Ellesmere Island

Ellesmere Island is Canada's northernmost and third largest island, and the tenth largest in the world. It comprises an area of 196,236 square kilometres (75,767 sq mi), slightly smaller than Great Britain, and the total length of the island is 830 kilometres (520 mi).

Geology
Ellesmere Island has three major geological regions. The Grant Land Highlands is a large belt of fold mountains which dominate the northern face of the island. It is part of the Franklinian mobile belt, a zone of volcanic and intrusive rock from the Cretaceous. South of this is the Greely-Hazen Plateau, a large tableland composed of sedimentary and volcanic rocks. Covering most of the island, the coastal sedimentary plateau is a succession of highly eroded sedimentary peaks which are part of the Franklinian Shield with an extension of the Canadian Shield (Igneous and metamorphic rocks from the Precambrian) in the island's southeastern corner. In addition, there are syntectonic clastics which comprise the Ellesmere Island Volcanics of the Sverdrup Basin Magmatic Province. A period of uplift and faulting prior to the Pleistocene epoch (>2.6 Ma) established the overall features of the island. Additional uplift occurred due to isostatic rebound following the Last Glacial Period. Land features were then shaped by erosion from glacial ice, meltwaters, and scouring by sea ice. ==History==
History
It is believed that each of the pre-contact peoples who migrated through the High Arctic approached Ellesmere Island from the south and west. They were able to travel along Ellesmere's coasts or overland to Nares Strait, and some of them crossed the strait to populate Greenland. The archaeological record of past Arctic cultures is quite complete, as artifacts deteriorate very slowly. Items exposed to the cold, dry winds become naturally freeze-dried while items that become buried are preserved in the permafrost. Artifacts are in a similar condition to when they were left or lost, and settlements abandoned thousands of years ago can be seen much as they were the day their inhabitants left. From these sites and artifacts, archaeologists have been able to construct a history of these cultures. However, the research is incomplete and only a small proportion of the details of excavations have been published. Small tool cultures The Arctic Small Tool tradition peoples ( Paleo-Eskimos) in the High Arctic had small populations organized as hunting bands, spread from Axel Heiberg Island to the northern extremity of Greenland, where the Independence I culture was active from 2700 BCE. On Ellesmere, they chiefly hunted in the Eureka Upland and the Hazen Plateau. Six different small-tool cultures have been identified at the Smith Sound region: Independence I, Independence I / Saqqaq, Pre-Dorset, Saqqaq, early Dorset, and late Dorset. They chiefly hunted muskoxen: more than three-quarters of their known archaeological sites on Ellesmere are located in the island's interior and their winter dwellings were skin tents, suggesting a need for mobility to follow the herds. There is evidence at Lake Hazen of a trade network , including soapstone lamps (qulliq) from Greenland and incised lance heads from cultures to the south. Thule culture (brown) and expansion of the Thule (green), The Thule moved into the High Arctic at the time of a warming trend, c. 1000 CE. Their major population centre was the Smith Sound area (on both the Ellesmere and Greenland sides) due to its proximity to polynyas and its position on transportation routes. From settlements at Smith Sound, the Thule sent summer hunting parties to harvest marine mammals in Nansen Strait. Their summer camps are evidenced by tent rings as far north as Archer Fiord, with clusters of stone dwellings around Lady Franklin Bay and at Lake Hazen which suggest semi-permanent occupations. The Thule genetically and culturally completely replaced the Dorset some time after 1300 CE. The Thule displaced the small-tool cultures, having a number of technological advantages which notably included effective weapons, kayaks and umiaks for hunting marine mammals, and sled dogs for surface transport and pursuit. The Thule also had an extensive trade network, evidenced by meteoritic iron from Greenland which was exported through Ellesmere Island to the rest of the archipelago and to the North American mainland. More than fifty Norse artifacts have been found in Thule archaeological sites on the Bache Peninsula, including pieces of chain mail. It is uncertain if