Minnesota River
The Minnesota River ( dak, Mnísota Wakpá) is a tributary of the Mississippi River, approximately 332 miles (534 km) long, in the U.S. state of Minnesota. It drains a watershed of in Minnesota and about in South Dakota and Iowa. It rises in southwestern Minnesota, in Big Stone Lake on the Minnesota–South Dakota border just south of the Laurentian Divide at the Traverse Gap portage. It flows southeast to Mankato, then turns northeast. It joins the Mississippi at Mendota south of the Twin Cities of Minneapolis and St. Paul, near the historic Fort Snelling. The valley is one of several distinct regions of Minnesota. The name Minnesota comes from the Dakota language phrase, "Mnisota Makoce" which is translated to "land where the waters reflect the sky", as a reference to the many lakes in Minnesota rather than the cloudiness of the actual river. At times, the native variant form "Minisota River" is used. For over a century prior to the organization of the Minnesota Territ ...

Mendota Bridge
The Mendota Bridge (full name Fort Snelling–Mendota Bridge), in the US state of Minnesota carries State Highway 55 (MN 55) and MN 62 over the Minnesota River between Fort Snelling and Mendota Heights. It is the final bridge over the Minnesota River before the Minnesota flows into the Mississippi River at the "Meeting of the waters" or "Mendota" in the Dakota language. Traffic on the north end of the bridge may turn onto the Fort Road Bridge ( MN 5) to cross the Mississippi River into Saint Paul, Minnesota. The skylines of both Minneapolis and Saint Paul can be seen simultaneously from the bridge. History The structure was designed by C.A.P. Turner and Walter H. Wheeler. Turner also designed the Aerial Lift Bridge in Duluth, Minnesota, and the Liberty Memorial Bridge between Bismarck and Mandan, North Dakota. The bridge is dedicated to the "Gopher Gunners", 151st Field Artillery who died in World War I. It has a length of and was the longest co ...

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Ice Age
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet. Earth is currently in the Quaternary glaciation. Individual pulses of cold climate within an ice age are termed ''glacial periods'' (or, alternatively, ''glacials, glaciations, glacial stages, stadials, stades'', or colloquially, ''ice ages''), and intermittent warm periods within an ice age are called '' interglacials'' or ''interstadials''. In glaciology, ''ice age'' implies the presence of extensive ice sheets in both northern and southern hemispheres. By this definition, Earth is currently in an interglacial period—the Holocene. The amount of anthropogenic greenhouse gases emitted into Earth's oceans and atmosphere is predicted to prevent the next glacial period for th ...

Glacial River Warren
Glacial River Warren, also known as River Warren, was a prehistoric river that drained Lake Agassiz in central North America between about 13,500 and 10,650 BP calibrated (11,700 and 9,400 14C uncalibrated) years ago. A part of the uppermost portion of the former river channel was designated a National Natural Landmark in 1966. Geological history Lake Agassiz was formed from the meltwaters of the Laurentide Ice Sheet during the Wisconsin glaciation of the last ice age. Agassiz was an enormous body of water, up to deep, and at various times covering areas totaling over . Blocked by an ice sheet to the north, the lake water rose until about 13,500 BP calibrated (11,700 14C uncalibrated) years ago when it overtopped the ''Big Stone Moraine'', a ridge of glacial drift left by the receding glacier, at the location of Browns Valley, Minnesota. The lake's outflow was catastrophic, and carved a gorge through the moraine wide and deep, which is now known as the Traverse Gap. The ...

Mitchell Map
The Mitchell Map is a map made by John Mitchell (1711–1768), which was reprinted several times during the second half of the 18th century. The map, formally titled ''A map of the British and French dominions in North America'' &c., was used as a primary map source during the Treaty of Paris for defining the boundaries of the newly independent United States. The map remained important for resolving border disputes between the United States and Canada as recently as the 1980s dispute over the Gulf of Maine fisheries. The Mitchell Map is the most comprehensive map of eastern North America made during the colonial era. Its size is about wide by high. John Mitchell's initiation as a map maker John Mitchell was not a professional geographer or map-maker. Son of a wealthy Virginian family in Lancaster County, on Virginia's Northern Neck, he had been educated at Edinburgh University, Scotland; this education included the first two years of the three-year medical program.

