Plano Culture
The Plano cultures is a name given by archaeologists to a group of disparate hunter-gatherer communities that occupied the Great Plains area of North America during the Paleo-Indian or Archaic period. Distinguishing characteristics The Plano cultures are characterised by a range of unfluted projectile point tools collectively called Plano points and like the Folsom people generally hunted ''Bison antiquus'', but made even greater use of techniques to force stampedes off of a cliff or into a constructed corral. Their diets also included pronghorn, elk, deer, raccoon, and coyote. To better manage their food supply, they preserved meat in berries and animal fat and stored it in containers made of hides. History The Plano cultures existed in the North American Arctic during the Paleo-Indian or Archaic period between 9000 BCE and 6000 BCE. The Plano cultures originated in the plains, but extended far beyond, from the Atlantic coast to modern-day British Columbia and as far ...

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 Man ...

9000 BCE
The 9th millennium BC spanned the years 9000 BC to 8001 BC (11 to 10 thousand years ago). In chronological terms, it is the first full millennium of the current Holocene epoch that is generally reckoned to have begun by 9700 BC (11.7 thousand years ago). It is impossible to precisely date events that happened around the time of this millennium and all dates mentioned here are estimates mostly based on geological and anthropological analysis, or by radiometric dating. In the Near East, especially in the Fertile Crescent, the transitory Epipalaeolithic age was gradually superseded by the Neolithic with evidence of agriculture across the Levant to the Zagros Mountains in modern-day Iran. The key characteristic of the Neolithic is agricultural settlement, albeit with wooden and stone tools and weapons still in use. It is believed that agriculture had begun in China by the end of the millennium. Elsewhere, especially in Europe, the Palaeolithic continued. Global environment In t ...

Jurgens Site
The Jurgens Site is a Paleo-Indian site located near Greeley in Weld County, Colorado. While the site was used primarily to hunt and butcher '' bison antiquus'', there is evidence that the Paleo-Indians also gathered plants and seeds for food about 7,000 to 7,500 BC. Geography The site is located on a South Platte River terrace in northeastern Colorado, east of Greeley near the town of Kersey.Gibbon, Ames, p. 404. There are three sites located nearby; The Frazier site is away and the Dent site is southwest. History Paleo-Indian Paleo-Indians were primarily hunters of large mammals, such as the Bison antiquus,Griffin-Pierce, 130. during a transitional period from Ice Age to Ice Age summer. As the climate warmed, glacial run-off created lakes and savannas. At the end of the summer period the land became drier, food was not as abundant, and they became extinct. People adapted by hunting smaller mammals and gathering wild plants to supplement their diet. The items f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cody, Wyoming
Cody is a city in Northwest Wyoming and the seat of government of Park County, Wyoming, United States. It is named after Colonel William Frederick "Buffalo Bill" Cody for his part in the founding of Cody in 1896. The population was 10,066 at the 2020 census. Cody is served by Yellowstone Regional Airport. Geography Cody is located at (44.523244, −109.057109).

The other two are west of town; one allows access to the East Gate of Yel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cody Complex
The Cody complex is a Paleo-Indian culture group first identified at a bison antiquus kill site near Cody, Wyoming in 1951. Points possessing characteristics of Cody Complex flaking have been found all across North America from Canada to as far south as Oklahoma and Texas. The tradition is generally attributed to the North American, primarily in the High Plains portion of the American Great Plains. The discovery of the Cody complex broadened the understanding of late Paleo-Indian cultural traditions beyond the Folsom tradition. Most Cody complex sites were bison antiquus kill and butcher sites, and sometime campsites.Gibbon, Guy E.; Ames, Kenneth M''Archaeology of Prehistoric Native America: An Encyclopedia''. 1998. , pp. 168-169. The sites are distinguished by their campsites, tools and butchering process. The tools, dated between about 6,000 and 8,000 BC, include Cody knives and Scottsbluff and diamond-shaped Eden projectile points.Shortt, Mack W''Record of Early Peopl ...

