72-505: The Schoolhouse Blizzard , also known as the Schoolchildren's Blizzard , School Children's Blizzard , or Children's Blizzard , hit the U.S. Great Plains on January 12, 1888. With an estimated 235 deaths , it is the world's 10th deadliest winter storm on record. The blizzard came unexpectedly on a relatively warm day, and many people were caught unaware, including children in one-room schoolhouses . The weather prediction for

144-445: 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,

216-602: 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

288-772: A few horses were found by the Spanish among the Indians living at the mouth of the Colorado River of Texas and the Caddo of eastern Texas had a sizeable number. Great Blizzard of 1888 The weather was unseasonably mild just before the blizzard, with heavy rains that turned to snow as temperatures dropped rapidly. On March 12, New York City dropped from 33 °F (1 °C) to 8 °F (−13 °C), and rain changed to snow at 1am. The storm began in earnest shortly after midnight on March 12 and continued unabated for

360-492: A full day and a half. In a 2007 article, the National Weather Service estimated that this nor'easter dumped as much as 50 inches (130 cm) of snow in parts of Connecticut and Massachusetts, while parts of New Jersey and New York had up to 40 inches (100 cm). Most of northern Vermont received from 20 inches (51 cm) to 30 inches (76 cm). Drifts averaged 30–40 feet (9.1–12.2 m), over

432-603: A gradual transition, this rainfall line may be taken to divide the drier plains from the moister prairies. 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

504-524: A spread of over 780 miles (1,255 km). The blizzard was precipitated by the collision of an immense Arctic cold front with warm moisture-laden air from the Gulf of Mexico . Within a few hours, the advancing cold front caused a temperature drop from a few degrees above freezing to −20 °F (−29 °C) [−40 °F (−40 °C) in some places]. This wave of cold was accompanied by high winds and heavy snow . The fast-moving storm first struck Montana in

576-521: A strengthening surface low dropped south-southeastward out of the Alberta District in Canada's North-West Territories into central Montana Territory and then into northeastern Colorado by the morning of January 12. The temperatures in advance of the low increased some 20 to 40 °F (11–22 °C) in the central plains (for example, Omaha, Nebraska , recorded a temperature of −6 °F (−21 °C) at 7 a.m. on January 11, while

648-594: A west-northwest direction in what is now Oklahoma and Texas which is now known as the De Soto Trail. The Spanish thought that the Great Plains were the location of the mythological Quivira and Cíbola , a place said to be rich in gold. People in the southwest began to acquire horses in the 16th century by trading or stealing them from Spanish colonists in New Mexico. As horse culture moved northward,

720-404: Is about 500 mi (800 km) east to west and 2,000 mi (3,200 km) north to south. Much of the region was home to American bison herds until they were hunted to near extinction during the mid/late-19th century. It has an area of approximately 500,000 sq mi (1,300,000 km ). Current thinking regarding the geographic boundaries of the Great Plains is shown by this map at

792-526: Is extraordinarily smooth. It is very dry, except for occasional shallow and temporary water sheets after rains. Llano is separated from the plains on the north by the mature consequent valley of the Canadian River , and from the mountains on the west by the broad and probably mature valley of the Pecos River . On the east, it is strongly undercut by the retrogressive erosion of the headwaters of

864-506: Is peculiarly elaborate. Known as the Badlands , it is a minutely dissected form with a relief of a few hundred feet. This is due to several causes: The central section of the Great Plains, between latitudes 42° and 36° , occupying eastern Colorado and western Kansas , is mostly a dissected fluviatile plain. That is, this section was once smoothly covered with a gently sloping plain of gravel and sand that had been spread far forward on

936-455: Is used: the climatic and vegetation regions are more impactful on human settlement than mere topography, and therefore the region is split into (from north to south), the taiga plains, boreal plains , aspen parkland , and prairie ecoregion regions. The northern section of the Great Plains, north of latitude 44° , includes eastern Montana , eastern Wyoming , most of North Dakota and South Dakota , southwestern Minnesota and portions of

1008-563: The American burying beetle (Nicrophorus americus), Salt Creek Tiger Beetle (Cinidela nevadica lincolniana), Great Plains Giant Tiger Beetle (Amblycheila chylindriformis), Microstylum morosum , Bean leaf beetle (Cerotoma trifurcata), Great Plains Camel Cricket (Daihinia brevipes), and the Great plains spittlebug (Lepyronia gibbosa). Some species in the Great plains have gone extinct in

