Ellesmere Island
Ellesmere Island (; ) is Canada's northernmost and List of Canadian islands by area, third largest island, and the List of islands by area, tenth largest in the world. It comprises an area of , slightly smaller than Great Britain, and the total length of the island is . Lying within the Arctic Archipelago, Ellesmere Island is considered part of the Queen Elizabeth Islands. Cape Columbia at is the most northerly point of land in Canada and one of the most northern points of land on the planet (the most northerly point of land on Earth is the nearby Kaffeklubben Island of Greenland). The Arctic Cordillera mountain system covers much of Ellesmere Island, making it the most mountainous in the Arctic Archipelago. More than one-fifth of the island is protected as Quttinirpaaq National Park. In 2021, the population of Ellesmere Island was recorded at 144. There are three settlements: Alert, Nunavut, Alert, Eureka, Nunavut, Eureka, and Grise Fiord. Ellesmere Island is administered as ...

Quttinirpaaq National Park
Quttinirpaaq National Park is located on the northeastern corner of Ellesmere Island in the Qikiqtaaluk Region of Nunavut, Canada. It is the second most northerly park on Earth after Northeast Greenland National Park. In Inuktitut, Quttinirpaaq means "top of the world". It was established as Ellesmere Island National Park Reserve in 1988, and the name was changed to Quttinirpaaq in 1999, when Nunavut was created, and became a National parks of Canada, national park in 2000. The reserve covers , making it the List of national parks of Canada, second largest park in Canada, after Wood Buffalo National Park. The park is remarkable for its extensive glaciers and ice caps, desert-like conditions, and life forms that are uniquely adapted to the extreme Polar regions of Earth, polar environment. Only about 50 people visit the park each year. Landscape and weather The land is dominated by rock and ice. It is a polar desert with very little annual precipitation. Much of the highlands o ...

Smith Sound
Smith Sound (; ) is an Arctic sea passage between Greenland Greenland is an autonomous territory in the Danish Realm, Kingdom of Denmark. It is by far the largest geographically of three constituent parts of the kingdom; the other two are metropolitan Denmark and the Faroe Islands. Citizens of Greenlan ... and Nunavut's northernmost island, Ellesmere Island. It links Baffin Bay with Kane Basin and forms part of the Nares Strait. On the Canadian side it extends from Cape Sabine in the north to Cape Isabella in the south. On the Greenland side of the sound were the now abandoned settlements of Etah and Annoatok. History The first known visit to the area by Europeans was in 1616 when the '' Discovery'', captained by Robert Bylot and piloted by William Baffin, sailed into this region. The sound was originally named ''Sir Thomas Smith's Bay'' after the English diplomat Sir Thomas Smythe. By the 1750s it regularly appeared on maps as ''Sir Thomas Smith's Sound'', thou ...

Independence I Culture
Independence I was a culture of Paleo-Eskimos who lived in northern Greenland and the Canadian Arctic between 2400 and 1900 BC. There has been much debate among scholars on when Independence I culture disappeared, and, therefore, there is a margin of uncertainty with the dates. The culture is named after Independence Fjord, which is a fjord located in Peary Land. The Independence I people lived at the same time as the Saqqaq culture of southern Greenland. Independence I culture was followed by Independence II culture, which had a similar geographical extent, and lasted from the 8th century BC, roughly 600 years after the disappearance of Independence I. The Independence I occupation of northern Greenland appears to have been much more extensive than that of Independence II. Independence I alongside Saqqaq culture are considered to be the earliest known cultures in Greenland. The first Palaeo-Eskimo migrants are thought to have migrated from the Canadian High Arctic and have a con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleo-Eskimo
The Paleo-Eskimo meaning ''"old Eskimos"'', also known as, pre-Thule people, Thule or pre-Inuit, were the peoples who inhabited the Arctic region from Chukotka Autonomous Okrug, Chukotka (e.g., Chertov Ovrag) in present-day Russia across North America to Greenland before the arrival of the modern Inuit (formerly called Eskimo) and related cultures. The Early Paleo-Eskimo, first known Paleo-Eskimo cultures developed by 3900 to 3600 BCE, but were gradually displaced in most of the region, with the last one, the Dorset culture, disappearing around 1500 CE. Paleo-Eskimo groups included the Pre-Dorset; the Saqqaq culture of Greenland (2500–800 BCE); the Independence I culture, Independence I and Independence II cultures of northeastern Canada and Greenland (c. 2400–1800 BCE and c. 800–1 BCE); the Groswater culture, Groswater of Labrador, Nunavik, and Newfoundland (island), Newfoundland and the Dorset culture (500 BCE – 1400 CE), which spread across Arctic North America.

