A city is a human settlement of a substantial size. The term "city" has different meanings around the world and in some places the settlement can be very small. Even where the term is limited to larger settlements, there is no universally agreed definition of the lower boundary for their size. In a narrower sense, a city can be defined as a permanent and densely populated place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing , transportation , sanitation , utilities , land use , production of goods , and communication . Their density facilitates interaction between people, government organizations , and businesses , sometimes benefiting different parties in the process, such as improving the efficiency of goods and service distribution.
135-518: El Reno is a city in and the county seat of Canadian County , Oklahoma , United States. As of the 2020 census , the city population was 16,989, marking a change of 1.55% from 16,729, recorded in the 2010 census . The city was begun shortly after the 1889 land rush and named for the nearby Fort Reno . It is located in Central Oklahoma , about 25 miles (40 km) west of downtown Oklahoma City. The land of Canadian County belonged to
270-471: A record-breaking multiple-vortex tornado . The tornado set a record with a width of 2.6 miles (4.2 km). Multiple storm chasers, including Mike Bettes and Dan Robinson, were injured, and Tim Samaras , Paul Samaras, and Carl Young of the TWISTEX team, alongside amateur Richard Henderson, were killed. An EF3 tornado struck southern parts of El Reno on May 25, 2019. Touching down at 10:32 pm,
405-445: A broad denuded area as a piedmont deposit by the rivers which issued from the mountains. Since then, it has been more or less dissected by the erosion of valleys. The central section of the plains thus presents a marked contrast to the northern section. While the northern section owes its smoothness to the removal of local gravels and sands from a formerly uneven surface by the action of degrading rivers and their inflowing tributaries,
540-602: A broad stretch of country underlain by nearly horizontal strata extending westward from the 97th meridian west to the base of the Rocky Mountains , a distance of 300 to 500 mi (480 to 800 km). It extends northward from the Mexican boundary far into Canada. Although the altitude of the plains increases gradually from 600 ft (180 m) or 1,200 ft (370 m) on the east to 4,000–5,000 ft (1,200–1,500 m) or 6,000 ft (1,800 m) near
675-577: A central area containing buildings with special economic, political, and religious significance. Archaeologists refer to this area by the Greek term temenos or if fortified as a citadel . These spaces historically reflect and amplify the city's centrality and importance to its wider sphere of influence . Today cities have a city center or downtown , sometimes coincident with a central business district . Cities typically have public spaces where anyone can go. These include privately owned spaces open to
810-665: A central authority. The term can also refer either to the physical streets and buildings of the city or to the collection of people who dwell there and can be used in a general sense to mean urban rather than rural territory . National censuses use a variety of definitions – invoking factors such as population , population density , number of dwellings , economic function, and infrastructure – to classify populations as urban. Typical working definitions for small-city populations start at around 100,000 people. Common population definitions for an urban area (city or town) range between 1,500 and 50,000 people, with most U.S. states using
945-461: A central point. This form could evolve from successive growth over a long time, with concentric traces of town walls and citadels marking older city boundaries. In more recent history, such forms were supplemented by ring roads moving traffic around the outskirts of a town. Dutch cities such as Amsterdam and Haarlem are structured as a central square surrounded by concentric canals marking every expansion. In cities such as Moscow , this pattern

Multiple movies have been filmed at least in part in El Reno, including: For many years the filmmaker George Kuchar would drive to El Reno to document the storm season, staying at the El Reno Motel. The result was his film Wild Night in El Reno. City Historically, city dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization , more than half of

The degree of urbanization is a modern metric to help define what comprises a city: "a population of at least 50,000 inhabitants in contiguous dense grid cells (>1,500 inhabitants per square kilometer)". This metric was "devised over years by the European Commission , OECD , World Bank and others, and endorsed in March [2021] by