Dakota Language
Dakota (''Dakhótiyapi, Dakȟótiyapi''), also referred to as Dakhota, is a Siouan language spoken by the Dakota people of the Sioux tribes. Dakota is closely related to and mutually intelligible with the Lakota language. It is critically endangered, with only around 290 fluent speakers left out of an ethnic population of almost 20,000. Morphology Nouns Dakota, similar to many Native American languages, is a mainly polysynthetic language, meaning that different morphemes in the form of affixes can be combined to form a single word. Nouns in Dakota can be broken down into two classes, primitive and derivative. Primitive nouns are nouns whose origin cannot be deduced from any other word (for example ''make'' or earth, ''peta'' or fire, and ''ate'' or father), while derivative nouns are nouns that are formed in various ways from words of other grammatical categories. Primitive nouns stand on their own and are separate from other words. Derivative nouns, on the other hand, are forme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regions Of Minnesota
The U.S. State of Minnesota is the northernmost state outside Alaska; its isolated Northwest Angle in Lake of the Woods is the only part of the 48 contiguous states lying north of the 49th parallel north. Minnesota is in the U.S. region known as the Upper Midwest in interior North America. The state shares a Lake Superior water border with Michigan and Wisconsin on the northeast; the remainder of the eastern border is with Wisconsin. Iowa is to the south, North Dakota and South Dakota are to the west, and the Canadian provinces of Ontario and Manitoba are to the north. With , or approximately 2.26% of the United States, Minnesota is the 12th largest state. Geology and terrain Minnesota contains some of the oldest rocks found on earth, gneisses some 3.6 billion years old, or 80% as old as the planet. About 2.7 billion years ago, basaltic lava poured out of cracks in the floor of the primordial ocean; the remains of this volcanic created the Canadian Shield in northea ...

Fort Snelling
Fort Snelling is a former military fortification and National Historic Landmark in the U.S. state of Minnesota on the bluffs overlooking the confluence of the Minnesota and Mississippi Rivers. The military site was initially named Fort Saint Anthony, but it was renamed Fort Snelling once its construction was completed in 1825. Before the American Civil War, the U.S. Army supported slavery at the fort by allowing its soldiers to bring their personal enslaved people. These included African Americans Dred Scott and Harriet Robinson Scott, who lived at the fort in the 1830s. In the 1840s, the Scotts sued for their freedom, arguing that having lived in "free territory" made them free, leading to the landmark United States Supreme Court case ''Dred Scott v. Sandford''. Slavery ended at the fort just before Minnesota statehood in 1858. The fort served as the primary center for U.S. government forces during the Dakota War of 1862. It also was the site of the encampment where eastern Dako ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minneapolis
Minneapolis () is the largest city in Minnesota, United States, and the county seat of Hennepin County. The city is abundant in water, with thirteen lakes, wetlands, the Mississippi River, creeks and waterfalls. Minneapolis has its origins in timber and as the flour milling capital of the world. It occupies both banks of the Mississippi River and adjoins Saint Paul, the state capital of Minnesota. Prior to European settlement, the site of Minneapolis was inhabited by Dakota people. The settlement was founded along Saint Anthony Falls on a section of land north of Fort Snelling; its growth is attributed to its proximity to the fort and the falls providing power for industrial activity. , the city has an estimated 425,336 inhabitants. It is the most populous city in the state and the 46th-most-populous city in the United States. Minneapolis, Saint Paul and the surrounding area are collectively known as the Twin Cities. Minneapolis has one of the most extensive public par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minneapolis–Saint Paul
Minneapolis–Saint Paul is a metropolitan area in the Upper Midwestern United States centered around the confluence of the Mississippi, Minnesota and St. Croix rivers in the U.S. state of Minnesota. It is commonly known as the Twin Cities after the area's two largest cities, Minneapolis and Saint Paul. Minnesotans often refer to the two together (or the seven-county metro area collectively) simply as "the cities". It is Minnesota's economic, cultural, and political center. Minneapolis and Saint Paul are independent municipalities with defined borders. Minneapolis sits mostly on the west side of the Mississippi River on lake-covered terrain. Although most of the city is residential neighborhoods, it has a business-dominated downtown area with some historic industrial areas, the Mill District and the Warehouse District. Minneapolis also has a popular uptown area. Saint Paul, which sits mostly on the east side of the river, has quaint tree-lined neighborhoods, a vast collec ...

Traverse Gap
The Traverse Gap is an ancient river channel occupied by Lake Traverse, Big Stone Lake and the valley connecting them at Browns Valley, Minnesota. It is located on the border of the U.S. states of Minnesota and South Dakota. Traverse Gap has an unusual distinction for a valley: it is crossed by a continental divide, and in some floods water has flowed across that divide from one drainage basin to the other. Before the Anglo-American Convention of 1818 it marked the border between British territory in the north and U.S. – or earlier, French – territory in the south. Geological history The Traverse Gap was cut at the end of the last ice age. The Laurentide Ice Sheet decayed and receded as the Wisconsonian glaciation drew to a close, and Glacial Lake Agassiz formed from its meltwaters. Outlets to the north were blocked by the glacier, and the outlet to the south was dammed by the Big Stone Moraine which had been left by the retreat of the ice sheet. Lake Agassiz filled until ...