Ellesmere Island was directly visited by Norse Greenlanders who sailed from the south or if the items were traded through a network of middlemen. It is also possible the items may have been taken from a shipwreck. A bronze set of scales discovered in western Ellesmere Island has been interpreted as indicating the presence of a Norse trader in the region. The Norse artifacts date from c. 1250 to 1400 CE. Between 1400 and 1600 CE, the Little Ice Age developed and conditions for hunting became increasingly difficult, forcing the Thule to withdraw from Ellesmere and the other northern islands of the archipelago. The Thule who remained in northern Greenland became isolated, specialized at hunting a diminishing number of game animals, and lost the ability to make boats. Thus, the waters around Ellesmere were not navigated again until the arrival of large European vessels after 1800. Early European exploration Much of the initial phase of European exploration of the North American Arctic was centred on a search for the Northwest Passage and undertaken by Britain. The 1616 expedition of William Baffin were the first Europeans to record sighting the then-unnamed Ellesmere Island (Baffin named Jones and Smith Sounds on the island's south and southeast coasts). However, the onset of the Little Ice Age interrupted the progress of explorations for two centuries. In 1818, an ice jam in Baffin Bay broke, allowing European vessels access to the High Arctic (whalers had been active in Davis Strait, about southeast of Ellesmere, since 1719). Baffin Bay was then navigable in the summers due to the presence of an ice dam in Smith Sound, which prevented Arctic drift ice from flowing south. The other channels of the archipelago remained congested with ice. That year, John Ross led the first recorded European expedition to Cape York, at which time there were reportedly only 140 Inughuit. (The Inughuit of North Greenland, the Kalaallit of West Greenland, and Inuit of the archipelago are descendants of the Thule culture, which had diverged during the isolation imposed by the Little Ice Age.) Knowledge of Ellesmere persisted in the oral histories of the Inuit of Baffin Island and the Inughuit of northern Greenland, who each called it . Euro-American exploration and contact The search for Franklin's lost expedition – also searching for the Northwest Passage and to establish claims to the Far North – involved more than forty expeditions to the High Arctic over two decades, and represented the peak period of Euro-American Arctic exploration. Edward Augustus Inglefield led an 1852 expedition which surveyed the coastlines of Baffin Bay and Smith Sound, being stopped by ice in Nares Strait. He named Ellesmere Island for the president of the Royal Geographical Society (1849–1852), Francis Egerton, 1st Earl of Ellesmere. The Second Grinnell expedition (1853–1855) made slightly further progress before becoming trapped in the ice. Over two winters the expedition charted both sides of Kane Basin to about 80°N, from where Elisha Kent Kane claimed to have sighted the conjectured Open Polar Sea. During this period, as the Little Ice Age abated and the hunting of marine mammals became more feasible again, Indigenous peoples began to return to Ellesmere Island. The most well-known of these migrations in both Inuit and European accounts is the journey of Qitlaq, who led a group of Inuit families from Baffin Island to northwestern Greenland, via Ellesmere Island, in the 1850s. This journey reestablished contact between Inuit who had been separated for two centuries and reintroduced vital technologies to the Inughuit. Other groups followed and by the 1870s Inuit were living on Ellesmere Island and had regular contact with those on the neighbouring islands. Contact between Inuit and Europeans or Americans was often indirect, as the Inuit happened upon shipwrecks or abandoned base camps which provided wood and metal resources. European goods were also obtained through inter-group trade. Long-term contact began in the 1800s through whaling stations and trading posts, which frequently relocated. Euro-American expeditions employed Inughuit, Inuit and west Greenlander guides, hunters and labourers, gradually blending their knowledge with European technology to conduct effective exploration. off Cape Prescott in 1875 British and United States Arctic expeditions had been interrupted for some years due to the priorities of the Crimean War and the American Civil War, respectively. By about 1860, the focus of Arctic