Kenai Fjords National Park
Kenai Fjords National Park is an American national park that maintains the Harding Icefield, its outflowing glaciers, and coastal fjords and islands. The park covers an area of on the Kenai Peninsula in south-central Alaska, west of the town of Seward, Alaska, Seward. The park contains the Harding Icefield, one of the largest ice fields in the United States, and is named for the numerous fjords carved by glaciers moving down the mountains from the ice field. The field is the source of at least 38 glaciers, the largest of which is Bear Glacier. The fjords are glacial valleys that have been submerged below sea level by a combination of sea level rise, rising sea levels and land subsidence. Exit Glacier is a popular destination at the end of the park's only road. The remainder of the park is accessible by boat, airplane, and hiking. Kenai Fjords National Monument was initially designated by President Jimmy Carter on December 1, 1978, using the Antiquities Act, pending final legi ...

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 ...

Aialik Bay
Aialik Bay, (Russian:) also known as Dora Passage between Harbor Island and the Harris Peninsula, is a fjord on the Kenai Peninsula of Alaska, United States. It has no permanent settlements, but there are two public use cabins located on the bay, one at its head and another at Holgate Arm. The Kenai Fjords lodge also hosts visitors. Aialik Bay is 33 miles south of Seward. The bay received its name from Russians recording the indigenous name as "Ayalyk Bay". It is likely that the bay once terminated at Aialik Sill, by Pedersen Lagoon prior to the year 1700. At this sill, the bay's bottom rises to less than 60 feet below sea level, and is as shallow as 18 feet deep in some places. Aialik Glacier, which has created the bay via the process of overdeepening, has since retreated by 4.5 miles. It is a major destination within the Kenai Fjords National Park, as many water taxis, kayak tours, anglers, and recreational boaters use the bay to access its many coves. Geography At its head ...

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.

Harding Icefield
The Harding Icefield is an expansive icefield located in the Kenai Mountains of the Kenai Peninsula in Alaska. It is also partially located in Kenai Fjords National Park. It is named for U.S. President Warren G. Harding. Geography The Harding Icefield is over 700 square miles (1813 km2) in its entirety (although, if one were to count its glaciers which descend from the icefield in all directions, the icefield measures in at over 1,100 square miles (2,849 km2) The icefield spawns up to 40 glaciers of all types. Some of the more notable glaciers include the Tustumena Glacier, Exit Glacier, and McCarty Glacier. The Exit Glacier, however, is the most accessible of the glaciers being reached by a spur road off of the Seward Highway. The icefield is also one of four remaining icefields in the United States and is the largest contained entirely within the United States. The icefield itself receives over 400 inches of snow each year. History Residents of Seward, A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seward, Alaska
Seward (Alutiiq: ; Dena'ina: ''Tl'ubugh'') is an incorporated home rule city in Alaska, United States. Located on Resurrection Bay, a fjord of the Gulf of Alaska on the Kenai Peninsula, Seward is situated on Alaska's southern coast, approximately by road from Alaska's largest city, Anchorage. With a population of 2,717 people as of the 2020 census, Seward is the fourth-largest city in the Kenai Peninsula Borough, behind Kenai, Homer, and the borough seat of Soldotna. The city is named for former U.S.A Secretary of State William H. Seward, who orchestrated the United States' purchase of Alaska from the Russian Empire in 1867 while serving in this position as part of President Andrew Johnson's administration. Seward is the southern terminus of the Alaska Railroad and the historic starting point of the original Iditarod Trail to Interior Alaska, with Mile 0 of the trail marked on the shoreline at the southern end of town.

Glacial Lake Outburst Flood
A glacial lake outburst flood (GLOF) is a type of outburst flood caused by the failure of a dam containing a glacial lake. An event similar to a GLOF, where a body of water contained by a glacier melts or overflows the glacier, is called a jökulhlaup. The dam can consist of glacier ice or a terminal moraine. Failure can happen due to erosion, a buildup of water pressure, an avalanche of rock or heavy snow, an earthquake or cryoseism, volcanic eruptions under the ice, or massive displacement of water in a glacial lake when a large portion of an adjacent glacier collapses into it. Increasing glacial melting because of climate change, alongside other environmental effects of climate change (i.e permafrost melting) mean that regions with glaciers are likely to see increased flooding risks from GLOFs. This is especially true in the Himalayas where geologies are more active. Definition A glacial lake outburst flood is a type of outburst flood occurring when water dammed by a glac ...

Ice Calving
Ice calving, also known as glacier calving or iceberg calving, is the breaking of ice chunks from the edge of a glacier.Essentials of Geology, 3rd edition, Stephen Marshak It is a form of ice ablation or ice disruption. It is the sudden release and breaking away of a mass of ice from a glacier, iceberg, ice front, ice shelf, or crevasse. The ice that breaks away can be classified as an iceberg, but may also be a growler, bergy bit, or a crevasse wall breakaway.Glossary of Glacier Terms Ellin Beltz, 2006. Retrieved July 2009. Calving of glaciers is often accompanied by a loud cracking or booming sound before blocks of ice up to high break loose and crash into the water. The entry of the ice into the water causes large, and often hazardous waves. The waves formed in locations like |
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, ...
