Drift Prairie
The Drift Prairie is a geographic region of North Dakota and South Dakota. In North Dakota, the Drift Prairie is the transition zone between two zones. The gently rolling hills and shallow lakes were formed by glacial action, while the Badlands to the west are characterized by the lack of this action, and the Red River Valley to the east was a lake bed. This distinction causes the area considered as Drift Prairie to overlap somewhat with the Missouri Plateau, another of North Dakota's distinct geographic regions, but the Drift Prairie also includes the Souris River basin. Prairie grasses and wheat grow there making it a perfect place for ranchers. The prairie is filled with drift. Drift is soil consisting of clay, sand, and gravel. In South Dakota, most of the eastern state is covered by the Drift Prairie. The Missouri River cuts through the center of the state. To the east of the river are low hills and lakes formed by glaciers referred to as the Drift Prairie. The area is bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Dakota
North Dakota () is a U.S. state in the Upper Midwest, named after the indigenous Dakota Sioux. North Dakota is bordered by the Canadian provinces of Saskatchewan and Manitoba to the north and by the U.S. states of Minnesota to the east, South Dakota to the south, and Montana to the west. It is believed to host the geographic center of North America, Rugby, and is home to the tallest man-made structure in the Western Hemisphere, the KVLY-TV mast. North Dakota is the 19th largest state, but with a population of less than 780,000 as of 2020, it is the 4th least populous and 4th most sparsely populated. The capital is Bismarck while the largest city is Fargo, which accounts for nearly a fifth of the state's population; both cities are among the fastest-growing in the U.S., although half of all residents live in rural areas. The state is part of the Great Plains region, with broad prairies, steppe, temperate savanna, badlands, and farmland being defining characteris ...

South Dakota
South Dakota (; Sioux language, Sioux: , ) is a U.S. state in the West North Central states, North Central region of the United States. It is also part of the Great Plains. South Dakota is named after the Lakota people, Lakota and Dakota people, Dakota Sioux Native Americans in the United States, Native American tribes, who comprise a large portion of the population with nine Indian reservation, reservations currently in the state and have historically dominated the territory. South Dakota is the List of U.S. states and territories by area, seventeenth largest by area, but the List of U.S. states and territories by population, 5th least populous, and the List of U.S. states and territories by population density, 5th least densely populated of the List of U.S. states, 50 United States. As the southern part of the former Dakota Territory, South Dakota became a state on November 2, 1889, simultaneously with North Dakota. They are the 39th and 40th states admitted to the union; Pr ...

Glaciation
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. The Holocene is the current interglacial. A time with no glaciers on Earth is considered a greenhouse climate state. Quaternary Period Within the Quaternary, which started about 2.6 million years before present, there have been a number of glacials and interglacials. At least eight glacial cycles have occurred in the last 740,000 years alone. Penultimate Glacial Period The Penultimate Glacial Period (PGP) is the glacial period that occurred before the Last Glacial Period. It began about 194,000 years ago and ended 135,000 years ago, with the beginning of the Eemian interglacial. Last Glacial Period The last glacial period was the most recent glacial peri ...

