Mandan, Hidatsa, And Arikara Nation
The Mandan, Hidatsa, and Arikara Nation (MHA Nation), also known as the Three Affiliated Tribes (Mandan: ''Miiti Naamni''; Hidatsa: ''Awadi Aguraawi''; Arikara: ''ačitaanu' táWIt''), is a Native American Nation resulting from the alliance of the Mandan, Hidatsa, and Arikara peoples, whose native lands ranged across the Missouri River basin extending from present day North Dakota through western Montana and Wyoming. After the signing of the Fort Laramie Treaty (1851) and subsequent taking of land, the Nation's land base is currently approximately 1 million acres located Fort Berthold Reservation in northwestern North Dakota. The Tribe reported a total enrollment of 16,986 enrolled members of the Mandan, Hidatsa and Arikara Nation as of April 2022. Nearly 5,600 live on the Fort Berthold Indian Reservation; others live and work elsewhere.

Mandan Language
Mandan (Mandan: ''Nų́ų́ʔetaa íroo'') is an extinct Siouan language of North Dakota in the United States. Use and revitalization efforts By 2009, there was just one fluent speaker of Mandan, Dr. Edwin Benson (1931–2016). The language is being taught in local school programs to encourage the use of the language. Prior to Benson's death, Estonian linguist Indrek Park worked with him for more than two years to preserve the language as much as possible. The 2020 documentary ''To Save A Language'' portrays Park's efforts to revive the language. Mandan is taught at Fort Berthold Community College along with the Hidatsa and Arikara languages. Linguist Mauricio Mixco of the University of Utah has been involved in fieldwork with remaining speakers since 1993. As of 2007, extensive materials in the Mandan language at the college and at the North Dakota Heritage Center, in Bismarck, North Dakota, remained to be processed, according to linguists. The MHA Language Project has creat ...

Shoshone
The Shoshone or Shoshoni ( or ) are a Native American tribe with four large cultural/linguistic divisions: * Eastern Shoshone: Wyoming * Northern Shoshone: southern Idaho * Western Shoshone: Nevada, northern Utah * Goshute: western Utah, eastern Nevada They traditionally speak the Shoshoni language, part of the Numic languages branch of the large Uto-Aztecan language family. The Shoshone were sometimes called the Snake Indians by neighboring tribes and early American explorers. Their peoples have become members of federally recognized tribes throughout their traditional areas of settlement, often co-located with the Northern Paiute people of the Great Basin. Etymology The name "Shoshone" comes from ''Sosoni'', a Shoshone word for high-growing grasses. Some neighboring tribes call the Shoshone "Grass House People," based on their traditional homes made from ''sosoni''. Shoshones call themselves ''Newe'', meaning "People".Loether, Christopher"Shoshones."''Encyclopedia of the Gr ...

Great Plains
The Great Plains (french: Grandes Plaines), sometimes simply "the Plains", is a broad expanse of flatland in North America. It is located west of the Mississippi River and east of the Rocky Mountains, much of it covered in prairie, steppe, and grassland. It is the southern and main part of the Interior Plains, which also include the tallgrass prairie between the Great Lakes and Appalachian Plateau, and the Taiga Plains and Boreal Plains ecozones in Northern Canada. The term Western Plains is used to describe the ecoregion of the Great Plains, or alternatively the western portion of the Great Plains. The Great Plains lies across both Central United States and Western Canada, encompassing: * The entirety of the U.S. states of Kansas, Nebraska, North Dakota and South Dakota; * Parts of the U.S. states of Colorado, Iowa, Minnesota, Missouri, Montana, New Mexico, Oklahoma, Texas and Wyoming; * The southern portions of the Canadian provinces of Alberta, Saskatchewan and Manitoba. ...

Earth Lodge
An earth lodge is a semi-subterranean building covered partially or completely with earth, best known from the Native American cultures of the Great Plains and Eastern Woodlands. Most earth lodges are circular in construction with a dome-like roof, often with a central or slightly offset smoke hole at the apex of the dome. Earth lodges are well-known from the more-sedentary tribes of the Plains such as the Hidatsa, Mandan, and Arikara, but they have also been identified archaeologically among sites of the Mississippian culture in the eastern United States. Structure Construction materials and techniques Earth lodges were typically constructed using the wattle and daub technique, with a thick coating of earth. The dome-like shape of the earth lodge was achieved by the use of angled (or carefully bent) tree trunks, although hipped roofs were also sometimes used. During construction the workers would dig an area a few feet beneath the surface, allowing the entire building t ...

Flint
Flint, occasionally flintstone, is a sedimentary cryptocrystalline form of the mineral quartz, categorized as the variety of chert that occurs in chalk or marly limestone. Flint was widely used historically to make stone tools and start fires. It occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones.''The Flints from Portsdown Hill''
Inside the nodule, flint is usually dark grey, black, green, white or brown in colour, and often has a glassy or waxy appearance. A thin layer on the outside of the nodules is usually different in colour, typically white and rough in texture. The nodules can often be found along s and

Knife River
The Knife River is a tributary of the Missouri River, approximately 120 mi (193 km) long, in North Dakota in the United States. Knife is an English translation of the Native American name. It rises in west central North Dakota, in the Killdeer Mountains in Dunn County. It flows east, and is joined by Spring Creek near Beulah. It joins the Missouri north of Stanton, at the Knife River Indian Villages National Historic Site. Much of the terrain surrounding the river valley still remains in native grasslands, supporting many species of wildlife, including Whitetail Deer, Mule Deer, Coyote, Fox, Native Grouse, Pheasant, etc. Many of the small tributaries such as the Little Knife support local farms and ranches; some have been family owned for over 100 years. Some of the larger ranches include the Circle Five Ranch, Dressler Ranch, Perhus Bros. Ranch, and Greenshield Ranch. The river consistently floods after spring melting (frequently as high as 10,000 cfs) but is t ...

Maize
Maize ( ; ''Zea mays'' subsp. ''mays'', from es, maíz after tnq, mahiz), also known as corn (North American and Australian English), is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces pollen inflorescences (or "tassels") and separate ovuliferous inflorescences called ears that when fertilized yield kernels or seeds, which are fruits. The term ''maize'' is preferred in formal, scientific, and international usage as a common name because it refers specifically to this one grain, unlike ''corn'', which has a complex variety of meanings that vary by context and geographic region. Maize has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat or rice. In addition to being consumed directly by humans (often in the form of masa), maize is also used for corn ethanol, animal feed and other maize products, such as corn starch and ...

Shale Oil Extraction
Shale oil extraction is an industrial process for unconventional oil production. This process converts kerogen in oil shale into shale oil by pyrolysis, hydrogenation, or thermal dissolution. The resultant shale oil is used as fuel oil or upgraded to meet refinery feedstock specifications by adding hydrogen and removing sulfur and nitrogen impurities. Shale oil extraction is usually performed above ground (''ex situ'' processing) by mining the oil shale and then treating it in processing facilities. Other modern technologies perform the processing underground (on-site or ''in situ'' processing) by applying heat and extracting the oil via oil wells. The earliest description of the process dates to the 10th century. In 1684, Great Britain granted the first formal extraction process patent. Extraction industries and innovations became widespread during the 19th century. The industry shrank in the mid-20th century following the discovery of large reserves of conventional oil, ...
