Black Hills Meridian
The Black Hills meridian, longitude 104°03′ west from Greenwich, with the baseline in latitude 44° north, is the principal meridian that governs surveys in the state of South Dakota north and west of White River, and west of the Missouri River (between latitudes 45°55′20″ and 44°1′30″), the north and west boundaries of the Lower Brule Indian Reservation, and the west boundary of range 79 west, of the Fifth Principal Meridian system. It is named for the Black Hills of South Dakota and Wyoming.

Longitude
Longitude (, ) is a geographic coordinate that specifies the east– west position of a point on the surface of the Earth, or another celestial body. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda (λ). Meridians are semicircular lines running from pole to pole that connect points with the same longitude. The prime meridian defines 0° longitude; by convention the International Reference Meridian for the Earth passes near the Royal Observatory in Greenwich, England on the island of Great Britain. Positive longitudes are east of the prime meridian, and negative ones are west. Because of the Earth's rotation, there is a close connection between longitude and time measurement. Scientifically precise local time varies with longitude: a difference of 15° longitude corresponds to a one-hour difference in local time, due to the differing position in relation to the Sun. Comparing local time to an absolute measure of time a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prime Meridian (Greenwich)
The historic prime meridian or Greenwich meridian is a geographical reference line that passes through the Royal Observatory, Greenwich, in London, England. The modern IERS Reference Meridian widely used today is based on the Greenwich meridian, but differs slightly from it. This prime meridian (at the time, one of many) was first established by Sir George Airy in 1851, and by 1884, over two-thirds of all ships and tonnage used it as the reference meridian on their charts and maps. In October of that year, at the behest of US President Chester A. Arthur, 41 delegates from 25 nations met in Washington, D.C., United States, for the International Meridian Conference. This conference selected the meridian passing through Greenwich as the world standard prime meridian due to its popularity. However, France abstained from the vote, and French maps continued to use the Paris meridian for several decades. In the 18th century, London lexicographer Malachy Postlethwayt published ...

Latitude
In geography, latitude is a coordinate that specifies the north– south position of a point on the surface of the Earth or another celestial body. Latitude is given as an angle that ranges from –90° at the south pole to 90° at the north pole, with 0° at the Equator. Lines of constant latitude, or ''parallels'', run east–west as circles parallel to the equator. Latitude and ''longitude'' are used together as a coordinate pair to specify a location on the surface of the Earth. On its own, the term "latitude" normally refers to the ''geodetic latitude'' as defined below. Briefly, the geodetic latitude of a point is the angle formed between the vector perpendicular (or ''normal'') to the ellipsoidal surface from the point, and the plane of the equator. Background Two levels of abstraction are employed in the definitions of latitude and longitude. In the first step the physical surface is modeled by the geoid, a surface which approximates the mean sea level over the ocea ...

44th Parallel North
The 44th parallel north is a circle of latitude that is 44 degrees north of the Earth's equatorial plane. It crosses Europe, the Mediterranean Sea, Asia, the Pacific Ocean, North America, and the Atlantic Ocean. At this latitude the sun The Sun is the star at the center of the Solar System. It is a nearly perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions in its core. The Sun radiates this energy mainly as light, ultraviolet, and infrared radi ... is visible for 15 hours, 29 minutes during the summer solstice and 8 hours, 53 minutes during the winter solstice.

Principal Meridian
A principal meridian is a meridian used for survey control in a large region. Canada The Dominion Land Survey of Western Canada took its origin at the First (or Principal) Meridian, located at 97°27′28.41″ west of Greenwich, just west of Winnipeg, Manitoba. This line is exactly ten miles west of the Red River at the Canada–United States border. Six other meridians were designated at four-degree intervals westward, with the seventh located in British Columbia; the second and fourth meridians form the general eastern border and the western border of Saskatchewan. United States In the United States Public Land Survey System, a principal meridian is the principal north-south line used for survey control in a large region, and which divides townships between east and west. The meridian meets its corresponding baseline at the point of origin, or initial point, for the land survey. For example, the Mount Diablo Meridian, used for surveys in California and Nevada, runs north ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Dakota
South Dakota (; Sioux: , ) is a U.S. state in the North Central region of the United States. It is also part of the Great Plains. South Dakota is named after the Lakota and Dakota Sioux Native American tribes, who comprise a large portion of the population with nine reservations currently in the state and have historically dominated the territory. South Dakota is the seventeenth largest by area, but the 5th least populous, and the 5th least densely populated of the 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; President Benjamin Harrison shuffled the statehood papers before signing them so that no one could tell which became a state first. Pierre is the state capital, and Sioux Falls, with a population of about 192,200, is South Dakota's largest city. South Dakota is bordered by the states of North D ...

