The Canadian Shield, also called 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, 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 United States.
Ellesmere Island is Canada's northernmost and third largest island, and the tenth largest in the world. It comprises an area of 196,236 km2 (75,767 sq mi), slightly smaller than Great Britain, and the total length of the island is 830 km (520 mi).
The Arctic Archipelago, also known as the Canadian Arctic Archipelago, is an archipelago lying to the north of the Canadian continental mainland, excluding Greenland and Iceland.
Baffin Bay, located between Baffin Island and the west coast of Greenland, is defined by the International Hydrographic Organization as a marginal sea of the Arctic Ocean. It is sometimes considered a sea of the North Atlantic Ocean. It is connected to the Atlantic via Davis Strait and the Labrador Sea. The narrower Nares Strait connects Baffin Bay with the Arctic Ocean. The bay is not navigable most of the year because of the ice cover and high density of floating ice and icebergs in the open areas. However, a polynya of about 80,000 km2 (31,000 sq mi), known as the North Water, opens in summer on the north near Smith Sound. Most of the aquatic life of the bay is concentrated near that region.
Devon Island is an island in Canada and the largest uninhabited island in the world. It is located in Baffin Bay, Qikiqtaaluk Region, Nunavut, Canada. It is one of the largest members of the Arctic Archipelago, the second-largest of the Queen Elizabeth Islands, Canada's sixth-largest island, and the 27th-largest island in the world. It has an area of 55,247 km2 (21,331 sq mi). The bedrock is Precambrian gneiss and Paleozoic siltstones and shales. The highest point is the Devon Ice Cap at 1,920 m (6,300 ft) which is part of the Arctic Cordillera. Devon Island contains several small mountain ranges, such as the Treuter Mountains, Haddington Range and the Cunningham Mountains. The notable similarity of its surface to that of Mars has attracted interest from scientists.
The Victoria Cross Ranges are a set of mountain ranges in the Canadian Rockies, located to the northwest of Jasper. Of the 19 peaks contained within this range, five are named after Canadian recipients of the Victoria Cross. The area of the ranges is 678 square kilometres (262 sq mi).
Devon Energy Corporation is an energy company engaged in hydrocarbon exploration in the United States. It is organized in Delaware and its corporate operative headquarters are in the 50-story Devon Energy Center in Oklahoma City, Oklahoma. Its primary operations are in the Barnett Shale STACK formation in Oklahoma, Delaware Basin, Eagle Ford Group, and the Rocky Mountains.
The Juneau Icefield is an ice field located just north of Juneau, Alaska, continuing north through the border with British Columbia, extending through an area of 3,900 square kilometres (1,500 sq mi) in the Coast Range ranging 140 km (87 mi) north to south and 75 km (47 mi) east to west. The icefield is the source of many glaciers including the Mendenhall Glacier and the Taku Glacier. The icefield is home to over 40 large valley glaciers and 100 smaller ones. The Icefield serves as a tourist attraction with many travellers flown in by helicopter for quick walks on the 240-to-1,400-metre deep ice and the massive, awe-inspiring moist crevasses. The icefield, like many of its glaciers, reached its maximum glaciation point around 1700 and has been in retreat since. In fact, of the icefield's 19 notable glaciers, the Taku Glacier is the only one presently advancing. Much of the icefield is contained within the Tongass National Forest. Since 1948, the Juneau Icefield Research Program has monitored glaciers of the Juneau Icefield. On the west side of the icefield, from 1946-2009, the terminus of the Mendenhall Glacier has retreated over 700 metres (0.43 mi).
The Anti-Atlas, also known as Lesser Atlas or Little Atlas, is a mountain range in Morocco, a part of the Atlas Mountains in the northwest of Africa. The Anti-Atlas extends from the Atlantic Ocean in the southwest toward the northeast, to the heights of Ouarzazate and further east to the city of Tafilalt, altogether a distance of approximately 500 km. The range borders on the Sahara to the south.
The Arctic Cordillera is a terrestrial ecozone in northern Canada characterized by a vast, deeply dissected chain of mountain ranges extending along the northeastern flank of the Canadian Arctic Archipelago from Ellesmere Island to the northeasternmost part of the Labrador Peninsula in northern Labrador and northern Quebec, Canada. It spans most of the eastern coast of Nunavut with high glaciated peaks rising through ice fields and some of Canada's largest ice caps, including the Penny Ice Cap on Baffin Island. It is bounded to the east by Baffin Bay, Davis Strait and the Labrador Sea while its northern portion is bounded by the Arctic Ocean.
The Stikine Ranges are a group of mountain ranges and mountainous plateaus in northwestern British Columbia, Canada. They are the northernmost subdivision of the Cassiar Mountains and among the least explored and most undeveloped parts of the province.
The Cunningham Mountains are a small mountain range on the southeastern coast of Devon Island, Nunavut, Canada. The Cunningham Mountains are part of the Devon Ice Cap which forms part of the Arctic Cordillera mountain range.
The Inglefield Mountains are a mountain range in southeastern Ellesmere Island, Nunavut, Canada. The mountain range is mostly covered by ice fields, with granitic nunataks reaching a height of 1,500 m (4,921 ft) above sea level. Rocky cliffs border the coastal areas. Like most other mountain ranges in the Canadian Arctic, the Inglefield Mountains are part of the Arctic Cordillera.
The Scoresby Hills, also called the Scoresby Mountains, are a mountain range on the east coast of Bathurst Island, Nunavut, Canada. It consists of low hills which in turn form part of the Arctic Cordillera mountain system.
Piper Pass is a mountain pass in the United States Range, Nunavut, Canada.
The Nass Ranges are a mountain range north of the Skeena River, west of Hazelton, and northeast of Terrace, British Columbia, Canada. It is associated with the Hazelton Mountains, which in turn form part of the Interior Mountains.
The Pembroke Range is a small mountain range in southwestern British Columbia, Canada, between Loughborough Inlet and Phillips Arm. It has an area of 75 km2 and is a subrange of the Pacific Ranges which in turn form part of the Coast Mountains.
Dundas Harbour is an abandoned settlement in the Qikiqtaaluk Region, Nunavut, Canada. It is located on Devon Island at the eastern shore of the waterway also named Dundas Harbour. Baffin Bay's Croker Bay is immediately to the west.
On the continent of Antarctica, the Aramis Range is the third range south in the Prince Charles Mountains, situated 11 miles southeast of the Porthos Range and extending for about 30 miles in a southwest–northeast direction. It was first visited in January 1957 by Australian National Antarctic Research Expeditions (ANARE) southern party led by W.G. Bewsher, who named it for a character in Alexandre Dumas' novel The Three Musketeers, the most popular book read on the southern journey.