The emergence of cities from proto-urban settlements , such as Çatalhöyük , is a non-linear development that demonstrates the varied experiences of early urbanization . The cities of Jericho , Aleppo , Byblos , Faiyum , Yerevan , Athens , Matera , Damascus , and Argos are among those laying claim to
1485-430: A distinctive elite social class, but it should indeed be considered a city based on a functional redefinition of urban development. In particular, Jenné-Jeno featured settlement mounds arranged according to a horizontal, rather than vertical, power hierarchy, and served as a center of specialized production and exhibited functional interdependence with the surrounding hinterland. More recently, scholars have concluded that

However, in Canada the eastern boundary of the plains is well defined by the presence of the Canadian Shield to the northeast. The plains (within the United States) may be described in northern, intermediate, central and southern sections, in relation to certain peculiar features. In Canada, no such division

By 1480, these cities, as far as still part of the empire, became part of the Imperial Estates governing the empire with the emperor through the Imperial Diet . By the 13th and 14th centuries, some cities become powerful states, taking surrounding areas under their control or establishing extensive maritime empires. In Italy, medieval communes developed into city-states including
2295-495: A rule cannot produce their own food and therefore must develop some relationship with a hinterland that sustains them. Only in special cases such as mining towns which play a vital role in long-distance trade, are cities disconnected from the countryside which feeds them. Thus, centrality within a productive region influences siting, as economic forces would, in theory, favor the creation of marketplaces in optimal mutually reachable locations.

A minority viewpoint considers that cities may have arisen without agriculture, due to alternative means of subsistence (fishing), to use as communal seasonal shelters, to their value as bases for defensive and offensive military organization, or to their inherent economic function. Cities played a crucial role in the establishment of political power over an area, and ancient leaders such as Alexander

9585-425: The Great Plains. The ornate box turtle ( Terrapene ornata ) and great plains skink ( Plestiodon obsoletus ) occur in southern areas. Although few salamanders are strongly associated with region, the western tiger salamander ( Ambystoma mavortium ) ranges through much of the Great Plains and the Rocky Mountains, as does the Rocky Mountain toad ( Anaxyrus w. woodhousi ). Other anurans related to region include
9720-503: The High Plains) is periodically subjected to extended periods of drought ; high winds in the region may then generate devastating dust storms . The eastern Great Plains near the eastern boundary falls in the humid subtropical climate zone in the southern areas, and the northern and central areas fall in the humid continental climate . Many thunderstorms occur in the plains in the spring through summer. The southeastern portion of
9855-741: The National Register of Historic Places, including the Carnegie Library , El Reno High School , and the Mennoville Mennonite Church . According to the United States Census Bureau , the city has a total area of 80.4 square miles (208 km), of which 80.0 square miles (207 km) are land and 0.4 square miles (1.0 km) (0.56%) is. water. El Reno is located at the interchange of I-40 and U.S. Route 81 . At one time, it sat on
9990-650: The Red, Brazos, and Colorado rivers of Texas and presents a ragged escarpment approximately 500 to 800 ft (150 to 240 m) high, overlooking the central denuded area of that state. There, between the Brazos and Colorado rivers, occurs a series of isolated outliers capped by limestone that underlies both the Llano Uplift on the west and the Grand Prairies escarpment on the east. The southern and narrow part of
10125-423: The age of 18 living with them, 50.0% were married couples living together, 12.7% had a female householder with no husband present, and 32.9% were not families. About 28.5% of all households were made up of individuals, and 12.7% had someone living alone who was 65 years of age or older. The average household size was 2.50 and the average family size was 3.08. In the city, the population was distributed as 24.2% under