exploration had shifted to the North Pole. As earlier attempts at the pole via Svalbard or eastern Greenland had reached impasses, numerous expeditions came to Ellesmere Island to pursue the route through Nares Straight. in Grinnel Land, May 1883 The Lady Franklin Bay Expedition, a United States expedition, led by Adolphus Greely in 1881 crossed the island from east to west, establishing Fort Conger in the northern part of the island. The Greely expedition found fossil forests on Ellesmere Island in the late 1880s. Stenkul Fiord was first explored in 1902 by Per Schei, a member of Otto Sverdrup's 2nd Norwegian Polar Expedition. The Ellesmere Ice Shelf was documented by the British Arctic Expedition of 1875–76, in which Lieutenant Pelham Aldrich's party went from Cape Sheridan () west to Cape Alert (), including the Ward Hunt Ice Shelf. In 1906 Robert Peary led an expedition in northern Ellesmere Island, from Cape Sheridan along the coast to the western side of Nansen Sound (93°W). During Peary's expedition, the ice shelf was continuous; it has since been estimated to have covered . The ice shelf broke apart in the 20th century, presumably due to climate change. Establishment of Canadian sovereignty In 1880, the British Arctic Territories were transferred to Canada. Canada did little to solidify its legal possession of the islands until prompted by foreign action in 1902–03: Otto Sverdrup claimed the Sverdrup Islands, three islands west of Ellesmere, for Norway, the Alaska boundary dispute was settled against Canada's interests, and Roald Amundsen set out to sail the Northwest Passage. To establish an official government presence in the Far North, the North-West Mounted Police (NWMP) were sent on sovereignty patrols. A NWMP detachment sailed to the Arctic whaling stations in 1903, where they forbade whalers from killing muskox or trading skins, in order to prevent over hunting and protect the ability of Inuit to sustain themselves. In 1904 a NWMP detachment sailed to Cape Herschel at the east end of Sverdrup Pass, where they could intercept hunters accessing the interior of Ellesmere. While the fur trade was brought under control, American exploration parties to the Far North had acted with autonomy and intensively hunted terrestrial mammals to sustain their expeditions. Peary's parties had heavily hunted muskoxen on Ellesmere and had nearly brought the extinction of caribou in northern Greenland; the Crocker Land Expedition (1913–1916) also extensively hunted muskoxen. In response to these and other trespasses, the government amended the Northwest Game Act to prohibit the killing of muskoxen except for Native inhabitants who otherwise faced starvation. In 1920, the government learned that Inughuit from Greenland had been annually visiting Ellesmere Island for polar bear and muskox hunting – in violation of Canadian law – and selling the skins at Knud Rasmussen's trading post at North Star Bay (known as Thule). The Danish government stated that North Greenland was a "no man's land" outside their administration and Rasmussen, as the de facto sole authority, refused to stop the trade, which the Inughuit needed to support themselves. In response, Royal Canadian Mounted Police (RCMP) detachments were established on Ellesmere Island at Craig Harbour in 1922 and at Bache Post in 1926, positioned to guard the coastal and overland routes to the hunting grounds on the western side of Ellesmere. In addition to intercepting illegal hunting and fur-trading, the RCMP conducted patrols and encouraged the Inuit to maintain their traditional lifestyle. The posts were closed in the mid-1930s, after the sovereignty issues had been settled. ==Geography==
Geography
Ellesmere Island is the northernmost island of the Arctic Archipelago in Canada's Far North and one of the world's northernmost land masses. It is exceeded in this regard only by neighbouring Greenland, which extends about closer to the north pole. Ellesmere's northernmost point, Cape Columbia (at ), is less than from the north pole, while its southern coasts at 77°N are well within the Arctic Circle. Ellesmere has the highest and longest mountain ranges in eastern North America and is the most mountainous island in the Arctic Archipelago. It has over half of the archipelago's ice cover, with ice caps and glaciers across 40% of its surface. Its extensive coastline includes some of the world's longest fiords. To the west, Ellesmere is separated from Axel Heiberg Island by Nansen and Eureka Sounds, the latter of which