Alaska Range
The Alaska Range is a relatively narrow, 600-mile-long (950 km) mountain range in the southcentral region of the U.S. state of Alaska, from Lake Clark at its southwest endSources differ as to the exact delineation of the Alaska Range. ThBoard on Geographic Namesentry is inconsistent; part of it designates Iliamna Lake as the southwestern end, and part of the entry has the range ending at the Telaquana and Neacola Rivers. Other sources identify Lake Clark, in between those two, as the endpoint. This also means that the status of the Neacola Mountains is unclear: it is usually identified as the northernmost subrange of the Aleutian Range, but it could also be considered the southernmost part of the Alaska Range. to the White River in Canada's Yukon Territory in the southeast. The highest mountain in North America, Denali, is in the Alaska Range. It is part of the American Cordillera. The Alaska range is one of the higher ranges in the world after the Himalayas and the ...

Denali
Denali (; also known as Mount McKinley, its former official name) is the highest mountain peak in North America, with a summit elevation of above sea level. With a topographic prominence of and a topographic isolation of , Denali is the third most prominent and third most isolated peak on Earth, after Mount Everest and Aconcagua. Located in the Alaska Range in the interior of the U.S. state of Alaska, Denali is the centerpiece of Denali National Park and Preserve. The Koyukon people who inhabit the area around the mountain have referred to the peak as "Denali" for centuries. In 1896, a gold prospector named it "Mount McKinley" in support of then-presidential candidate William McKinley; that name was the official name recognized by the federal government of the United States from 1917 until 2015. In August 2015, 40 years after Alaska had done so, the United States Department of the Interior announced the change of the official name of the mountain to Denali. In 1903 ...

Aleutian Islands
The Aleutian Islands ( ; ; ale, Unangam Tanangin, "land of the Aleuts"; possibly from the Chukchi ''aliat'', or "island")—also called the Aleut Islands, Aleutic Islands, or, before 1867, the Catherine Archipelago—are a chain of 14 main, larger volcanic islands and 55 smaller ones. Most of the Aleutian Islands belong to the U.S. state of Alaska, with the archipelago encompassing the Aleutians West Census Area and the Aleutians East Borough. The Commander Islands, located further to the west, belong to the Russian federal subject of Kamchatka Krai, of the Russian Far East. The islands form part of the Aleutian Arc of the Northern Pacific Ocean, and occupy a land area of 6,821 sq mi (17,666 km2) that extends westward roughly from the Alaskan Peninsula mainland, in the direction of the Kamchatka Peninsula; the archipelago acts as a border between the Bering Sea to the north and the Pacific Ocean to the south.

Kahiltna Glacier
Kahiltna Glacier is the longest glacier of the Alaska Range in the U.S. state of Alaska. It starts on the southwest slope of Denali near Kahiltna Pass (elevation ). Its main channel runs almost due south between Mount Foraker to the west and Mount Hunter to the east. The name was first reported as "Car-ilt-nu Glacier" by Alaska Range explorer Lt. J.S. Herron in 1902. An alternate name is Kagheltnu Li'a. Kahiltna Glacier is the longest glacier in the Alaska Range at in length. Forks The glacier has a few notable forks. The Northeast Fork lies just under, and to the south of, the large plateau which houses the camp on the standard West Buttress route of Denali. It also provides access to the less popular, but more technical, West Rib and Cassin Ridge routes. The East Fork is rarely visited, but provides access to the west side of the South Buttress of Denali. The mouth of the Southeast Fork is the site of the seasonal airstrip and base camp for Denali at approximately the 7,0 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tokositna Glacier
Tokositna Glacier is a glacier in the Alaska Range of Denali National Park and Preserve in the U.S. state of Alaska. The glacier originates in two major arms on the east side of Mount Hunter, moving east until the main arms join, then turning south. Tokositna Glacier is the source of the Tokositna River. Spelling variants and alternate names include Tokasitna Glacier, Tokichitna Glacier and Tuqashitnu Li'a. Its thickness has been monitored by the National Park Service, which found consistent thinning since the 1990s.

Ruth Glacier
Ruth Glacier is a glacier in Denali National Park and Preserve in the U.S. state of Alaska. Its upper reaches are approximately 3 vertical miles below the summit of Denali. The glacier's "Great Gorge" is one mile wide, and drops almost 2,000 feet over 10 miles, with crevasses along the surface. Above the surface on both sides are 4,900-foot granite cliffs. From the top of the cliffs to the bottom of the glacier is a height exceeding that of the Grand Canyon. Ruth Glacier moves at a rate of three feet per day and was measured to be 4,000 feet thick in 1983. Surrounding the Ruth Gorge are many mountains of the Alaska Range, including the Mooses Tooth, Mount Dickey, Mount Bradley (Alaska), Mount Bradley, Mount Wake, Mount Johnson (Alaska), Mount Johnson, and London Tower (Alaska), London Tower with highly technical ice climbing, ice and climbing, rock climbs on their faces. History In 1903, the glacier was explored by physician and ethnographer Frederick Cook, who named it after his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eldridge Glacier
Eldridge Glacier is a major glacier in Denali National Park and Preserve in the U.S. state of Alaska. The long glacier originates on the east side of Explorers Peak, flowing northeast to a basin below Mount Eldridge, gathering flow from several glaciated cirques, then flowing southeast to the valley of the Chulitna River, where it gives rise to the Fountain River. A large unnamed tributary glacier joins Eldridge Glacier a few miles above its terminus.

Muldrow Glacier
Muldrow Glacier, also known as McKinley Glacier, is a large glacier in Denali National Park and Preserve in the U.S. state of Alaska. Native names for the glacier include, Henteel No' Loo' and Henteel No' Loot. The glacier originates from the Great Icefall of Harper Glacier on the eastern side of Denali. The glacier moves generally eastward, receiving Traleika Glacier and Brooks Glacier as tributaries, then turning northward to emerge from the Alaska Range as the source of the McKinley River. Muldrow Glacier was renamed by Alfred Hulse Brooks in 1902 in honor of U.S. Geological Survey topographer Robert Muldrow. In 2021, the glacier was noted to be growing in a surge that greatly exceeds the scant previous records of its status. In April that year scientists were documenting growth of the glacier at one hundred times its normal rate, advancing up to ninety feet a day during the prior few months.

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 over many years, often centuries. It acquires distinguishing features, such as crevasses and 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. Between latitudes 35°N and 35°S, glaciers occur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