10260-443: The age of 18, 10.5% from 18 to 24, 30.8% from 25 to 44, 21.1% from 45 to 64, and 13.4% who were 65 years of age or older. The median age was 35 years. For every 100 females, there were 114.7 males. For every 100 females age 18 and over, there were 119.5 males. The median income for a household in the city was $ 31,200, and for a family was $ 39,106. Males had a median income of $ 29,521 versus $ 20,107 for females. The per capita income for
10395-536: The ancient capital of Ghana, and Maranda , a center located on a trade route between Egypt and Gao. The dissolution of the Roman Empire in the West was connected with profound changes in urban fabric of western Europe. In places where Roman administration quickly weakened urbanism went through a profound crisis, even if it continued to remain an important symbolic factor. In regions like Italy or Spain cities diminished in size but nevertheless continued to play
10530-716: The area of the ancient Great Plains for thousands to millions of years. The vast majority of these animals became extinct in North America at the end of the Pleistocene (around 13,000 years ago). A number of significant fossil sites are located in the Great Plains including Agate Fossil Beds National Monument ( Nebraska ), Ashfall Fossil Beds ( Nebraska ), Clayton Lake State Park ( New Mexico ), Dinosaur Valley State Park ( Texas ), Hudson-Meng Bison Kill (Nebraska), Makoshika State Park (Montana), and The Mammoth Site ( South Dakota ). Public and protected lands in
10665-464: The athletic, artistic, spiritual, and political life of the polis. Rome was the first city that surpassed one million inhabitants. Under the authority of its empire , Rome transformed and founded many cities ( Colonia ), and with them brought its principles of urban architecture, design, and society. In the ancient Americas , early urban traditions developed in the Andes and Mesoamerica . In
10800-407: The benefit of mitigating the urban heat island effect, especially in cities that are in warmer climates. These spaces prevent carbon imbalances, extreme habitat losses, electricity and water consumption, and human health risks. The urban structure generally follows one or more basic patterns: geomorphic, radial, concentric, rectilinear, and curvilinear. The physical environment generally constrains
10935-601: The boundary between Oklahoma Territory and Indian Territory , and sits approximately 20 miles (32 km) west of the old Chisholm Trail . Jesse Chisholm is buried nearby. El Reno has endured numerous weather-related incidents. On May 24, 2011 , the violent and long-tracking 2011 El Reno–Piedmont tornado , an EF5 tornado, struck parts of northwestern El Reno. The tornado killed a total of 9 people, injured 181 others, and had winds measured at up to 295 mph by mobile doppler radar near Interstate 40 . Two years later, on May 31, 2013, rural areas near El Reno were hit by
11070-437: The celebration of art, music, culture, food and community. Visitors can observe the cooking of the world's largest fried onion hamburger , weighing over 850 lb (390 kg). The giant burger contains meat, fried onions, sliced pickles, and mustard - all held between two giant buns. Festival goers can get a piece of the monstrosity. Volunteers divide the giant burger into individual-sized portions, and other volunteers deliver
11205-471: The central section, it is for the most part a dissected fluviatile plain. However, the lower lands which surround it on all sides place it in such strong relief that it stands up as a table-land, known from the time of Mexican occupation as the Llano Estacado . It measures roughly 150 mi (240 km) east-west and 400 mi (640 km) north-south. It is of very irregular outline, narrowing to
11340-494: The city was $ 15,570. About 11.4% of families and 16.3% of the population were below the poverty line , including 19.6% of those under age 18 and 10.4% of those age 65 or over. The City of El Reno operates under a council-manager government system. City employees include the city manager , finance director, police chief, fire chief, city clerk, public works director, code enforcement director, community services director, and city librarian. The Federal Bureau of Prisons operates
11475-447: The city. The population density was 202.7 inhabitants per square mile (78.3/km). The 6,484 housing units averaged 81.1 units per square mile (31.3 units/km). The racial makeup of the city was 71.8% White, 11.1% Native American, 7.2% African American, 0.5% Asian, 4.7% from other races, and 4.7% from two or more races. Hispanics or Latinos of any race were 12.9% of the population. Of the 5,727 households, which 31.7% had children under
