|
They wound up paddling through an ice maze on a lake at the toe of a glacier. |
|
It took two days and a night, and involved the ascent of two mountains and an evening descent upon a rotten glacier. |
|
These sills mark areas at the coast where low relief makes it possible for a glacier to spread out and thus lose its erosional power. |
|
Near the toe of the glacier a party of three guys were loafing around their tent. |
|
In a clearing between clouds we could see just ahead an area of large seracs where the shifting glacier had cleaved into blocks. |

Effective techniques of fighting the enemy in the mountains are induced rockfalls, avalanches, glacier movements and mudslides. |
|
It provides an estimate of how much precipitation or temperature change must be invoked to explain the current net ablation of the glacier. |

|
While these lakes existed, they were maintained by the inflow of dirty meltwater from the receding glacier. |
|
There is enough filtered moonlight to reveal the tip of a glacier hanging like a tongue out of the mantle of clouds. |
|
Rain cascades down glacier carved valleys, gathering with the steady, icy melt to roam through the talus and house-sized boulders. |
|
We alternate for what seems like hours until we pass the seracs and the angle of the glacier is close to flat. |
|
In the center of the glacier I entered a maze of slot canyons made of pale blue ice. |
|
Our cuticles are already as barren of microbial life as the underside of an arctic glacier. |
|
A moraine is the ground up debris consisting of everything from giant boulders to fine rock powder which a glacier leaves behind. |
|
His body is trapped permanently in a glacier beneath the mountain that took him. |
|

|
Because the glacier moves a few inches a day, Gyalzen will build a temporary shelter with stone walls and use a tent for cover. |
|
There's a passage to the right, but it's under a huge serac that teeters at the end of a glacier, waiting for the next slight shift of ice to send it tumbling. |

Bridges and Greenwalt somehow convinced Geston to drive with them to glacier Park. |
|
They are accumulated at the base of the ice as lodgment till, but may also be deposited as the glacier retreats. |
|
End moraines, or terminal moraines, are ridges of unconsolidated debris deposited at the snout or end of the glacier. |
|
Glaciers act much like a conveyor belt, carrying debris from the top of the glacier to the bottom where it deposits it in end moraines. |
|
End moraine size and shape are determined by whether the glacier is advancing, receding or at equilibrium. |
|
The longer the terminus of the glacier stays in one place, the more debris accumulate in the moraine. |
|
Recessional moraines are small ridges left as a glacier pauses during its retreat. |
|
After a glacier retreats, the end moraine may be destroyed by postglacial erosion. |
|
They form perpendicular to the lateral moraines that they reside between and are composed of unconsolidated debris deposited by the glacier. |
|
It forms when two glaciers meet and the debris on the edges of the adjacent valley sides join and are carried on top of the enlarged glacier. |
|
As the glacier melts or retreats, the debris is deposited and a ridge down the middle of the valley floor is created. |
|
The bank originated as a terminal moraine of a glacier during one of the Ice Ages. |
|
|
The World Glacier Monitoring Service collects data annually on glacier retreat and glacier mass balance. |
|
In addition, the vast bodies of glacial ice affected Earth well beyond the glacier margins. |
|
The reason is that a continental glacier completely disrupts the preglacial drainage system. |
|
The surface over which the glacier moved was scoured and eroded by the ice, leaving a myriad of closed, undrained depressions in the bedrock. |
|
Winds near the glacial margins were strong and persistent because of the abundance of dense, cold air coming off the glacier fields. |
|
They are caused by earthquakes, landslides, volcanic explosions, glacier calvings, and bolides. |
|
A glacial lake outburst flood is a type of outburst flood occurring when water dammed by a glacier or a moraine is released. |
|
An iceberg or ice mountain is a large piece of freshwater ice that has broken off a glacier or an ice shelf and is floating freely in open water. |
|
This snow is then compacted to form glacier ice which moves under gravity towards the coast. |
|

|
During the Late Glacial glacier advance Dicksonland was situated on the peripheries of two local glaciation centers. |
|
Moraines, piles of rock picked up during the movement of the glacier, accumulate at edges, centre and the terminus of glaciers. |
|
Sometimes a piece of glacier will detach or break resulting in flooding, property damage and loss of life. |
|
|
The fourth side forms the lip, threshold or sill, the side at which the glacier flowed away from the cirque. |
|
They develop after the rock has been exposed by the scouring action of an ice sheet or glacier. |
|

