South Mowich Glacier
The South Mowich Glacier is a glacier located on the western flank of Mount Rainier in Washington. It covers and contains 4.5 billion ft3 (127 million m3) of ice. Starting from the high-altitude cliffs above the Sunset Amphitheater at over , the glacier flows west down Mount Rainier. The glacier is connected to the large Tahoma Glacier to the south near St. Andrews Rock at . After leaving the Amphitheater, there is an icefall on the glacier where it plunges down below . As the glacier descends, it gradually turns and by the time the South Mowich meets the Puyallup Glacier at , the glacier is flowing northwest. As the glacier nears Jeanette Heights, it passes by several turns and becomes very rocky in comparison to the upper sections of the glacier. The glacier splits into two arms before their termini, with a shorter, northern arm ending at and the longer, larger southern arm ending near a stand of conifers at . Meltwater from the glacier drains into the South Mowich River which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Rainier
Mount Rainier (), indigenously known as Tahoma, Tacoma, Tacobet, or təqʷubəʔ, is a large active stratovolcano in the Cascade Range of the Pacific Northwest, located in Mount Rainier National Park about south-southeast of Seattle. With a summit elevation of , it is the highest mountain in the U.S. state of Washington and the Cascade Range, the most topographically prominent mountain in the contiguous United States, and the tallest in the Cascade Volcanic Arc. Due to its high probability of eruption in the near future, Mount Rainier is considered one of the most dangerous volcanoes in the world, and it is on the Decade Volcano list. The large amount of glacial ice means that Mount Rainier could produce massive lahars that could threaten the entire Puyallup River valley. According to the United States Geological Survey, "about 80,000 people and their homes are at risk in Mount Rainier's lahar-hazard zones." Between 1950 and 2018, 439,460 people climbed Mount Rainier.

Pierce County, Washington
Pierce County is a county in the U.S. state of Washington. As of the 2020 census, the population was 921,130, up from 795,225 in 2010, making it the second-most populous county in Washington, behind King County, and the 60th-most populous in the United States. The county seat and largest city is Tacoma. Formed out of Thurston County on December 22, 1852, by the legislature of Oregon Territory, it was named for U.S. President Franklin Pierce. Pierce County is in the Seattle metropolitan area (formally the Seattle-Tacoma-Bellevue, WA, metropolitan statistical area). Pierce County is home to Mount Rainier, the tallest mountain and a volcano in the Cascade Range. Its most recent recorded eruption was between 1820 and 1854. There is no imminent risk of eruption, but geologists expect that the volcano will erupt again. If this should happen, parts of Pierce County and the Puyallup Valley would be at risk from lahars, lava, or pyroclastic flows. The Mount Rainier Volcano Lahar ...

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.

State Of Washington
Washington (), officially the State of Washington, is a state in the Pacific Northwest region of the Western United States. Named for George Washington—the first U.S. president—the state was formed from the western part of the Washington Territory, which was ceded by the British Empire in 1846, by the Oregon Treaty in the settlement of the Oregon boundary dispute. The state is bordered on the west by the Pacific Ocean, Oregon to the south, Idaho to the east, and the Canadian province of British Columbia to the north. It was admitted to the Union as the 42nd state in 1889. Olympia is the state capital; the state's largest city is Seattle. Washington is often referred to as Washington state to distinguish it from the nation's capital, Washington, D.C. Washington is the 18th-largest state, with an area of , and the 13th-most populous state, with more than 7.7 million people. The majority of Washington's residents live in the Seattle metropolitan area, the center of transpo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tahoma Glacier
The Tahoma Glacier is a long glacier mostly on the western flank of Mount Rainier in Washington. It covers and contains of ice. The glacier starts out near the summit of the volcano at over . As the glacier flows west-southwest out of the summit area, it cascades down a steep rocky face as an icefall from to , where the glacier is connected to the South Mowich Glacier to the north in the Sunset Amphitheater. As the glacier drops below , it broadens and joins the smaller South Tahoma Glacier. After the broad expanse of ice at over , the Tahoma Glacier narrows as it descends around the rocky Glacier Island, a sub-peak of Rainier once fully encircled by both the South Tahoma and Tahoma Glaciers. Leaving the bottleneck in the glacier, the glacier splits; the larger, longer northern arm continues flowing west-southwest and terminates at around . The southern arm flows south towards the arm of the South Tahoma Glacier, but this arm terminates before it rejoins the South Tahoma at ...