11610-514: The community township or Village of (El) Reno. The Village of El Reno originated shortly after the 1889 land run, with the post office coming into being in June of that year. Although "el reno" means "the reindeer " in Spanish , the town was actually named, in part, after nearby Fort Reno. Reindeer are not native to Oklahoma. The town's name was taken from the nearby military post of Fort Reno, with
11745-542: The early Old World cities, Mohenjo-daro of the Indus Valley civilization in present-day Pakistan , existing from about 2600 BC, was one of the largest, with a population of 50,000 or more and a sophisticated sanitation system . China's planned cities were constructed according to sacred principles to act as celestial microcosms . The Ancient Egyptian cities known physically by archaeologists are not extensive. They include (known by their Arab names) El Lahun ,
11880-484: The emergence of an Atlantic trade. However, most towns remained small. During the Spanish colonization of the Americas, the old Roman city concept was extensively used. Cities were founded in the middle of the newly conquered territories and were bound to several laws regarding administration, finances, and urbanism. The growth of the modern industry from the late 18th century onward led to massive urbanization and
12015-531: The encroachment of European settlers as well as economic incentives such as the fur trade, alongside the arrival of the horse and firearms from Europe pushed multiple tribes onto the Great Plains. Among those to have lived on the Great Plains were the Blackfoot , Crow , Sioux , Cheyenne , Arapaho , Comanche , and others. Eastern portions of the Great Plains were inhabited by tribes who lived at Etzanoa and in semi-permanent villages of earth lodges, such as
12150-812: The first millennium AD, the Khmer capital of Angkor in Cambodia grew into the most extensive preindustrial settlement in the world by area, covering over 1,000 km and possibly supporting up to one million people. West Africa already had cities before the Common Era , but the consolidation of Trans-Saharan trade in the Middle Ages multiplied the number of cities in the region, as well as making some of them very populous, notably Gao (72,000 inhabitants in 800 AD), Oyo-Ile (50,000 inhabitants in 1400 AD, and may have reached up to 140,000 inhabitants in
12285-440: The form in which a city is built. If located on a mountainside, urban structures may rely on terraces and winding roads. It may be adapted to its means of subsistence (e.g. agriculture or fishing). And it may be set up for optimal defense given the surrounding landscape. Beyond these "geomorphic" features, cities can develop internal patterns, due to natural growth or to city planning . In a radial structure, main roads converge on
12420-574: The free portions to anyone in the crowd wanting a piece. The fried onion burger dates to the Great Depression , when households added onions to ground hamburger mix to stretch out the meat supply. In 2001, El Reno was the first city in Oklahoma to re-establish streetcar service in the downtown area: the Heritage Express Trolley . Such service had not been available since 1947, and it was the only operating trolley line in
12555-433: The general level by 500 ft (150 m) or more and manifestly demonstrating the widespread erosion of the surrounding plains. All these reliefs are more plentiful towards the mountains in central Montana. The peneplain is no longer in the cycle of erosion that witnessed its production. It appears to have suffered a regional uplift or increase in elevation, for the upper Missouri River and its branches no longer flow on
12690-517: The geographical agencies of the Mexican, American, and Canadian governments, uses the "Great Plains" as an ecoregion synonymous with predominant prairies and grasslands rather than as physiographic region defined by topography. The Great Plains ecoregion includes five sub-regions: Temperate Prairies, West-Central Semi-Arid Prairies, South-Central Semi-Arid Prairies, Texas Louisiana Coastal Plains, and Tamaulipas-Texas Semi-Arid Plain, which overlap or expand upon other Great Plains designations. The region
12825-760: The great plains like the Rocky Mountain Locust (Melanoplus spretus). During the Cretaceous Period (145–66 million years ago), the Great Plains were covered by a shallow inland sea called the Western Interior Seaway . However, during the Late Cretaceous to the Paleocene (65–55 million years ago), the seaway had begun to recede, leaving behind thick marine deposits and a relatively flat terrain which
