Bluefish Caves
Bluefish Caves is an archaeological site in Yukon, Canada, located southwest of the Vuntut Gwichin community of Old Crow, from which a jaw bone of a Yukon horse has been radiocarbon dated to 24,000 years before present (BP). There are three small caves in the area. Context Bluefish Cave was initially known to the local First Nations, but was popularized by a fishing expedition in 1976, and later by researchers. This site is made up of three small caves, ranging from . The first cave contains various animal bones that appear to have been dragged there by predators; findings of tool marks and some tools themselves point to a human presence. The Old Crow Flats, another important area with early human presence, are located about 75 km northeast of the Bluefish Caves. Dating The site was excavated by archaeologist Jacques Cinq-Mars between 1977 and 1987, and the initial radiocarbon dating suggested an age of 24,000 before present (BP). This was considered controversial as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Last Glacial Maximum
The Last Glacial Maximum (LGM), also referred to as the Late Glacial Maximum, was the most recent time during the Last Glacial Period that ice sheets were at their greatest extent. Ice sheets covered much of Northern North America, Northern Europe, and Asia and profoundly affected Earth's climate by causing drought, desertification, and a large drop in sea levels. Based on changes in position of ice sheet margins dated via terrestrial cosmogenic nuclides and radiocarbon dating, growth of ice sheets commenced 33,000 years ago and maximum coverage was between 26,500 years and 19–20,000 years ago, when deglaciation commenced in the Northern Hemisphere, causing an abrupt rise in sea level. Decline of the West Antarctica ice sheet occurred between 14,000 and 15,000 years ago, consistent with evidence for another abrupt rise in the sea level about 14,500 years ago. Glacier fluctuations around the Strait of Magellan suggest the peak in glacial surface area was constrained to betwee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography Of Yukon
Yukon is in the northwestern corner of Canada and is bordered by Alaska and the Northwest Territories. The sparsely populated territory abounds with natural scenic beauty, with snowmelt lakes and perennial white-capped mountains, including many of Canada's highest mountains. The territory's climate is Arctic climate, Arctic in territory north of Old Crow, Yukon, Old Crow, Subarctic climate, subarctic in the region, between Whitehorse, Yukon, Whitehorse and Old Crow, and humid continental climate south of Whitehorse and in areas close to the British Columbia border. Most of the territory is boreal forest with tundra being the main vegetation zone only in the extreme north and at high elevations. The territory is about the shape of a right triangle, bordering the United States, American state of Alaska to the west, the Northwest Territories to the east and British Columbia to the south. Yukon covers 482,443 km2, of which 474,391 km2 is land and 8,052 km2 is water, maki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prehistory Of The Arctic
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archaeological Sites In Yukon
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic until the advent of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pendejo Cave
Pendejo Cave is a geological feature and archaeological site located in southern New Mexico about 20 miles east of Orogrande. Archaeologist Richard S. MacNeish claimed that human occupation of the cave pre-dates by tens of thousands of years the Clovis Culture, traditionally believed to be one of the oldest if not the oldest culture in the Americas. Description Pendejo is a relatively small cave, only 5 meters wide, 12 meters deep, and having a maximum height of 3 meters. It is below the rim of an escarpment, facing north, and about above the canyon floor. The cave is located at an elevation of amidst the sparse desert vegetation of the Chihuahua Desert. A slightly more mesic habitat is found at the foot of the cliffs. Pendejo is a Spanish word and literally means ''"a pubic hair"'', but in Mexico it can also be a vulgar insult to someone's intelligence. Archaeological history Pendejo Cave was discovered in 1978, and twelve years later, in early 1990, the first archaeologic ...

Beringia
Beringia is defined today as the land and maritime area bounded on the west by the Lena River in Russia; on the east by the Mackenzie River in Canada; on the north by 72 degrees north latitude in the Chukchi Sea; and on the south by the tip of the Kamchatka Peninsula. It includes the Chukchi Sea, the Bering Sea, the Bering Strait, the Chukchi and Kamchatka Peninsulas in Russia as well as Alaska in the United States and the Yukon in Canada. The area includes land lying on the North American Plate and Siberian land east of the Chersky Range. At certain times in prehistory, it formed a land bridge that was up to wide at its greatest extent and which covered an area as large as British Columbia and Alberta together, totaling approximately . Today, the only land that is visible from the central part of the Bering land bridge are the Diomede Islands, the Pribilof Islands of St. Paul and St. George, St. Lawrence Island, St. Matthew Island, and King Island.

Prehistoric Migration And Settlement Of The Americas From Asia
The settlement of the Americas began when Paleolithic hunter-gatherers entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the Last Glacial Maximum (26,000 to 19,000 years ago). These populations expanded south of the Laurentide Ice Sheet and spread rapidly southward, occupying both North and South America, by 12,000 to 14,000 years ago. The earliest populations in the Americas, before roughly 10,000 years ago, are known as Paleo-Indians. Indigenous peoples of the Americas have been linked to Siberian populations by linguistic factors, the distribution of blood types, and in genetic composition as reflected by molecular data, such as DNA. While there is general agreement that the Americas were first settled from Asia, the pattern of migration and the place(s) of origin in Eurasia of the peoples who migrated to the Americas remain unclea ...

Old Crow, Yukon
Old Crow is a community in the Canadian territory of Yukon. Located in a periglacial environment, the community is situated on the Porcupine River in the far northern part of the territory. Old Crow is the only Yukon community that cannot be reached by motor vehicle, requiring visitors to fly in to Old Crow Airport. It is a dry community. Old Crow is also the northernmost non-Inuit community in North America, and the only such community situated north of the Arctic Circle. History A large number of apparently human modified animal bones have been discovered in the Old Crow area, notably at Bluefish Caves, about south, and the Old Crow Flats, located about south, that have been dated to 25,000-40,000 years ago by carbon dating, several thousand years earlier than generally accepted human habitation of North America. An Indigenous chief named Deetru` K`avihdik, literally "Crow-May-I-Walk", helped settle a community here around the 1870s and the town was named after him. Th ...

Jacques Cinq-Mars
Jacques Cinq-Mars Born: 1941/42 (died 27 November 2021, aged 79) was a Canadian archaeologist specializing in Canada, especially Yukon. Cinq-Mars excavated the Bluefish Caves site in the Old Crow area from 1977 to 1987. His careful research showed the presence of humans in the Americas long before Clovis. His dates for the site are around 24,000 BP. Cinq-Mars began his work in the Old Crow area early in the 1970s. Although the Clovis-first hypothesis has substantially fallen out of favor, some archaeologists question the 24,000 BP date for human presence at Blue Fish Caves.Kathryn E. Krasinski and John C.

Old Crow Flats
Old Crow Flats (''Van Tat'' in the Gwichʼin language) is a wetland complex in northern Yukon, Canada along the Old Crow River. It is north of the Arctic Circle and south of the Beaufort Sea, and is nearly surrounded by mountains. Site The site is protected by the Yukon Wildlife Ordinance and Migratory Birds Convention Act. It was identified as part of the International Biological Program inventory, and was designated a wetland of international importance via the Ramsar Convention on May 24, 1982. The habitat is an important breeding area for aquatic mammals and peregrine falcons, is used for summer moulting by waterfowl, and is an autumn staging site for various species of birds. For these reasons, it is considered an Important Bird Area. Per the Vuntut Gwitchin Final Agreement, the southern extent of Old Crow Flats (approximately 7,785 km2) is classified as a ''Special Management Area'' by the Yukon Government; the northern portion is now part of Vuntut National Park.
