Paradise Ice Caves
The Paradise Ice Caves (also known as the Paradise Glacier Caves) were a system of interconnected glacier caves located within Mount Rainier's Paradise Glacier in the United States The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territorie .... These glacier caves were visited and documented at least as early as 1908. They have a varied natural history, as their size and even existence has changed over time, from a maximum surveyed length of 13.25 kilometers in 1978, to not existing at all during both the 1940s and 1990s due to glacial recession. In 1978 they were the longest mapped system of glacier caves in the world. References External links Paradise Ice Caves and Camp MuirParadise Ice Caves Tour, Mt.

Paradise Ice Glacier Cave
In religion, paradise is a place of exceptional happiness and delight. Paradisiacal notions are often laden with pastoral imagery, and may be cosmogonical or eschatological or both, often compared to the miseries of human civilization: in paradise there is only peace, prosperity, and happiness. Paradise is a place of contentment, a land of luxury and fulfillment. Paradise is often described as a "higher place", the holiest place, in contrast to this world, or underworlds such as Hell. In eschatological contexts, paradise is imagined as an abode of the virtuous dead. In Christianity and Islam, Heaven is a paradisiacal relief. In old Egyptian beliefs, the underworld is Aaru, the reed-fields of ideal hunting and fishing grounds where the dead lived after judgment. For the Celts, it was the Fortunate Isle of Mag Mell. For the classical Greeks, the Elysian fields was a paradisiacal land of plenty where the heroic and righteous dead hoped to spend eternity. In Buddhism, paradise and ...

Glacier Cave
A glacier cave is a cave formed within the ice of a glacier. Glacier caves are often called ice caves, but the latter term is properly used to describe bedrock caves that contain year-round ice. Overview Most glacier caves are started by water running through or under the glacier. This water often originates on the glacier's surface through melting, entering the ice at a moulin and exiting at the glacier's snout at base level. Heat transfer from the water can cause sufficient melting to create an air-filled cavity, sometimes aided by solifluction. Air movement can then assist enlargement through melting in summer and sublimation in winter. Some glacier caves are formed by geothermal heat from volcanic vents or hotsprings beneath the ice. An extreme example is the Kverkfjöll glacier cave in the Vatnajökull glacier in Iceland, measured in the 1980s at long with a vertical range of . Some glacier caves are relatively unstable due to melting and glacial motion, and are sub ... [...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.

Paradise Glacier
Paradise Glacier is a glacier on the southeast flank of Mount Rainier in Washington. It covers and contains 0.8 billion ft3 (23 million m3) with Stevens Glacier included. The glacier is bounded to the west by the Muir Snowfield, Anvil Rock and McClure Rock. There is a single extant main lobe of the glacier, ranging from to , that is connected to the larger Cowlitz Glacier. To the south, there was a smaller portion which was near the Cowlitz Rocks and the tiny Williwakas Glacier, ranging from to in elevation and containing the Paradise Ice Caves until the 1990s. This smaller lobe melted between 2004 and 2006. Meltwater from the glacier drains into the Cowlitz River. Glacier loss The Williwakas was declared a dead glacier in the 1930s and the ice caves were lost in the 1980s. In a June 2023 report from the National Park Service (NPS), the Stevens Glacier was removed from the NPS glacier list for lack of ice flow and size.

Glacial Recession
Glacial motion is the motion of glaciers, which can be likened to rivers of ice. It has played an important role in sculpting many landscapes. Most lakes in the world occupy basins scoured out by glaciers. Glacial motion can be fast (up to , observed on Jakobshavn Isbræ Jakobshavn Glacier ( da, Jakobshavn Isbræ), also known as Ilulissat Glacier ( kl, Sermeq Kujalleq), is a large outlet glacier in West Greenland. It is located near the Greenlandic town of Ilulissat (colonial name in da, Jakobshavn) and ends a ... in Greenland) or slow ( on small glaciers or in the center of ice sheets), but is typically around . Processes of motion Glacier motion occurs from four processes, all driven by gravity: basal sliding, glacial quakes generating fractional movements of large sections of ice, bed deformation (science), deformation, and internal deformation. * In the case of basal sliding, the entire glacier slides over its bed. This type of motion is enhanced if the bed is soft sed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caves Of Washington (state)
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganisms ...

Glaciology Of The United States
Glaciology (; ) is the scientific study of glaciers, or more generally ice and natural phenomena that involve ice. Glaciology is an interdisciplinary Earth science that integrates geophysics, geology, physical geography, geomorphology, climatology, meteorology, hydrology, biology, and ecology. The impact of glaciers on people includes the fields of human geography and anthropology. The discoveries of water ice on the Moon, Mars, Europa and Pluto add an extraterrestrial component to the field, which is referred to as "astroglaciology". Overview A glacier is an extended mass of ice formed from snow falling and accumulating over a long period of time; glaciers move very slowly, either descending from high mountains, as in valley glaciers, or moving outward from centers of accumulation, as in continental glaciers. Areas of study within glaciology include glacial history and the reconstruction of past glaciation. A glaciologist is a person who studies glaciers. A glacial geologist ...

Mount Rainier National Park
Mount Rainier National Park is an American national park located in southeast Pierce County and northeast Lewis County in Washington state. The park was established on March 2, 1899, as the fourth national park in the United States, preserving including all of Mount Rainier, a stratovolcano. The mountain rises abruptly from the surrounding land with elevations in the park ranging from 1,600 feet to over 14,000 feet (490–4,300 m). The highest point in the Cascade Range, Mount Rainier is surrounded by valleys, waterfalls, subalpine meadows, and of old-growth forest. More than 25 glaciers descend the flanks of the volcano, which is often shrouded in clouds that dump enormous amounts of rain and snow. Mount Rainier is circled by the Wonderland Trail and is covered by glaciers and snowfields totaling about . Carbon Glacier is the largest glacier by volume in the contiguous United States, while Emmons Glacier is the largest glacier by area. Mount Rainier is a popula ...
