name is almost always prefixed by the in usage by local residents, The Chesapeake, The Chesapeake Bay, the Chesapeake Bay is an estuary to the North Atlantic, lying between the Delmarva Peninsula to the east and the North American mainland to the west. It is the ria, or drowned valley, of the Susquehanna River and it is not a fjord, because the Laurentide Ice Sheet never reached as far south as the northernmost point on the bay. The large rivers entering the bay from the west have broad mouths and are extensions of the ria for miles up the course of each river. The bay was formed starting about 10,000 years ago when rising sea levels at the end of the last ice age flooded the Susquehanna River valley. Parts of the bay, especially the Calvert County, Maryland and these cliffs, generally known as Calvert Cliffs, are famous for their fossils, especially fossilized shark teeth which are commonly found washed up on the beaches next to the cliffs. Scientists Cliffs is a community in Calvert County named for the desire to create a retreat for scientists when the community was founded in 1935

Stream
–
A stream is a body of water with a current, confined within a bed and banks. Streams are important as conduits in the cycle, instruments in groundwater recharge. The biological habitat in the vicinity of a stream is called a riparian zone. Given the status of the ongoing Holocene extinction, streams play an important corridor role in connecting fragmented habitats, the study of streams and waterways in general is known as surface hydrology and is a core element of environmental geography. Brook A stream smaller than a creek, especially one that is fed by a spring or seep and it is usually small and easily forded. A brook is characterised by its shallowness and its bed being composed primarily of rocks, creek In North America, Australia and New Zealand, a small to medium-sized natural stream. Sometimes navigable by motor craft and may be intermittent, in parts of Maryland, New England, the UK and India, a tidal inlet, typically in a salt marsh or mangrove swamp, or between enclosed and drained former salt marshes or swamps. In these cases, the stream is the stream, the course of the seawater through the creek channel at low. River A large natural stream, which may be a waterway, runnel the linear channel between the parallel ridges or bars on a shoreline beach or river floodplain, or between a bar and the shore. Tributary A contributory stream, or a stream which does not reach the sea, sometimes also called a branch or fork. There are a number of names for a stream. Allt is used in Highland Scotland, beck is used in Yorkshire, Lancashire, Dumfriesshire, Cumbria, Norfolk, and Lincolnshire. Bourne or winterbourne is used in the chalk downland of southern England, brook is used in the Midlands, Lancashire and Cheshire. Burn is used in Scotland and North East England, gill or ghyll is seen in the north of England and other areas influenced by Old Norse. Rivulet is an term encountered in Victorian era publications, stream is used in Southern England. Syke is used in lowland Scotland and Cumbria for a seasonal stream, branch is used to name streams in Maryland and Virginia. Falls is also used to name streams in Maryland, for streams/rivers which have waterfalls on them, little Gunpowder Falls and The Jones Falls are actually rivers named in this manner, unique to Maryland. Kill in New York, Pennsylvania, Delaware, and New Jersey comes from a Dutch language word meaning riverbed or water channel, run in Ohio, Maryland, Michigan, New Jersey, Pennsylvania, Virginia, or West Virginia can be the name of a stream
8.
Tide
–
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of the Earth. Some shorelines experience a semi-diurnal tide—two nearly equal high and low tides each day, other locations experience a diurnal tide—only one high and low tide each day. A mixed tide—two uneven tides a day, or one high, Tides vary on timescales ranging from hours to years due to a number of factors. To make accurate records, tide gauges at fixed stations measure water level over time, gauges ignore variations caused by waves with periods shorter than minutes. These data are compared to the level usually called mean sea level. Tidal phenomena are not limited to the oceans, but can occur in other systems whenever a gravitational field varies in time. For example, the part of the Earth is affected by tides. Tide changes proceed via the following stages, Sea level rises over several hours, covering the intertidal zone, the water rises to its highest level, reaching high tide. Sea level falls over several hours, revealing the intertidal zone, the water stops falling, reaching low tide. Oscillating currents produced by tides are known as tidal streams, the moment that the tidal current ceases is called slack water or slack tide. The tide then reverses direction and is said to be turning, slack water usually occurs near high water and low water. But there are locations where the moments of slack tide differ significantly from those of high, Tides are commonly semi-diurnal, or diurnal. The two high waters on a day are typically not the same height, these are the higher high water. Similarly, the two low waters each day are the low water and the lower low water. The daily inequality is not consistent and is small when the Moon is over the equator. From the highest level to the lowest, Highest Astronomical Tide – The highest tide which can be predicted to occur, note that meteorological conditions may add extra height to the HAT. Mean High Water Springs – The average of the two high tides on the days of spring tides, mean High Water Neaps – The average of the two high tides on the days of neap tides. Mean Sea Level – This is the sea level