|
Our streets are full of a general sloshiness that lingers and won't go away, as if a glacier is deicing to the north. |
|
During this last glacial period, there were several changes between glacier advance and retreat. |
|
They continued across the Grimsel Pass, through the upper Valais to Brig and on to the Aletsch glacier and Zermatt. |
|
This glacier was discovered in 2002 to be shrinking rapidly, and by 2007 had completely melted away, leaving the exposed island. |
|
Because of the gradient in pressure due to the overlying weight of the glacier, such streams can even flow uphill. |
|
These are ridges of stratified gravel and sand, running northwest to southeast, where the ancient edge of the glacier once lay. |
|
A large piece of compressed ice, or a glacier, appears blue, as large quantities of water appear blue. |
|
The process of glacier establishment, growth and flow is called glaciation. |
|
A glacier that fills a valley is called a valley glacier, or alternatively an alpine glacier or mountain glacier. |
|
|
Thermally, a temperate glacier is at melting point throughout the year, from its surface to its base. |
|
In a similar way, the thermal regime of a glacier is often described by its basal temperature. |
|
The blue of glacier ice is sometimes misattributed to Rayleigh scattering due to bubbles in the ice. |
|
A glacier originates at a location called its glacier head and terminates at its glacier foot, snout, or terminus. |
|
The upper part of a glacier, where accumulation exceeds ablation, is called the accumulation zone. |
|
The health of a glacier is usually assessed by determining the glacier mass balance or observing terminus behavior. |
|
In this process, a glacier slides over the terrain on which it sits, lubricated by the presence of liquid water. |
|
When a glacier moves through irregular terrain, cracks called crevasses develop in the fracture zone. |
|
If two rigid sections of a glacier move at different speeds and directions, shear forces cause them to break apart, opening a crevasse. |
|
Transverse crevasses are transverse to flow and form where steeper slopes cause a glacier to accelerate. |
|
Marginal crevasses form from the edge of the glacier, due to the reduction in speed caused by friction of the valley walls. |
|
Moving glacier ice can sometimes separate from stagnant ice above, forming a bergschrund. |
|
Meltwater can pool in proglacial lakes on top of a glacier or descend into the depths of a glacier via moulins. |
|
Friction makes the ice at the bottom of the glacier move more slowly than ice at the top. |
|
During these surges, the glacier may reach velocities far greater than normal speed. |
|
In glaciated areas where the glacier moves faster than one km per year, glacial earthquakes occur. |
|
Ogives are alternating wave crests and valleys that appear as dark and light bands of ice on glacier surfaces. |
|

|
If a retreating glacier gains enough debris, it may become a rock glacier, like the Timpanogos Glacier in Utah. |
|
They are formed by abrasion when boulders in the glacier are repeatedly caught and released as they are dragged along the bedrock. |
|
|
Material that becomes incorporated in a glacier is typically carried as far as the zone of ablation before being deposited. |
|
Glacial moraines are formed by the deposition of material from a glacier and are exposed after the glacier has retreated. |
|
As the water that rises from the ablation zone moves away from the glacier, it carries fine eroded sediments with it. |
|
Eskers are composed of sand and gravel that was deposited by meltwater streams that flowed through ice tunnels within or beneath a glacier. |
|
After the ice sheet or glacier melts, the mantle begins to flow back to its original position, pushing the crust back up. |
|
An ice dam is a blockage from the movement of a glacier which may produce a proglacial lake. |
|
As all of northern Europe experienced numerous Ice ages, glacier formation created ice flows and Ice sheets. |
|
The shallow Fender Valley, between these ridges, was carved out by a large glacier. |
|
These mountains also have the largest glacier on the mainland of Europe, Jostedalsbreen. |
|
Snow and glacier melt occur only in areas cold enough for these to form permanently. |
|
Typically snowmelt will peak in the spring and glacier melt in the summer, leading to pronounced flow maxima in rivers affected by them. |
|
Lateral moraines are formed at the side of the ice flow and terminal moraines at the foot, marking the maximum advance of the glacier. |
|
Moraines can be classified either by origin, location with respect to a glacier or former glacier, or by shape. |
|
Lateral moraines are parallel ridges of debris deposited along the sides of a glacier. |
|
Multiple lateral moraines may develop as the glacier advances and retreats. |
|