Agate Basin Site
The Agate Basin Site is a Paleoindian archeological site in Niobrara County, Wyoming. The location was discovered by William H. Spencer of Spencer, Wyoming in 1916, who found well-preserved stone blades and points in Moss Agate Arroyo. In 1941 Spencer mentioned the find to Robert E. Frison, a deputy game warden at Newcastle, who visited the site and contacted Dr. Frank H.H. Roberts of the Bureau of American Ethnology at the Smithsonian Institution. Roberts visited the site in 1942, but it would not be until 1959 that a full investigation began by the University of Wyoming on what proved to be a buffalo kill site. Further investigation took place under the direction of Dr. George C. Frison. The site was listed on the National Register of Historic Places The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance ...

Lanceolate
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bison
Bison are large bovines in the genus ''Bison'' (Greek: "wild ox" (bison)) within the tribe Bovini. Two extant and numerous extinct species are recognised. Of the two surviving species, the American bison, ''B. bison'', found only in North America, is the more numerous. Although colloquially referred to as a buffalo in the United States and Canada, it is only distantly related to the true buffalo. The North American species is composed of two subspecies, the Plains bison, ''B. b. bison'', and the wood bison, ''B. b. athabascae'', which is the namesake of Wood Buffalo National Park in Canada. A third subspecies, the eastern bison (''B. b. pennsylvanicus'') is no longer considered a valid taxon, being a junior synonym of ''B. b. bison''. References to "woods bison" or "wood bison" from the eastern United States refer to this subspecies, not ''B. b. athabascae'', which was not found in the region. The European bison, ''B. bonasus'', or wisent, or zubr, or colloquially Europe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boreal Woodland Caribou
The boreal woodland caribou (''Rangifer tarandus caribou''; but subject to a recent taxonomic revision. See Reindeer: taxonomy), also known as woodland caribou, boreal forest caribou and forest-dwelling caribou, is a North American subspecies of reindeer (or caribou in North America) found only in Canada. Unlike the Porcupine caribou and barren-ground caribou, boreal woodland caribou are primarily (but not always) sedentary. In their 2012 report entitled "Recovery Strategy for the Woodland Caribou (Rangifer tarandus caribou), Boreal population, in Canada", Environment Canada and SARA refer to the woodland caribou as "boreal caribou". "Woodland Caribou (''Rangifer tarandus caribou''), Boreal population herein referred to as "boreal caribou", assessed in May 2002 as threatened by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). The boreal woodland caribou is the third largest of the caribou ecotypes after Selkirk Mountain caribou and Osborn's caribou (see Re ...

Barren-ground Caribou
The barren-ground caribou (''Rangifer tarandus groenlandicus''; but subject to a recent taxonomic revision. See Reindeer: Taxomony.) is a subspecies of the reindeer (or the caribou in North America) that is found in the Canadian territories of Nunavut and the Northwest Territories, in northern Alaska and in south-western, Greenland. It includes the Porcupine caribou of Yukon and Alaska.Cronin, M. A., M. D. Macneil, and J. C. Patton (2005). ''Variation in Mitochondrial DNA and Microsatellite DNA in caribou (Rangifer tarandus) in North America.'' Journal of Mammalogy 86(3): 495–505. The barren-ground caribou is a medium-sized caribou, smaller and lighter-colored than the boreal woodland caribou, with the females weighing around and the males around . However, on some of the smaller islands, the average weight may be less. The large migratory herds of barren-ground caribou take their names from the traditional calving grounds, such as the Ahiak herd, the Baffin Island herds, th ...

Glacial Lake Agassiz
Lake Agassiz was a large glacial lake in central North America. Fed by glacial meltwater at the end of the last glacial period, its area was larger than all of the modern Great Lakes combined. First postulated in 1823 by William H. Keating, it was named by Warren Upham in 1879 after Louis Agassiz, when Upham recognized that the lake was formed by glacial action. Geological progression During the last ice age, northern North America was covered by an ice sheet, which alternately advanced and retreated with variations in the climate. This continental ice sheet formed during the period now known as the Wisconsin glaciation, and covered much of central North America between 30,000 and 10,000 years ago. As the ice sheet disintegrated, its meltwaters created an immense proglacial lake. Around 13,000 years ago, this lake came to cover much of what are now southeastern Manitoba, northwestern Ontario, northern Minnesota, eastern North Dakota, and Saskatchewan. At its greatest exte ...
