Prince William County, Virginia
Prince William County is located on the Potomac River in the U.S. state of Virginia. As of the 2020 census, the population sits at 482,204, making it Virginia's second-most populous county. Its county seat is the independent city of Manassas. A part of Northern Virginia, Prince William County is part of the Washington metropolitan area. In 2019 it had the 20th-highest income of any county in the United States. History At the time of European colonization, the native tribes of the area that would become Prince William County were the Doeg, an Algonquian-speaking sub-group of the Powhatan tribal confederation. When John Smith and other English explorers ventured to the upper Potomac River beginning in 1608, they recorded the name of a village the Doeg inhabited as ''Pemacocack'' (meaning "plenty of fish" in their language). It was located on the west bank of the Potomac River about 30 miles south of present-day Alexandria. Unable to deal with European diseases and firepow ...

Lunar Tide
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude (or "tidal range"). The predictions are influenced by many factors including the alignment of the Sun and Moon, the phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see '' Timing''). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude tides a day—is a third regular category. Tides va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northwestern Lake
Condit Hydroelectric Project was a development on the White Salmon River in the U.S. state of Washington. It was completed in 1913 to provide electrical power for local industry, and is listed in the National Register of Historic Places as an engineering and architecture landmark. PacifiCorp decommissioned the project due to rising environmental costs, and the dam was intentionally breached on October 26, 2011. The facility consisted of Condit Dam in Klickitat County, and its impoundment, Northwestern Lake; a woodstave pipeline that transported water to a surge tank and auxiliary spillway; two penstocks; and the powerhouse. Two horizontally mounted Francis turbines and generators produced electrical power, and the exhausted water rejoined the river about a mile downstream of the dam. The original design had fish ladders, which were twice destroyed by floods shortly after the dam's completion. The Washington State Fisheries Department then required Northwestern Electric to part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Michigan
Lake Michigan is one of the five Great Lakes of North America. It is the second-largest of the Great Lakes by volume () and the third-largest by surface area (), after Lake Superior and Lake Huron. To the east, its basin is conjoined with that of Lake Huron through the wide, deep, Straits of Mackinac, giving it the same surface elevation as its easterly counterpart; the two are technically a single lake. Lake Michigan is the world's largest lake by area in one country. Located in the United States, it is shared, from west to east, by the states of Wisconsin, Illinois, Indiana, and Michigan. Ports along its shores include Milwaukee and the City of Green Bay in Wisconsin; Chicago in Illinois; Gary in Indiana; and Muskegon in Michigan. Green Bay is a large bay in its northwest, and Grand Traverse Bay is in the northeast. The word "Michigan" is believed to come from the Ojibwe word (''michi-gami'' or ''mishigami'') meaning "great water". History Some of most studied ea ...

Treaty Of Guadalupe Hidalgo
The Treaty of Guadalupe Hidalgo ( es, Tratado de Guadalupe Hidalgo), officially the Treaty of Peace, Friendship, Limits, and Settlement between the United States of America and the United Mexican States, is the peace treaty that was signed on 2 February 1848, in the Villa de Guadalupe Hidalgo (now a neighborhood of Mexico City) between the United States and Mexico that ended the Mexican–American War (1846–1848). The treaty was ratified by the United States on 10 March and by Mexico on 19 May. The ratifications were exchanged on 30 May, and the treaty was proclaimed on 4 July 1848. With the defeat of its army and the fall of its capital in September 1847, Mexico entered into negotiations with the U.S. peace envoy, Nicholas Trist, to end the war. On the Mexican side, there were factions that did not concede defeat or seek to engage in negotiations. The treaty called for the United States to pay US$15 million to Mexico and to pay off the claims of American citizens against Mex ...

United States And Mexican Boundary Survey
The United States and Mexican Boundary Survey (1848–1855) determined the border between the United States and Mexico as defined in the Treaty of Guadalupe Hidalgo, which had ended the Mexican–American War. The results of the survey were published in the three volumes entitled Report on the United States and Mexican boundary survey, made under the direction of the secretary of the Interior by William H. Emory' (1857-1859). In addition to its documentation of the new boundary, the survey report was notable for its natural history content, including paleontology, botany, ichthyology, herpetology, ornithology, and mammalogy. The survey was also provided to the war department now known as the United States Department of War in order to provide data for building a railroad line. In the report's section titled, "Personal Accounts", a brief description of Panama is also included, along with the experiences he and his men had while conducting the survey, including the experiences of h ...

Canada–United States Border
The border between Canada and the United States is the longest international border in the world. The terrestrial boundary (including boundaries in the Great Lakes, Atlantic, and Pacific coasts) is long. The land border has two sections: Canada's border with the contiguous United States to its south, and with the U.S. state of Alaska to its west. The bi-national International Boundary Commission deals with matters relating to marking and maintaining the boundary, and the International Joint Commission deals with issues concerning boundary waters. The agencies currently responsible for facilitating legal passage through the international boundary are the Canada Border Services Agency (CBSA) and U.S. Customs and Border Protection (CBP). History 18th century The Treaty of Paris of 1783 ended the American Revolutionary War between Great Britain and the United States. In the second article of the Treaty, the parties agreed on all boundaries of the United States, including, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
