The Pensacola Light is a lighthouse at Pensacola Bay , in Florida. It is the third iteration of what was originally a lightship , the Aurora Borealis, and remains an aid to navigation.
98-478: The first Pensacola Light was the lightship Aurora Borealis . It was moved to Pensacola in 1823 from its previous post at the mouth of the Mississippi River after a lighthouse had been completed there. Because of frequent rough seas, the lightship had to be anchored inside the bay entrance, behind Santa Rosa Island , and could not reliably be seen from ships outside the bay. In 1825 a 40-foot (12 m) tower
196-486: A federation , becoming a fully independent country over the next century. Over its history, Canada's international borders have changed several times as it has added territories and provinces, making it the world's second-largest country by area. The major difference between a Canadian province and a territory is that provinces receive their power and authority from the Constitution Act, 1867 (formerly called

Bermuda was consequently the most important British naval and military base in the Americas. Canadian confederation resulted in the Canadian Militia becoming responsible for the defence of the Maritimes, the abolition of the British Army's commander-in-chief there, and
392-665: A great deal of power relative to the federal government, with jurisdiction over many public goods such as health care, education, welfare, and intra-provincial transportation. They receive " transfer payments " from the federal government to pay for these, as well as exacting their own taxes. In practice, however, the federal government can use these transfer payments to influence these provincial areas. For instance, in order to receive healthcare funding under Medicare , provinces must agree to meet certain federal mandates, such as universal access to required medical treatment. Provincial and territorial legislatures have no second chamber like

Bermuda was consequently left out of the confederation of Canada, though it retained naval links with Halifax and the state church (or established church ), the Church of England , continued to place Bermuda under the bishop of Newfoundland until 1919 (Bermuda also remained linked to
784-478: A natural process known as avulsion or delta switching, the lower Mississippi River has shifted its final course to the mouth of the Gulf of Mexico every thousand years or so. This occurs because the deposits of silt and sediment begin to clog its channel, raising the river's level and causing it to eventually find a steeper, more direct route to the Gulf of Mexico. The abandoned distributaries diminish in volume and form what are known as bayous . This process has, over

It had a sixth order Fresnel lens , and showed a fixed white light visible for 11 miles (18 km). The Pensacola Bar Beacon was removed from service and demolished some time in the early 1900s. At the start of the Civil War , Pensacola was controlled by Confederate forces, while Fort Pickens across

Following Canada's participation in the Second World War , in a 1948 referendum , a narrow majority of Newfoundland citizens voted to join the Confederation, and on March 31, 1949, Newfoundland became Canada's tenth province. The province was officially renamed Newfoundland and Labrador in 2001. Bermuda ,

Its four largest provinces by area ( Quebec , Ontario , British Columbia and Alberta ) are also (with Quebec and Ontario switched in order) its most populous; together they account for 86% of the country's population. The territories (the Northwest Territories , Nunavut and Yukon ) account for over a third of Canada's area but are only home to 0.3% of its population, which skews
1666-868: Is controlled and managed as a series of pools created by 26 locks and dams. The Upper Mississippi River is joined by the Minnesota River at Fort Snelling in the Twin Cities ; the St. Croix River near Prescott, Wisconsin ; the Cannon River near Red Wing, Minnesota ; the Zumbro River at Wabasha, Minnesota ; the Black , La Crosse , and Root rivers in La Crosse, Wisconsin ; the Wisconsin River at Prairie du Chien, Wisconsin ;