12960-493: The historic Cheyenne and Arapaho tribes at the time of European encounter. In 1874, the United States established a fort to supervise the area and General Philip Sheridan took command. He named it Fort Reno in honor of his friend, Gen. Jesse L. Reno , who was killed in the American Civil War . After the 1889 landrun, there were three entities the local postmaster had to keep separate - Fort Reno, Reno City, and
13095-466: The homestead of John Foreman. In 1890, Foreman's 120 acres along with 80 acres of Thomas Jensen's, were incorporated into the Village of El Reno. After the railroad company announced their rail lines were going to run on the south side of the Canadian river, Reno City relocated to the township of El Reno. The original Reno City site north of the river was abandoned. What remained and continues to this day
13230-800: The international community has prioritized investment in sustainable cities through Sustainable Development Goal 11 . Due to the efficiency of transportation and the smaller land consumption , dense cities hold the potential to have a smaller ecological footprint per inhabitant than more sparsely populated areas. Therefore, compact cities are often referred to as a crucial element in fighting climate change. However, this concentration can also have some significant negative consequences, such as forming urban heat islands , concentrating pollution , and stressing water supplies and other resources. A city can be distinguished from other human settlements by its relatively great size, but also by its functions and its special symbolic status , which may be conferred by
13365-472: The land surface of the Earth. Town siting has varied through history according to natural, technological, economic, and military contexts. Access to water has long been a major factor in city placement and growth, and despite exceptions enabled by the advent of rail transport in the nineteenth century, through the present most of the world's urban population lives near the coast or on a river. Urban areas as
13500-501: The largest group. They rise like a large island from the sea, occupying an oval area of about 100 mi (160 km) north-south by 50 mi (80 km) east-west. At Black Elk Peak , they reach an altitude of 7,216 ft (2,199 m) and have an effective relief over the plains of 2,000 or 3,000 ft (610 or 910 m) This mountain mass is of flat-arched, dome-like structure, now well dissected by radiating consequent streams. The weaker uppermost strata have been eroded down to
13635-468: The least protected biomes. Humans have converted much of the prairies for agricultural purposes or to create pastures. Several of the protected lands in the region are centered around aberrant and uncharacteristic features of the region, such as mountains, outcrops, and canyons (e.g. Devil's Tower National Monument , Wind Cave National Park , Scotts Bluff National Monument ), and as splendid and worthy as they are, they are not primarily focused on conserving
13770-426: The level of the plains where their upturned edges are evenly truncated. The next following harder strata have been sufficiently eroded to disclose the core of underlying igneous and metamorphic crystalline rocks in about half of the domed area. In the intermediate section of the plains, between latitudes 44° and 42° , including southern South Dakota and northern Nebraska , the erosion of certain large districts
13905-484: The line that divides the Great Plains into an area that receives 20 in (510 mm) or more of rainfall per year and an area that receives less than 20 in (510 mm). In this context, the High Plains, as well as Southern Alberta , south-western Saskatchewan and Eastern Montana are mainly semi arid steppe land and are generally characterised by rangeland or marginal farmland . The region (especially
14040-475: The longest continual inhabitation . Cities, characterized by population density , symbolic function, and urban planning , have existed for thousands of years. In the conventional view, civilization and the city were both followed by the development of agriculture , which enabled the production of surplus food and thus a social division of labor (with concomitant social stratification ) and trade . Early cities often featured granaries , sometimes within
14175-760: The more common "prairie". The Great Plains are the westernmost portion of the vast North American Interior Plains , which extend east to the Appalachian Plateau . The United States Geological Survey divides the Great Plains in the United States into ten physiographic subdivisions: Further to this can be added Canadian physiographic sub-regions such as the Alberta Plain, Cypress Hills , Manitoba Escarpment (eastward), Manitoba Plain, Missouri Coteau (shared), Rocky Mountain Foothills (eastward), and Saskatchewan Plain. The Great Plains consist of