Icefall
An icefall is a portion of certain glaciers characterized by relatively rapid flow and chaotic crevassed surface, caused in part by gravity. The term ''icefall'' is formed by analogy with the word ''waterfall'', which is a similar phenomenon of the liquid phase but at a more spectacular speed. When ice movement of a glacier is faster than elsewhere, because the glacier bed steepens or narrows, and the flow cannot be accommodated by plastic deformation, the ice fractures, forming crevasses. Where two fractures meet, seracs (or ice towers) can be formed. When the movement of the ice slows down, the crevasses can coalesce, resulting in the surface of the glacier becoming smoother. Ice flow Perhaps the most conspicuous consequence of glacier flow, icefalls occur where the glacier bed steepens and/or narrows. Most glacier ice flows at speeds of a few hundred metres per year or less. However, the flow of ice in an icefall may be measured in kilometres per year. Such rapid flow cannot ...

Puyallup Glacier
The Puyallup Glacier is a glacier on the west flank of Mount Rainier in Washington. It covers and contains 10.2 billion ft3 (289 million m3) of ice. Sharing the same source of ice as the northern South Mowich Glacier, the Puyallup Glacier begins as a branch off the ice stream that flow out of the Sunset Amphitheater. From the split at around , the glacier expands into a broad sheet of ice ranging from to in elevation. Leaving the large expanse of ice, the glacier flows down a small valley, it narrows significantly as it turns northwestward. From there on, the glacier is dirty and ends on steep, uneven terrain at about . The glacier gives rise to the Puyallup River.

Mowich River
The Mowich River is a river in the U.S. state of Washington (state), Washington. Its drainage basin, watershed drains a portion of the western side of Mount Rainier, part of the Cascade Range. The river has two main Source (river or stream), headwater branches, the South Mowich River and the North Mowich River. The South Mowich is significantly larger and sometimes considered the main river. The Mowich and its tributaries drain several of Mount Rainier's glaciers. The upper portion of its watershed is contained within Mount Rainier National Park. The river flows into the Puyallup River in the foothills west of Mount Rainier. The name "Mowich" come from the Chinook Jargon word for "deer". Originally used for Mowich Lake, the name was later applied to the river and the glacier. Sources Meltwater from Mount Rainier's Edmunds Glacier, South Mowich Glacier, and North Mowich Glacier feed the north and south branches of the Mowich River. Other rivers originate in glaciers just south and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puyallup River
The Puyallup River ( ) is a river in the U.S. state of Washington (state), Washington. About long, it is formed by glaciers on the west side of Mount Rainier. It flows generally northwest, emptying into Commencement Bay, part of Puget Sound. The river and its tributaries drain an area of about in Pierce County, Washington, Pierce County and southern King County, Washington, King County. The river's drainage basin, watershed is the youngest in the Puget Sound region, having been formed from a series of lahars starting about 5,600 years ago. The valley's 150,000 residents are at risk from future lahars. For this reason, the United States Geological Survey has installed a lahar warning system. Course The Puyallup River begins in two forks, the North Puyallup River and the South Puyallup River. Both originate at glaciers on Mount Rainier. The North Puyallup River flows from the toe of Puyallup Glacier, while the South Puyallup River flows from Tahoma Glacier. The two streams flow t ...

North Mowich Glacier
The North Mowich Glacier is a glacier located on the northwest flank of Mount Rainier in Washington. It covers and contains 9.5 billion ft3 (269 million m3) of ice. Starting from the foot of Rainier's steep Mowich Face at about , the glacier first consists of two lobes of ice that flow downhill to the northwest. The southern arm of the glacier is connected to the adjacent Edmunds Glacier. As the two sections of ice join up, they form a large, relatively flat plateau of ice ranging from to . This plateau is an unbroken expanse of ice except for Needle Rock, which pokes out of the glacier ice. From then on, the southern part of the glacier terminates at about , while the northern, rocky arm flows down a glacial valley and ends at about in elevation. The North Mowich Glacier gives rise to the North Mowich River.

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, ...