Isostatic Rebound
Post-glacial rebound (also called isostatic rebound or crustal rebound) is the rise of land masses after the removal of the huge weight of ice sheets during the last glacial period, which had caused isostatic depression. Post-glacial rebound and isostatic depression are phases of glacial isostasy (glacial isostatic adjustment, glacioisostasy), the deformation of the Earth's crust in response to changes in ice mass distribution. The direct raising effects of post-glacial rebound are readily apparent in parts of Northern Eurasia, Northern America, Patagonia, and Antarctica. However, through the processes of ''ocean siphoning'' and ''continental levering'', the effects of post-glacial rebound on sea level are felt globally far from the locations of current and former ice sheets.Milne, G.A., and J.X. Mitrovica (2008) ''Searching for eustasy in deglacial sea-level histories.'' Quaternary Science Reviews. 27:2292–2302. Overview During the last glacial period, much of northern ...

Sverdrup Basin Magmatic Province
The Sverdrup Basin Magmatic Province is a large igneous province located on Axel Heiberg Island and Ellesmere Island, Nunavut, Canada near the rifted margin of the Arctic Ocean at the end of Alpha Ridge. With an area of 550,110 km2, the Sverdrup Basin Magmatic Province forms part of the larger High Arctic Large Igneous Province and consists of flood basalts, dikes and sills which form two volcanic formations called the Ellesmere Island Volcanics and Strand Fiord Formation. The flood basalt lava flows are similar to those of the Columbia River Basalt Group in the U.S. states of Washington, Oregon and Idaho. See also * Ashton F.

Ellesmere Island Volcanics
The Ellesmere Island Volcanics are a Late Cretaceous volcanic group of volcanoes and lava flows in the Qikiqtaaluk Region of northern Ellesmere Island, Nunavut, Canada. Ellesmere Island Volcanics are part of the Arctic Cordillera. This volcanic province is among the northernmost volcanism on Earth. History Even though these volcanics are about 90 million years old, the volcanoes and cinder are still discernible. The volcanics of the Maskell Inlet Assemblage are mostly made up of tuffs, with smaller flows. Compositionally these are mostly andesite or undifferentiated andesite/basalt. The volcanics on Ellesmere Island has been uncertainly associated to both the early volcanic activity of the Iceland hotspot and the Alpha Ridge. The Ellesmere Island Volcanics are part of the High Arctic Large Igneous Province.

Canadian Shield
The Canadian Shield ( ), also called the Laurentian Shield or the Laurentian Plateau, is a geologic shield, a large area of exposed Precambrian igneous and high-grade metamorphic rocks. It forms the North American Craton (or Laurentia), the ancient geologic core of the North American continent. Glaciation has left the area with only a thin layer of soil, through which exposures of igneous bedrock resulting from its long volcanic history are frequently visible. As a deep, common, joined bedrock region in eastern and central Canada, the shield stretches north from the Great Lakes to the Arctic Ocean, covering over half of Canada and most of Greenland; it also extends south into the northern reaches of the continental United States. Geographical extent The Canadian Shield is a physiographic division comprising four smaller physiographic provinces: the Laurentian Upland, Kazan Region, Davis and James. The shield extends into the United States as the Adirondack Mountains ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