14310-442: The mountains, the local relief is generally small. The semi-arid climate excludes tree growth and opens far-reaching views. The plains are by no means a simple unit. They are of diverse structure and of various stages of erosional development. They are occasionally interrupted by buttes and escarpments . They are frequently broken by valleys. Yet on the whole, a broadly extended surface of moderate relief so often prevails that
14445-497: The multi-millions, have proliferated into the dozens, arising especially in Asia, Africa, and Latin America. Economic globalization fuels the growth of these cities, as new torrents of foreign capital arrange for rapid industrialization, as well as the relocation of major businesses from Europe and North America, attracting immigrants from near and far. A deep gulf divides the rich and poor in these cities, which usually contain
14580-436: The name, Great Plains, for the region as a whole is well-deserved. The western boundary of the plains is usually well-defined by the abrupt ascent of the mountains. The eastern boundary of the plains (in the United States) is more climatic than topographic . The line of 20 in (510 mm) of annual rainfall trends a little east of northward near the 97th meridian. If a boundary must be drawn where nature presents only
14715-612: The patty meant that owner Ross Davis could use less meat in his five-cent burgers. On June 15, 2015, Sid's Diner was featured on the Food Network series Top 5 Restaurants , with their fried-onion burger being highlighted. Sid's Diner has also been featured on the Travel Channel series Man v. Food . Since 1988 El Reno holds an annual Fried Onion Burger Day Festival in downtown the first Saturday in May. This event encourages
14850-434: The plains and prairies. United States: Canada: the Great Plains biome is found to be at the brink of collapse due to woody plant encroachment , with 62% of Northern American grassland lost to date. The first Peoples ( Paleo-Indians ) arrived on the Great Plains thousands of years ago. The introduction of corn around 800 CE allowed the development of the mound-building Mississippian culture along rivers that crossed
14985-500: The public as well as forms of public land such as public domain and the commons . Western philosophy since the time of the Greek agora has considered physical public space as the substrate of the symbolic public sphere . Public art adorns (or disfigures) public spaces. Parks and other natural sites within cities provide residents with relief from the hardness and regularity of typical built environments . Urban green spaces are another component of public space that provides
15120-489: The railroad honors El Reno as a "Train Town USA," one of 131 communities out of 7,300 communities it serves, because of the town's unique, long-standing relationship with the line. Public school districts with parts of El Reno include: El Reno Public Schools , Banner Public School , Darlington Public School , Maple Public School , and Riverside Public School . The El Reno Tribune publishes Wednesday and Sunday and has
15255-647: The region. Other species migrate from the south in the spring and spend their breeding season on the plains, including the white-faced ibis ( Plegadis chihi ), mountain plover ( Charadrius montanus ), marbled godwit ( Limosa fedoa ), Sprague's pipit ( Anthus spragueii ), Cassin's sparrow ( Peucaea cassinii ), Baird's sparrow ( Centronyx bairdii ), lark bunting ( Calamospiza melanocorys ), chestnut-collared longspur ( Calcarius ornatus ), thick-billed longspur or McCown's longspur ( Rhynchophanes mccownii ), and dickcissel ( Spiza americana ). The prairie rattlesnake ( Crotalus viridis ) ranges throughout much of
15390-810: The rise of new great cities, first in Europe and then in other regions, as new opportunities brought huge numbers of migrants from rural communities into urban areas. England led the way as London became the capital of a world empire and cities across the country grew in locations strategic for manufacturing . In the United States from 1860 to 1910, the introduction of railroads reduced transportation costs, and large manufacturing centers began to emerge, fueling migration from rural to city areas. Some industrialized cities were confronted with health challenges associated with overcrowding , occupational hazards of industry, contaminated water and air, poor sanitation , and communicable diseases such as typhoid and cholera . Factories and slums emerged as regular features of