The river served sometimes as a barrier, forming borders for New Spain , New France , and the early United States, and throughout as a vital transportation artery and communications link. In the 19th century, during the height of the ideology of manifest destiny , the Mississippi and several tributaries, most notably its largest,
7546-449: The new river channel, contiguous with the adjacent state. Also, due to a meander in the river, a small part of western Kentucky is contiguous with Tennessee but isolated from the rest of its state. Many of the communities along the Mississippi River are listed below; most have either historic significance or cultural lore connecting them to the river. They are sequenced from the source of the river to its end. The road crossing highest on
7644-704: The one minority provincial/territorial government is held by the Liberals in Yukon . They are in government with a formal confidence and supply agreement from the Yukon New Democratic Party . The Canadian National Vimy Memorial , near Vimy , Pas-de-Calais, and the Beaumont-Hamel Newfoundland Memorial , near Beaumont-Hamel , both in France, are ceremonially considered Canadian territory. In 1922,
7742-598: The past 5,000 years, caused the coastline of south Louisiana to advance toward the Gulf from 15 to 50 miles (24 to 80 km). The currently active delta lobe is called the Birdfoot Delta, after its shape, or the Balize Delta , after La Balize, Louisiana , the first French settlement at the mouth of the Mississippi. The current form of the Mississippi River basin was largely shaped by the Laurentide Ice Sheet of
7840-538: The plume did not mix with the surrounding sea water immediately. Instead, it stayed intact as it flowed through the Gulf of Mexico, into the Straits of Florida , and entered the Gulf Stream . The Mississippi River water rounded the tip of Florida and traveled up the southeast coast to the latitude of Georgia before finally mixing in so thoroughly with the ocean that it could no longer be detected by MODIS. Over geologic time,
7938-410: The province of Newfoundland, in 1949. In 1999, Nunavut was created from the eastern portion of the Northwest Territories. Yukon lies in the western portion of Northern Canada, while Nunavut is in the east. All three territories combined are the most sparsely populated region in Canada, covering 3,921,739 km (1,514,192 sq mi) in land area. They are often referred to as a single region,
8036-567: The reduction of British military forces in the Maritimes to a small garrison for the protection of the Halifax dockyard, which would be withdrawn when that dockyard was handed over to the Dominion government in 1905 for use by the new Canadian naval service. Britain retained control of Bermuda as an imperial fortress, with the governor and commander-in-chief of Bermuda (a military officer previously ranking between lieutenant-colonel and major-general) becoming
8134-479: The river, although the Mississippi defines part of the boundary of each of these states. In all of these cases, the middle of the riverbed at the time the borders were established was used as the line to define the borders between adjacent states. In various areas, the river has since shifted, but the state borders have not changed, still following the former bed of the Mississippi River as of their establishment, leaving several small isolated areas of one state across
8232-500: The same name. For example, no provincial Conservative or Progressive Conservative Party shares an organizational link to the federal Conservative Party of Canada , and neither do provincial Green Parties to the Green Party of Canada . Provincial New Democratic Parties, on the other hand, are fully integrated with the federal New Democratic Party —meaning that provincial parties effectively operate as sections, with common membership, of
8330-400: The site of the head of navigation of the river. The Upper Mississippi has a number of natural and artificial lakes, with its widest point being Lake Winnibigoshish , near Grand Rapids, Minnesota , over 11 miles (18 km) across. Lake Onalaska , created by Lock and Dam No. 7 , near La Crosse, Wisconsin , is more than 4 miles (6.4 km) wide. Lake Pepin , a natural lake formed behind
8428-514: The size of the North-West Territories. In 1898 the Yukon Territory, later renamed "Yukon" in 2003, was carved from the area surrounding the Klondike gold fields . On September 1, 1905, a portion of the North-West Territories south of the 60th parallel north became the provinces of Alberta and Saskatchewan. In 1912, the boundaries of Quebec, Ontario, and Manitoba were expanded northward: Manitoba's to
8526-524: The state line still follows the old channel. The town of Kaskaskia, Illinois once stood on a peninsula at the confluence of the Mississippi and Kaskaskia (Okaw) Rivers . Founded as a French colonial community, it later became the capital of the Illinois Territory and was the first state capital of Illinois until 1819. Beginning in 1844, successive flooding caused the Mississippi River to slowly encroach east. A major flood in 1881 caused it to overtake