Badlands
Badlands are a type of dry terrain where softer sedimentary rocks and clay-rich soils have been extensively eroded."Badlands" in '' Chambers's Encyclopædia''. London: George Newnes, 1961, Vol. 2, p. 47. They are characterized by steep slopes, minimal vegetation, lack of a substantial regolith, and high drainage density.A.J. Parsons and A.D. Abrahams, Editors (2009) ''Geomorphology of Desert Environments'' (2nd ed.) Springer Science & Business Media Ravines, gullies, buttes, hoodoos and other such geologic forms are common in badlands. Badlands are found on every continent except Antarctica, being most common where there are unconsolidated sediments. They are often difficult to navigate by foot, and are unsuitable for agriculture. Most are a result of natural processes, but destruction of vegetation by overgrazing or pollution can produce anthropogenic badlands. Badlands topography Badlands are characterized by a distinctive badlands topography. This is terrain i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red River Valley
The Red River Valley is a region in central North America that is drained by the Red River of the North; it is part of both Canada and the United States. Forming the border between Minnesota and North Dakota when these territories were admitted as states in the United States, this fertile valley has been important to the economies of these states and to Manitoba, Canada. The population centers of Moorhead, Minnesota, Fargo and Grand Forks, North Dakota, and Winnipeg, Manitoba developed in the valley as settlement by ethnic Europeans increased in the late nineteenth century. Completion of major railroads, availability of cheap lands, and forceful removal of Indigenous people as well as a subsequent refusal to recognize Indigenous land claims attracted many new settlers. Some developed large-scale agricultural operations known as bonanza farms, which concentrated on wheat commodity crops. Paleogeographic Lake Agassiz laid down the Red River Valley Silts. The valley was long an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Missouri Plateau
The Missouri Coteau, or Missouri Plateau, (french: Coteau du Missouri) is a large plateau that stretches along the eastern side of the valley of the Missouri River in central North Dakota and north-central South Dakota in the United States. In the Canadian provinces of Saskatchewan and Alberta this physiographic region is classified as the Uplands Missouri Coteau, which is a part of the Great Plains Province or Alberta Plateau Region, which extends across the southwest corner of the province of Saskatchewan as well as the southeast corner of the province of Alberta. Historically, in Canada the area was known as the Palliser's Triangle and regarded as an extension of the Great American Desert and unsuitable for agriculture and thus designated by Canadian geographer and explorer John Palliser. The terrain of the Missouri Coteau features low hummocky, undulating, rolling hills, potholes, and grasslands. Apart from being a geographical area, the Missouri Coteau also has a cultural co ...

Souris River
The Souris River (; french: rivière Souris) or Mouse River (as it is alternatively known in the U.S., a calque of its French name) is a river in central North America. It is about in length and drains about . It rises in the Yellow Grass Marshes north of Weyburn, Saskatchewan. It wanders south through North Dakota beyond Minot to its most southern point at the city of Velva, and then back north into Manitoba. The river passes through the communities of Melita, Hartney, Souris and Wawanesa and on to its confluence with the Assiniboine River near Treesbank, about southeast of Brandon. The main tributaries which flow into the Souris in Manitoba are the Antler River, the Gainsborough, and Plum Creeks. At the end of the last ice age over 10,000 years ago the rapid draining of former Glacial Lake Regina eroded a large channel that is now occupied by the much smaller contemporary Souris River. Also, much of the drainage basin is fertile silt and clay deposited by another ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Minnesot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geography Of North Dakota
The Geography of North Dakota consists of three major geographic regions: in the east is the Red River Valley, west of this, the Missouri Plateau. The southwestern part of North Dakota is covered by the Great Plains, accentuated by the Badlands. There is also much in the way of geology and hydrology. North Dakota is about 340 miles (545 km) east to west and 211 miles (340 km) north to south, with a total area of 70,704 square miles (183,123 km²), making it the 19th largest of the 50 U.S. states. About 2.4% of North Dakota's area is covered by water. Geographic divisions The Red River Valley The Red River Valley takes up the eastern portion of the state, with the Red River of the North forming the border with Minnesota. The Valley is the remnant lake bed of the ancient Lake Agassiz. It is very flat, and is quite fertile. This area of North Dakota is mostly farm country, with wheat, sugarbeets, and maize as staple crops, and along with other crops and livestock ...

Geography Of South Dakota
South Dakota is a state located in the north-central United States. It is usually considered to be in the Midwestern region of the country. The state can generally be divided into three geographic regions: eastern South Dakota, western South Dakota, and the Black Hills. Eastern South Dakota is lower in elevation and higher in precipitation than the western part of the state, and the Black Hills are a low, isolated mountain group in the southwestern corner of the state. Smaller sub-regions in the state include the Coteau des Prairies, Missouri Coteau, James River Valley, the Dissected Till Plains. Geologic formations in South Dakota range in age from two billion-year-old Precambrian granite in the Black Hills to glacial till deposited over the last few million years. South Dakota is the 17th-largest state in the country. South Dakota has a humid continental climate in the east and in the Black Hills, and a semi-arid climate in the west outside of the Black Hills, featuring four ...