narrows to . Devon Island is to the south across Jones Sound; at the west end of the sound, they are separated by North Kent Island and two channels which narrow to . Greenland is to the east across Nares Strait; the strait narrows to at Cape Isabella on Smith Sound and further north narrows to at Robeson Channel. These channels and straits typically freeze over in winter, though winds and currents leave pockets of open water (temporary leads and persistent polynyas) in Nares Strait. To the north of Ellesmere is the Arctic Ocean, with Lincoln Sea to the northeast. Protected areas More than one-fifth of the island is protected as Quttinirpaaq National Park (formerly Ellesmere Island National Park Reserve), which includes seven fjords and a variety of glaciers, as well as Lake Hazen, North America's largest lake north of the Arctic Circle. The highest mountain in Nunavut, Barbeau Peak (), is located in the British Empire Range on Ellesmere Island. The most northern mountain range in the world, the Challenger Mountains, is located in the northeast region of the island. The northern lobe of the island is called Grant Land. in Tanquary Fiord The Arctic willow is the only woody species to grow on Ellesmere Island.) found that the ponds had been permanent and relatively stable for several millennia until experiencing ecological changes associated with warming, beginning around 1850 and accelerating in the early 2000s. During the 23-year study period, an ecological threshold was crossed as several of the study ponds had completely desiccated while others had very reduced water levels. In addition, the wetlands surrounding the ponds were severely affected and dried vegetation could be easily burned. While non-eusocial, the Arctic woolly bear moth (Gynaephora groenlandica) can also be found on Ellesmere Island. While this species generally has a 10-year life cycle, its life is known to extend to up to 14 years at both the Alexandra Fiord lowland and Ellesmere Island. Earth's magnetism In 2015, the Earth's geomagnetic north pole was located at approximately , on Ellesmere Island. It is forecast to remain on Ellesmere Island in 2020, shifting to . the north geomagnetic pole (the south pole of the earth's magnetic field) is located on the island at . ==Population==
Population
, June 1988|upright All groups occupying the island settled on the coast, particularly those relying on maritime resources, while modern-era government-funded settlements were initially supplied by sea. In 2021, the population of Ellesmere Island was recorded as 144. There are three settlements on Ellesmere Island: Alert (permanent pop. 0, but home to a small temporary population), Eureka (permanent pop. 0), and Grise Fiord (pop. 144). With the end of the Cold War and the advent of new technologies allowing for remote interpretation of data, the overwintering population has been reduced to 62 civilians and military personnel as of 2016. Eureka Eureka (the third northernmost settlement in the world) consists of three areas: Eureka Aerodrome, which includes Fort Eureka (the quarters for military personnel maintaining the island's communications equipment); the Environment and Climate Change Canada Weather Station; and the Polar Environment Atmospheric Research Laboratory (PEARL), formerly the Arctic Stratospheric Ozone (AStrO) Observatory. Eureka has the lowest average annual temperature and least precipitation of any weather station in Canada. Grise Fiord in 1952–55. This was during Canada's controversial High Arctic relocation program |upright Grise Fiord (Inuktitut: , Romanized: , lit. "place that never thaws") is an Inuit hamlet that, despite a population of only 144, Grise Fiord is cradled by the Arctic Cordillera mountain range. ==Transportation==
Transportation
Transportation along coastal waters has been historically important for hunting and trade, whether on the sea ice or in small boats. The ice foot, a belt of level and secure ice around the shoreline between the high and low water marks, can be used from mid-September to July. In contrast, the pack ice does not stabilize and freeze fast until February, and presents a much rougher surface for travel. The navigation season for seagoing vessels is from late July to September, but is often considered treacherous due to currents, persistent shore ice, sea ice, and massive icebergs calved off of the many glaciers. September also marks a change in the weather with regular fog and the beginning of the autumn storm season. ==In popular culture==