15525-474: The river from a better graded preglacial valley by the Pleistocene ice sheet . Here, the ice sheet overspread the plains from the moderately elevated Canadian highlands far on the north-east, instead of from the much higher mountains nearby on the west. The present altitude of the plains near the mountain base is 4,000 ft (1,200 m). The northern plains are interrupted by several small mountain areas. The Black Hills, chiefly in western South Dakota, are
15660-698: The same location as Tenochtitlan ; while ancient continuously inhabited Pueblos are near modern urban areas in New Mexico , such as Acoma Pueblo near the Albuquerque metropolitan area and Taos Pueblo near Taos ; while others like Lima are located nearby ancient Peruvian sites such as Pachacamac . From 1600 BC, Dhar Tichitt , in the south of present-day Mauritania , presented characteristics suggestive of an incipient form of urbanism. The second place to show urban characteristics in West Africa
15795-565: The seaway had once occupied. During the Cenozoic era , specifically about 25 million years ago during the Miocene and Pliocene epochs, the continental climate became favorable to the evolution of grasslands. Existing forest biomes declined and grasslands became much more widespread. The grasslands provided a new niche for mammals, including many ungulates and glires , that switched from browsing diets to grazing diets. Traditionally,
15930-405: The south. Its altitude is 5,500 ft (1,700 m) at the highest western point, nearest the mountains whence its gravels were supplied. From there, it slopes southeastward at a decreasing rate, first about 12 ft (3.7 m), then about 7 ft/mi (1.3 m/km), to its eastern and southern borders, where it is 2,000 ft (610 m) in altitude. Like the High Plains farther north, it
16065-459: The southern section owes its smoothness to the deposition of imported gravels and sands upon a previously uneven surface by the action of aggrading rivers and their outgoing distributaries. The two sections are also alike in that residual eminences still here and there surmount the peneplain of the northern section, while the fluviatile plain of the central section completely buried the pre-existent relief. An exception to this statement must be made for
16200-416: The southwest, close to the mountains in southern Colorado, where some lava-capped mesas ( Mesa de Maya , Raton Mesa ) stand several thousand feet above the general plain level, and thus testify to the widespread erosion of this region before it was aggraded. The southern section of the Great Plains, between latitudes 35.5° and 25.5°, lies in western Texas , eastern New Mexico , and western Oklahoma . Like
16335-588: The spread of grasslands and the development of grazers have been strongly linked. However, an examination of mammalian teeth suggests that it is the open, gritty habitat and not the grass itself which is linked to diet changes in mammals, giving rise to the " grit, not grass " hypothesis. Paleontological finds in the area have yielded bones of mammoths , saber-toothed cats and other ancient animals, as well as dozens of other megafauna (large animals over 100 lb [45 kg]) – such as giant sloths , horses , mastodons , and American lion – that dominated
16470-638: The state that year. Another line has since been started in Oklahoma City . The Heritage Express was installed with aid of a federal transportation grant and as part of a complex project also to improve the downtown's streets and drainage system. The former train depot and some other buildings were acquired by the Canadian County Historical Society for adaptive use as part of a museum complex. The 1954 film noir Human Desire includes locomotive and yard scenes filmed in
16605-657: The subdued forms of the Wichita Mountains in Oklahoma , the westernmost member of the Ouachita system. The term "Western Plains" is used to describe the ecoregion of the Great Plains, or alternatively the western portion of the Great Plains. In general, the Great Plains have a wide range of weather, with very cold and harsh winters and very hot and humid summers. Wind speeds are often very high, especially in winter. The 100th meridian roughly corresponds with
16740-464: The surface of the plain, but in well graded, maturely opened valleys, several hundred feet below the general level. A significant exception to the rule of mature valleys occurs, however, in the case of the Missouri, the largest river, which is broken by several falls on hard sandstones about 50 mi (80 km) east of the mountains. This peculiar feature is explained as the result of displacement of
