Minnesota River Valley
The Minnesota River () 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 Territory in 1849, the nam ...

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 c ...

Tributary
A tributary, or an ''affluent'', is a stream or river that flows into a larger stream (''main stem'' or ''"parent"''), river, or a lake. A tributary does not flow directly into a sea or ocean. Tributaries, and the main stem river into which they flow, drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean, another river, or into an endorheic basin. The Irtysh is a chief tributary of the Ob (river), Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ice age called Quaternary glaciation. Individual pulses of cold climate within an ice age are termed '' glacial periods'' (''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, the term ''ice age'' is defined by the presence of extensive ice sheets in the northern and southern hemispheres. By this definition, the current Holocene epoch is an interglacial period of an ice age. The accumulation of anthropogenic greenhouse gases is projected to delay the next glacial period.

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. Th ...

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
The Dakota language ( or ), also referred to as Dakhóta, is a Siouan language spoken by the Dakota people of the Očhéthi Šakówiŋ, commonly known in English as the Sioux. Dakota is closely related to and mutually intelligible with the Lakota language. 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 or earth, or fire, and 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 formed by the addition of affixes to words in other grammatical categories. Verbs Verbs in Dakota can appro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 concentration camp where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 on the border of the U.S. states of Minnesota and South Dakota. Traverse Gap has an unusual distinction for a valley: it is transected 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. The glacier blocked outlets to the north, and the outlet to the south was dammed by the Big Stone Moraine, a terminal moraine left by the ice sheet's retreat. Lake Agassiz filled until it overtopped ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laurentian Divide
The Laurentian Divide also called the Northern Divide and locally the '' height of land'', is a continental divide in central North America that separates the Hudson Bay watershed to the north from the Gulf of Mexico watershed to the south and the Great Lakes- St. Lawrence watershed to the southeast. Water north of the divide flows to Hudson Bay; water south of the divide and also south of the St. Lawrence Divide flows to the Gulf of Mexico, otherwise to the Labrador Sea or via the Great Lakes and St. Lawrence Seaway to the Gulf of St. Lawrence. Background From the divide's junction with the Continental Divide at Triple Divide Peak, just south of the U.S. border in northwestern Montana, it runs north to just across the border then east through southern Alberta and Saskatchewan where it turns southeasterly reentering the U.S. at the northwestern corner of North Dakota. It then continues to the extreme northeast corner of South Dakota before crossing the middle of Minnesota' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