Georgetown (Washington, D.C.)
–
Georgetown is a historic neighborhood, commercial, and entertainment district located in northwest Washington, D. C. situated along the Potomac River. Founded in 1751 in the Province of Maryland, the port of Georgetown predated the establishment of the federal district, Georgetown remained a separate municipality until 1871, when the United States Congress created a new consolidated government for the whole District of Columbia. A separate act passed in 1895 specifically repealed Georgetowns remaining local ordinances, Georgetown is home to the main campus of Georgetown University and numerous other landmarks, such as the Volta Bureau and the Old Stone House, the oldest unchanged building in Washington. The embassies of Cameroon, France, Kosovo, Iceland, Liechtenstein, Mongolia, Sweden, Thailand, Ukraine, situated on the fall line, Georgetown was the farthest point upstream that oceangoing boats could navigate the Potomac River. In 1632, English fur trader Henry Fleet documented a Native American village of the Nacotchtank people called Tohoga on the site of present-day Georgetown, the area was then part of the Province of Maryland, an English colony. George Gordon constructed a tobacco inspection house along the Potomac in approximately 1745, the site was already a tobacco trading post when the inspection house was built. Warehouses, wharves, and other buildings were constructed around the inspection house. It did not take long before Georgetown grew into a port, facilitating trade. In 1751, the legislature of the Province of Maryland authorized the purchase of 60 acres of land from Gordon, a survey of the town was completed in February 1752. Since Georgetown was founded during the reign of George II of Great Britain, another theory is that the town was named after its founders, George Gordon and George Beall. The Maryland Legislature formally issued a charter and incorporated the town in 1789, robert Peter, an early area merchant in the tobacco trade, became Georgetowns first mayor in 1790. Col. John Beatty established the first church in Georgetown, a Lutheran church on High Street, Stephen Bloomer Balch established a Presbyterian Church in 1784. In 1795, the Trinity Catholic Church was built, along with a parish school-house, construction of St. Johns Episcopal Church began in 1797, but paused for financial reasons until 1803, and the church was finally consecrated in 1809. Banks in Georgetown included the Farmers and Mechanics Bank, which was established in 1814, other banks included the Bank of Washington, Patriotic Bank, Bank of the Metropolis, and the Union and Central Banks of Georgetown. Newspapers in Georgetown included the Republican Weekly Ledger, which was the first paper, the Sentinel was first published in 1796 by Green, English & Co. Charles C. Fulton began publishing the Potomac Advocate, which was started by Thomas Turner. Other newspapers in Georgetown included the Georgetown Courier and the Federal Republican, magruder, the first postmaster, was appointed on February 16,1790, and in 1795, a custom house was established on Water Street. General James M. Lingan served as the first collector of the port, in the 1790s, City Tavern, the Union Tavern, and the Columbian Inn opened and were popular throughout the 19th century. Of these taverns, only the City Tavern remains today, as a social club located near the corner of Wisconsin Avenue

Watergate complex
–
The Watergate complex is a group of five buildings in the Foggy Bottom neighborhood of Washington, D. C. in the United States. Covering a total of 10 acres next to the John F, the complex has been sold several times since the 1980s. In the 1990s, it was split up and its component buildings, the investigation into the burglary revealed that high officials in the Nixon administration had ordered the break-in and then tried to cover up their involvement. The ensuing Watergate scandal, named for the complex, led to Nixons resignation on August 9,1974, the name Watergate and the suffix -gate have since become synonymous with political scandals in the United States and elsewhere. The Watergate superblock is bounded on the north by Virginia Avenue, on the east by New Hampshire Avenue, on the south by F Street and it is in the Foggy Bottom neighborhood overlooking the Potomac River, next to the Kennedy Center and the embassy of Saudi Arabia. The nearest Metro station,0.4 miles distant, is Foggy Bottom-GWU, Gas production ceased at the site in 1947, and the plant was demolished shortly thereafter. C. The name Watergate relates to numerous aspects of its physical and historical context, the complex sits near the eastern terminus of the Chesapeake and Ohio Canal, which operated from 1831 to 1924 and is now a National Historical Park. A large wooden water gate marks the point where the canal meets the Potomac River, land once owned by the canal company was part of the 10-acre site purchased in 1960 by the projects developer, Rome-based Società Generale Immobiliare. Another namesake is the restaurant, the Water Gate Inn. Instead, beginning in 1935, the steps faced a floating stage on the Potomac River on which open-air concerts were held. Up to 12,000 people would sit on the steps and surrounding grass and listen to symphonies, military bands, the music venue was depicted in scenes in the motion pictures Houseboat and Born Yesterday. The barge concerts ended in 1965 when jet service began at National Airport. The Watergate complex was developed by the Italian firm SGI, the company purchased the 10 acres that belonged to the defunct Chesapeake and Ohio Canal in February 1960 for $10 million. The project was announced on October 21,1960, Italian Luigi Moretti of the University of Rome was the chief architect, and Milton Fischer of the D. C. -based firm of Corning, Moore, Elmore and Fischer the associate architect. The apartment buildings included two-story units on the first and second floors, the design for the entire complex also envisioned an electronic security system so extensive that the press claimed intruders will have difficulty getting onto the grounds undetected. Boris V. Timchenko, a noted D. C, landscape features such as planters would also be used to create privacy barriers between apartments. The complex was the first mixed-use development in the District of Columbia, the Watergate complex was intended to be a city within a city, and provide so many amenities that residents would not need to leave. At the time, it was also the largest renewal effort in the District of Columbia undertaken solely with private funds, the Watergates curved structures were designed to emulate two nearby elements