8624-413: The territorial level. The King's representative in each province is the lieutenant governor . In each of the territories there is an analogous commissioner , but they represent the federal government rather than the monarch. Most provinces have rough provincial counterparts to major federal parties. However, these provincial parties are not usually formally linked to the federal parties that share
8722-603: The territories of Canada have no inherent sovereignty and have only those powers delegated to them by the federal government. They include all of mainland Canada north of latitude 60° north and west of Hudson Bay and all islands north of the Canadian mainland (from those in James Bay to the Queen Elizabeth Islands ). The following table lists the territories in order of precedence (each province has precedence over all
8820-744: The territories, regardless of the date each territory was created). Another territory, the District of Keewatin , existed from October 7, 1876, until September 1, 1905, when it rejoined the Northwest Territories and became the Keewatin Region . It occupied the area that is now the Kenora District of Ontario, northern Manitoba, and mainland Nunavut. The government of Keewatin was based in Winnipeg, Manitoba. The territory did not have any representation in federal parliament. The vast majority of Canada's population
8918-494: The two biggest provinces in Canada, with together over 60% of the population at any given time. The population of the West relative to Canada as a whole has steadily grown over time, while that of Atlantic Canada has declined. Ontario, Quebec, New Brunswick, and Nova Scotia were the original provinces, formed when several British North American colonies federated on July 1, 1867, into the Dominion of Canada and by stages began accruing
9016-567: The upper and lower river, the Mississippi is further controlled by thousands of wing dikes that moderate the river's flow in order to maintain an open navigation channel and prevent the river from eroding its banks. The head of navigation on the Mississippi is the St. Anthony Falls Lock. Before the Coon Rapids Dam in Coon Rapids, Minnesota , was built in 1913, steamboats could occasionally go upstream as far as Saint Cloud, Minnesota , depending on river conditions. The uppermost lock and dam on
9114-540: The winters until the 1820s, when Bermuda (which was better located to control the Atlantic Seaboard of the United States, impossible to attack over land, and almost impregnable against attack over water) became the main base year round. A large British Army garrison in Bermuda , which fell under the commander-in-chief in Nova Scotia , existed to defend the colony as a naval base (and to prevent it becoming as useful
9212-473: The world by volume. On average, the Mississippi has 8% the flow of the Amazon River , which moves nearly 7 million cubic feet per second (200,000 m /s) during wet seasons. Before 1900, the Mississippi River transported an estimated 440 million short tons (400 million metric tons) of sediment per year from the interior of the United States to coastal Louisiana and the Gulf of Mexico. During
9310-513: The world's tenth-largest river by discharge flow, and the largest in North America. Native Americans have lived along the Mississippi River and its tributaries for thousands of years. Many were hunter-gatherers , but some, such as the Mound Builders , formed prolific agricultural and urban civilizations, and some practiced aquaculture . The arrival of Europeans in the 16th century changed
9408-504: Was built on a 40-foot (12 m) bluff at the south entrance to Pensacola Bay . This light was also partially obscured by trees close to the tower and on Santa Rosa Island. In 1858 a new tower was built on the north side of the bay entrance, and was lit on January 1, 1859. The new, and current, tower is 150 feet (46 m) tall, and also sits on a 40-foot (12 m) bluff located on the Pensacola Naval Air Station , placing
9506-496: Was chosen to designate the "true head" of the Mississippi River as a combination of the last four letters of the Latin word for truth ( ver itas ) and the first two letters of the Latin word for head ( ca put ). However, the lake is in turn fed by a number of smaller streams. From its origin at Lake Itasca to St. Louis, Missouri , the waterway's flow is moderated by 43 dams. Fourteen of these dams are located above Minneapolis in
9604-537: Was placed in the tower in 1869. The tower was all white during the Civil War. Later, the upper two-thirds of the tower was painted black. Electricity was introduced to the lighthouse in 1939, eliminating the need to rewind the light rotation clockworks every 4½ hours. The light was automated in 1965. The lighthouse tower and associated buildings were placed on the National Register of Historic Places in 1974. In 1989,
