Logan Glacier (Alaska)
Logan Glacier is a glacier in the U.S. state of Alaska and territory of Yukon, Canada. It heads down the northern side of the Mount Logan massif in the Yukon, flowing northwest across the Canada-United States boundary to form the headwaters of the Chitina River. It was named for its origin on the slopes of, and proximity to, Mount Logan.

Alaska
Alaska ( ; russian: Аляска, Alyaska; ale, Alax̂sxax̂; ; ems, Alas'kaaq; Yup'ik: ''Alaskaq''; tli, Anáaski) is a state located in the Western United States on the northwest extremity of North America. A semi-exclave of the U.S., it borders the Canadian province of British Columbia and the Yukon territory to the east; it also shares a maritime border with the Russian Federation's Chukotka Autonomous Okrug to the west, just across the Bering Strait. To the north are the Chukchi and Beaufort Seas of the Arctic Ocean, while the Pacific Ocean lies to the south and southwest. Alaska is by far the largest U.S. state by area, comprising more total area than the next three largest states (Texas, California, and Montana) combined. It represents the seventh-largest subnational division in the world. It is the third-least populous and the most sparsely populated state, but by far the continent's most populous territory located mostly north of the 60th parallel, with ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Yukon
Yukon (; ; formerly called Yukon Territory and also referred to as the Yukon) is the smallest and westernmost of Canada's three territories. It also is the second-least populated province or territory in Canada, with a population of 43,964 as of March 2022. Whitehorse, the territorial capital, is the largest settlement in any of the three territories. Yukon was split from the North-West Territories in 1898 as the Yukon Territory. The federal government's ''Yukon Act'', which received royal assent on March 27, 2002, established Yukon as the territory's official name, though ''Yukon Territory'' is also still popular in usage and Canada Post continues to use the territory's internationally approved postal abbreviation of ''YT''. In 2021, territorial government policy was changed so that “''The'' Yukon” would be recommended for use in official territorial government materials. Though officially bilingual (English and French), the Yukon government also recognizes First Natio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Mount Logan
Mount Logan () is the highest mountain in Canada and the second-highest peak in North America after Denali. The mountain was named after Sir William Edmond Logan, a Canadian geologist and founder of the Geological Survey of Canada (GSC). Mount Logan is located within Kluane National Park Reserve in southwestern Yukon, less than north of the Yukon–Alaska border. Mount Logan is the source of the Hubbard and Logan glaciers. Although many shield volcanoes are much larger in size and mass, Mount Logan is believed to have the largest base circumference of any non-volcanic mountain on Earth, including a massif with eleven peaks over . Due to active tectonic uplifting, Mount Logan is still rising in height (approximately 0.35 mm per year). Before 1992, the exact elevation of Mount Logan was unknown and measurements ranged from . In May 1992, a GSC expedition climbed Mount Logan and fixed the current height of using GPS. Temperatures are extremely low on and near Mount Logan. On ...

Massif
In geology, a massif ( or ) is a section of a planet's crust that is demarcated by faults or flexures. In the movement of the crust, a massif tends to retain its internal structure while being displaced as a whole. The term also refers to a group of mountains formed by such a structure. In mountaineering and climbing literature, a massif is frequently used to denote the main mass of an individual mountain. The massif is a smaller structural unit of the crust than a tectonic plate, and is considered the fourth-largest driving force in geomorphology. The word is taken from French (in which the word also means "massive"), where it is used to refer a large mountain mass or compact group of connected mountains forming an independent portion of a range. One of the most notable European examples of a massif is the Massif Central of the Auvergne region of France. The Face on Mars is an example of an extraterrestrial massif. Massifs may also form underwater, as with the Atlanti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Glaciers
A glacier ( ) or () is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. Because glacial mass is affected by long-term climate changes, e.g., precipitation, mean temperature, and cloud cover, glacial mass changes are considered among the most sensitive indicators of climate change. There are about 198,000 to 200,000 glaciers in the world. Glaciers by continent Africa Africa, specifically East Africa, has contained glacial regions, possibly as far back as the last glacier maximum 10 to 15 thousand years ago. Seasonal snow does exist on the highest peaks of East Africa as well as in the Drakensberg Range of South Africa, the Stormberg Mountains, and the Atlas Mountains in Morocco. Currently, ...

Kluane National Park And Reserve
Kluane National Park and Reserve (; french: Parc national et réserve de parc national de Kluane) are two protected areas in the southwest corner of the territory of Yukon. The National Park Reserve was set aside in 1972 to become a national park, pending settlement of First Nations land claims. It covered an area of . When agreement was reached with the Champagne and Aishihik First Nations over an eastern portion of the Reserve, that part—about —became a national park in 1993, and is a unit of the national park system administered co-operatively with Parks Canada. The larger western section remains a Reserve, awaiting a final land claim settlement with the Kluane First Nation. The park borders B.C. to the south, while the Reserve borders both B.C. to the south, and the United States (Alaska) to the south and west. The Reserve includes the highest mountain in Canada, Mount Logan () of the Saint Elias Mountains. Mountains and glaciers, including Donjek Glacier, dominate t ...