16875-590: The table-land, called the Edwards Plateau , is more dissected than the rest, and falls off to the south in a frayed-out fault scarp. This scarp overlooks the coastal plain of the Rio Grande embayment . The central denuded area, east of the Llano, resembles the east-central section of the plains in exposing older rocks. Between these two similar areas, in the space limited by the Canadian and Red Rivers, rise
17010-489: The term and has challenged geographers seeking to classify territories according to an urban-rural binary. Metropolitan areas include suburbs and exurbs organized around the needs of commuters , and sometimes edge cities characterized by a degree of economic and political independence. (In the US these are grouped into metropolitan statistical areas for purposes of demography and marketing .) Some cities are now part of
17145-404: The tornado damaged a service station before moving east-northeastward and crossing Interstate 40. It damaged billboards before striking a motel and a mobile home park at U.S. Highway 81, both of which suffered significant damage. One part of the motel had most of its second-floor walls destroyed, and several mobile homes were destroyed, killing two people and injuring many others. East of Highway 81,
17280-516: The tornado damaged an automobile service building and a house on Route 66. The tornado caused tree damage before dissipating on Alfadale Road north of Route 66. The tornado had a maximum estimated width of 75 yards (69 m) and injured 19 people. El Reno is part of the Oklahoma City Metropolitan Statistical Area . As of the census of 2010, 16,749 people, 5,727 households, and 3,842 families resided in
17415-412: The turn of the first millennium BC , encompassed numerous cities extending from Tyre , Cydon , and Byblos to Carthage and Cádiz . In the following centuries, independent city-states of Greece , especially Athens , developed the polis , an association of male landowning citizens who collectively constituted the city. The agora , meaning "gathering place" or "assembly", was the center of
17550-446: The urban landscape. In the second half of the 20th century, deindustrialization (or " economic restructuring ") in the West led to poverty , homelessness , and urban decay in formerly prosperous cities. America's "Steel Belt" became a " Rust Belt " and cities such as Detroit , Michigan, and Gary, Indiana began to shrink , contrary to the global trend of massive urban expansion. Such cities have shifted with varying success into
17685-535: The volume of sewage begins to exceed manageable levels. The local government of cities takes different forms including prominently the municipality (especially in England , in the United States , India , and other British colonies ; legally, the municipal corporation ; municipio in Spain and Portugal , and, along with municipalidad , in most former parts of the Spanish and Portuguese empires) and
17820-523: The world's population lived in cities. The cultural appeal of cities also plays a role in attracting residents. Urbanization rapidly spread across Europe and the Americas and since the 1950s has taken hold in Asia and Africa as well. The Population Division of the United Nations Department of Economic and Social Affairs reported in 2014 that for the first time, more than half of the world population lives in cities. Latin America
17955-543: Was Dia , in present-day Mali , from 800 BC. Both Dhar Tichitt and Dia were founded by the same people: the Soninke , who would later also found the Ghana Empire . Another ancient site, Jenné-Jeno , in what is today Mali , has been dated to the third century BCE. According to Roderick and Susan McIntosh, Jenné-Jeno did not fit into traditional Western conceptions of urbanity as it lacked monumental architecture and
18090-577: Was not generally used before the early 20th century. Nevin Fenneman's 1916 study Physiographic Subdivision of the United States brought the term Great Plains into more widespread usage. Before that the region was almost invariably called the High Plains, in contrast to the lower Prairie Plains of the Midwestern states . Today the term " High Plains " is used for a subregion of the Great Plains. The term still remains little-used in Canada compared to
18225-543: Was the site of a prisoner of war camp for Germans and Italians. The POW cemetery has been preserved and has stones bearing the names of German and Italian prisoners who died there. Following World War II, the US Army determined it did not need the fort. In 1948 the fort was transferred to the U.S. Department of Agriculture , for use as a research laboratory . The laboratory studies environmentally sustainable forage and livestock production, contributing to preservation of