|
The glacier bear is found only in limited places in Southeast Alaska. |
|
His work was continued by other scientists and now a permanent laboratory exists inside a glacier under the Jungfraujoch, devoted exclusively to the study of Alpine glaciers. |
|
The line of equilibrium may shift drastically over short periods of time, leaving a whole glacier in the ablation area or in the accumulation area. |
|
In ice thrusting, the glacier freezes to its bed, then as it surges forward, it moves large sheets of frozen sediment at the base along with the glacier. |
|
Feedbacks are also possible between rates of erosion and the amount of eroded material that is already carried by, for example, a river or glacier. |
|
This first eruption, in the form of a fissure vent, did not occur under the glacier and was smaller in scale than had been expected by some geologists. |
|
Similarly, Arthur's Seat is the remains of a volcano dating from the Carboniferous period, which was eroded by a glacier moving west to east during the ice age. |
|
Instead the recent increases in glacier outflow are believed to be due to an inflow of warm water from the deep ocean, just off the continental shelf. |
|
Glaciotectonic structures and landforms were created throughout zones of former and modern glaciation as a result of glacier loading and movement on the crust. |
|
This displacement of water is usually attributed to either earthquakes, landslides, volcanic eruptions, glacier calvings or more rarely by meteorites and nuclear tests. |
|
A world glacier inventory has been compiled since the 1970s, initially based mainly on aerial photographs and maps but now relying more on satellites. |
|
Variability in temperature, precipitation, and englacial and subglacial hydrology can strongly determine the evolution of a glacier in a particular season. |
|
This debris can accumulate due to ice flow toward the surface in the ablation zone, melting of surface ice or from debris that falls onto the glacier from valley sidewalls. |
|
For a month last summer she crawled over and up the ice and rock of the mighty Ngozumpa glacier in Nepal, almost within spitting distance of Mount Everest. |
|
Lateral moraines stand high because they protect the ice under them from the elements, causing it to melt or sublime less than the uncovered parts of the glacier. |
|
The till is carried along the glacial margin until the glacier melts. |
|
In 2016, a glacier in the Antarctic was named the Glasser glacier, after Aberystwyth Geographer Professor Neil Glasser in recognition of his contribution to Polar Science. |
|
|
The glacier abrades the smooth slope on the upstream side as it flows along, but tears rock fragments loose and carries them away from the downstream side via plucking. |
|
The sea was dangerous because of icebergs calving off the nearby glacier. |
|
Less apparent are ground moraines, also called glacial drift, which often blankets the surface underneath the glacier downslope from the equilibrium line. |
|
Medial moraines are formed when two different glaciers merge and the lateral moraines of each coalesce to form a moraine in the middle of the combined glacier. |
|
Abrasion leads to steeper valley walls and mountain slopes in alpine settings, which can cause avalanches and rock slides, which add even more material to the glacier. |
|
Even at high latitudes, glacier formation is not inevitable. |
|
The permanent snow cover necessary for glacier formation is affected by factors such as the degree of slope on the land, amount of snowfall and the winds. |
|
A slight cooling led to the advance of many alpine glaciers between 1950 and 1985, but since 1985 glacier retreat and mass loss has become larger and increasingly ubiquitous. |
|
The ablation zone is the region where there is a net loss in glacier mass. |
|
This contrast is thought to a large extent to govern the ability of a glacier to effectively erode its bed, as sliding ice promotes plucking at rock from the surface below. |
|
The ice of a polar glacier is always below the freezing point from the surface to its base, although the surface snowpack may experience seasonal melting. |
|
During a glacial, the glacier experiences minor advances and retreats. |
|
That warm currents can lead to glacier formation may seem counterintuitive, but heated air flowing over the warm Gulf Stream can hold more moisture. |
|
The Sierra Nevada falls to Arctic temperatures in winter and has several dozen small glaciers, including Palisade Glacier, the southernmost glacier in the United States. |
|
When the fog lifted, the view of the glacier was a sight for sore eyes. |
|
Subglacial streams are the braided rivers that flow at the beds of glaciers and ice sheets, permitting meltwater to be discharged at the front of the glacier. |
|
The residential areas of Marchmont and Bruntsfield are built along a series of drumlin ridges south of the city centre, which were deposited as the glacier receded. |
