The Queen Elizabeth Islands are the northernmost cluster of islands in Canada's Arctic Archipelago, split between Nunavut and the Northwest Territories in Northern Canada. The Queen Elizabeth Islands contain approximately 14% of the global glacier and ice cap area. The southern islands are called the Parry Islands or Parry Archipelago.

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 Alpha Ridge is a major volcanic ridge under the Arctic Ocean between the Canada Basin and the Lomonosov Ridge. It was active during the formation of the Amerasian Basin. It was discovered in 1963. The highest elevation is about 2,700 m over the ocean floor. It is 200 to 450 km wide. The Alpha Ridge, Lomonosov Ridge, and Nansen-Gakkel Ridge are the three major ranges that divide the Arctic Ocean floor, running generally parallel to each other.
Mount Odin is a mountain in Qikiqtaaluk, Nunavut, Canada. It is located in Auyuittuq National Park along the Akshayuk Pass, 46 km (29 mi) north of Pangnirtung and south of Mount Asgard. Mount Odin is the highest mountain on Baffin Island.
The Princess Margaret Range, also called the Princess Margaret Mountains, are a mountain range on Axel Heiberg Island in Nunavut, Canada. The range is one of the most northern ranges in the world and of the Arctic Cordillera. The highest mountain in the range is Outlook Peak at 2,210 m (7,251 ft). The range has an area of 42,865 km2 (16,550 sq mi).
The Innuitian Region is a physiographic division of Canada's far north. It is one of three physiographic divisions of the Arctic Lands physiographic region, along with the Arctic Coastal Plain, and the Arctic Lowlands.The Queen Elizabeth Islands comprise most of the region, which is also considered to be part of the Arctic Archipelago.
The Joy Range is a mountain range of the Arctic Cordillera.
Dragon Cliff is a basaltic monolith located on western Axel Heiberg Island, Nunavut, Canada. It is the most striking feature of Expedition Fiord and rises several hundred metres out of the fiord. Dragon Cliff is made of flood basalt lava flows that contain more than 10 flow units totalling over 200 m (660 ft) of stratigraphic thickness. It is part of the Albian Strand Fiord Formation, which in turn forms part of the High Arctic Large Igneous Province. The Strand Fiord Formation is interpreted to represent the cratonward extension of the Alpha Ridge.
Eureka Pass is a mountain pass in the southern Princess Margaret Range of central Axel Heiberg Island, Nunavut, Canada.
Strand Fiord Pass is a mountain pass on southern Axel Heiberg Island, Nunavut, Canada.
Cape Thomas Hubbard is a headland located in the northern Canadian territory of Nunavut. Projecting into the Arctic Ocean, it is situated on the northern tip of Axel Heiberg Island, 320 mi (510 km) from Etah, Greenland.
The Sverdrup Channel is an area of sea in the Canadian Arctic Archipelago within the Qikiqtaaluk Region, Nunavut. To the north-west of the channel is Meighen Island, to the east is Axel Heiberg Island, and to the south is Amund Ringnes Island. The Fay Islands are located in the channel.
The Kanguk Formation is a geological formation in the Northwest Territories and Nunavut, Canada whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
Ulvingen Island is one of the uninhabited islands in Qikiqtaaluk Region, Nunavut, Canada. It is located in Norwegian Bay between Axel Heiberg Island and Ellesmere Island's Raanes Peninsula. It is a member of the Sverdrup Islands, Queen Elizabeth Islands, and the Arctic Archipelago. Hare Point is situated at the island's southern tip.
McGill Arctic Research Station (Expedition Fiord) (MARS) is a small research station operated by McGill University located near the centre of Axel Heiberg Island, Nunavut. It is located approximately 115 km (71 mi) southwest of Eureka, a weather and research station. It was first established in 1959 after scientists explored South Fiord (Expedition Fiord). The station contains a small hut, a cook house and two temporary structures. It can support 8-12 people and gives them access to the research activities. The current activities are glaciology, climate change, permafrost, hydrology, geology, geomorphology, limnology, planetary analogues, and microbiology. Today, the station is only used in the summer months so there would be enough power generated from the solar panels.
The Eurekan orogeny was a Phanerozoic mountain building event that affected the eastern portion of the Arctic Archipelago and, to a lesser extent, northern Greenland. Deformation initiated in the Late Cretaceous, during which time the Sverdrup Basin began to fragment and fold in response to the counterclockwise rotation of Greenland, caused by seafloor spreading in the Canadian Arctic Rift System. Isostatic uplift was most pronounced in the Grantland Mountains and Victoria and Albert Mountains on Ellesmere Island and in the Princess Margaret Range on Axel Heiberg Island, as evidenced by the current physiography. Compression in a broad zone on Ellesmere Island resulted in the formation of the Eurekan Fold Belt.
Pseudolarix wehrii is an extinct species of golden larch in the pine family (Pinaceae). The species is known from early Eocene fossils of northern Washington state, United States, and southern British Columbia, Canada, along with late Eocene mummified fossils found in the Qikiqtaaluk Region, Nunavut, Canada.