White River (Missouri River)
The White River is a Missouri River tributary that flows through the U.S. states of Nebraska and South Dakota. The name stems from the water's white-gray color, a function of eroded sand, clay, and volcanic ash carried by the river from its source near the Badlands. Draining a basin of about , about of which is in South Dakota, the stream flows through a region of sparsely populated hills, plateaus, and badlands. The White River rises in northwestern Nebraska, in the Pine Ridge escarpment north of Harrison, at an elevation of above sea level. It flows southeast then northeast past Fort Robinson and north of Crawford. It crosses into southwestern South Dakota and flows north across the Pine Ridge Indian Reservation, then northeast, receiving Wounded Knee Creek and flowing between units of Badlands National Park. It flows east-northeast and southeast at the northern edge of the reservation, forming the northern boundary of the reservation and the southern boundary of Buffalo Ga ...

Lower Brule Indian Reservation
The Lower Brulé Indian Reservation is an Indian reservation that belongs to the Lower Brulé Lakota Tribe. It is located on the west bank of the Missouri River in Lyman and Stanley counties in central South Dakota in the United States. It is adjacent to the Crow Creek Indian Reservation on the east bank of the river. The ''Kul Wicasa Oyate'' (''Khulwíčhaša Oyáte'', lower…men…nation), the Lower Brulé Sioux, are members of the Sicangu (Burnt Thigh), one of the bands of the Lakota Tribe. Tribal headquarters is in Lower Brule. History The Sioux consist of a group of self-governing tribes speaking one of three dialects of the Siouan language: Dakota, Nakota and Lakota. The Dakota or Santee, who identify as by the autonymns of Mdewakantonwan, Wahpetowan, Wahpekute, or Sisseton, range in territory from the Ohio River valley to South Dakota. The Dakota or Nakota, known as the Ihanktonwan/Yankton or Yanktonai/Ihanktonwanna, range from eastern Minnesota to the Missouri Rive ...

Black Hills
The Black Hills ( lkt, Ȟe Sápa; chy, Moʼȯhta-voʼhonáaeva; hid, awaxaawi shiibisha) is an isolated mountain range rising from the Great Plains of North America in western South Dakota and extending into Wyoming, United States. Black Elk Peak (formerly known as Harney Peak), which rises to , is the range's highest summit. The Black Hills encompass the Black Hills National Forest. The name of the hills in Lakota is ', meaning “the heart of everything that is." The Black Hills are considered a holy site. The hills are so called because of their dark appearance from a distance, as they are covered in evergreen trees. Native Americans have a long history in the Black Hills and consider it a sacred site. After conquering the Cheyenne in 1776, the Lakota took the territory of the Black Hills, which became central to their culture. In 1868, the U.S. government signed the Fort Laramie Treaty of 1868, establishing the Great Sioux Reservation west of the Missouri River, and ...

Wyoming
Wyoming () is a state in the Mountain West subregion of the Western United States. It is bordered by Montana to the north and northwest, South Dakota and Nebraska to the east, Idaho to the west, Utah to the southwest, and Colorado to the south. With a population of 576,851 in the 2020 United States census, Wyoming is the least populous state despite being the 10th largest by area, with the second-lowest population density after Alaska. The state capital and most populous city is Cheyenne, which had an estimated population of 63,957 in 2018. Wyoming's western half is covered mostly by the ranges and rangelands of the Rocky Mountains, while the eastern half of the state is high-elevation prairie called the High Plains. It is drier and windier than the rest of the country, being split between semi-arid and continental climates with greater temperature extremes. Almost half of the land in Wyoming is owned by the federal government, generally protected for public uses. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