1080-593: The Arikara , Mandan , Pawnee , and Wichita . Wars with the Ojibwe and Cree peoples pushed the Lakota (Teton Sioux) west onto the Great Plains in the mid- to late-17th century. The Shoshone originated in the western Great Basin and spread north and east into present-day Idaho and Wyoming. By 1500, some Eastern Shoshone had crossed the Rocky Mountains into the Great Plains. After 1750, warfare and pressure from

1152-689: The Central United States and Western Canada , encompassing: The term "Great Plains" is used in the United States to describe a sub-section of the even more vast Interior Plains physiographic division, which covers much of the interior of North America. It also has currency as a region of human geography , referring to the Plains Indians or the Plains states . In Canada the term is rarely used; Natural Resources Canada ,

1224-690: The Commission for Environmental Cooperation , a North American Free Trade Agreement (NAFTA) agency composed of 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

Department of Agriculture , administers the National Forests and National Grasslands, under a multiple-use concept. By law, the U.S. Forest Service must consider all resources, with no single resource emphasized to the detriment of others, including water, soil, grazing, timber harvesting, and minerals (mining and drilling), as well as recreation and conservation of fish and wildlife. Each individual state also administers state lands, typically smaller areas, for various purposes including conservation and recreation. Grasslands are among

Some species predominately associated with various river basins in the Great Plains include sturgeon chub ( Macrhybopsis gelida ), peppered chub ( Macrhybopsis tetranema ), prairie chub ( Macrhybopsis australis ), western silvery minnow ( Hybognathus argyritis ), plains minnow ( Hybognathus placitus ), smalleye shiner ( Notropis buccula ), Arkansas River shiner ( Notropis girardi ), Red River shiner ( Notropis bairdi ), Topeka shiner ( Notropis topeka ), plains topminnow ( Fundulus sciadicus ), plains killifish ( Fundulus zebrinus ), Red River pupfish ( Cyprinodon rubrofluviatilis ), and Arkansas darter ( Etheostoma cragini ). The great plains also has many invertebrate species living here both alive and extinct such as

1440-592: The New York–New Haven rail line at Westport, Connecticut , took eight days to clear. Transportation gridlock as a result of the storm was partially responsible for the creation of the first underground subway system in the United States, which opened nine years later in Boston. The New York Stock Exchange was closed for two days. A full two day weather related closure would not occur again until Hurricane Sandy in 2012. Similarly, telegraph infrastructure

The first known contact between Europeans and Indians in the Great Plains occurred in what is now Texas, Kansas, and Nebraska from 1540 to 1542 with the arrival of Francisco Vázquez de Coronado , a Spanish conquistador. In that same period, Hernando de Soto crossed

Efforts were made to push the snow into the Atlantic Ocean. Severe flooding occurred after the storm due to melting snow, especially in the Brooklyn area, which was susceptible to flooding because of its topography. Not all areas were notably affected by

1872-557: The Comanche were among the first to commit to a fully mounted nomadic lifestyle. This occurred by the 1730s, when they had acquired enough horses to put all their people on horseback. The real beginning of the horse culture of the plains began with the Pueblo Revolt of 1680 in New Mexico and the capture of thousands of horses and other livestock. In 1683 a Spanish expedition into Texas found horses among Native people. In 1690,

There is no region referred to as the "Great Plains" in the Atlas of Canada . In terms of human geography, the term prairie is more commonly used in Canada, and the region is known as the Canadian Prairies , prairie provinces or simply "the prairies". The North American Environmental Atlas , produced by

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

On March 13, New York City recorded a low of 6 °F (−14 °C), the coldest so late in the season, with the high rising to only 12 °F (−11 °C). In New York, neither rail nor road transport was possible anywhere for days, and drifts across

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

3456-468: 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

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

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

3672-760: 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

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

3816-436: 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

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

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

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

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,

4176-460: The snow reduced visibilities on the open plains to zero. People ventured from the safety of their homes to do chores, go to town, attend school, or simply enjoy the relative warmth of the day. As a result, thousands of people — including many schoolchildren — got caught in the blizzard. The death toll was 235, though some estimate 1,000. Teachers generally kept children in their schoolrooms. Exceptions nearly always resulted in disaster. This cold front

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

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

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

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

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

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
