  Glacier National Park (U.S. National Park Service)
Glacier National Park is experimenting with new ways to bring the park experience to visitors.
Glacier's award winning eHikes provide yet another means for virtual visitors to see, hear, and experience parts of the park they may never see in person, or to relive memorable experiences again and again.
Glacier is a natural laboratory and students and scientists use its resources to learn more about the world we live in.

  Glacier - Wikipedia, the free encyclopedia
Outlet glaciers are formed by the movement of ice from a polar ice cap, or an ice cap from mountainous regions, to the sea.
Glacial ice's distinctive blue tint, though often mistakenly attributed to Rayleigh scattering, is instead simply due to the fact that water itself is blue (owing to an overtone of an OH stretch which absorbs in the far red region of the visible spectrum).
Glacial erratics are rounded boulders that were left by a melting glacier and are often seen perched precariously on exposed rock faces after glacial retreat.

 glacier. The Columbia Encyclopedia, Sixth Edition. 2001-05
Piedmont glaciers, which occur only in high latitudes, are formed by the spreading of valley glaciers where they emerge from their valleys or by the confluence of several valley glaciers.
Glaciers are always in movement, but the extent of the apparent movement depends on the rate of advance and the rate of melting.
Important elements in glacial movement are melting under pressure followed by refreezing, which may push the mass in the direction of least resistance; sliding or shearing of layers of ice one on top of the other; and rearrangement of the granules when pressure causes melting.

 Ray Lloyd - Wikipedia, the free encyclopedia
Glacier had very memorable ring entrances in WCW, which included blue laser lights streaming across the arena, snow falling from the ceiling and dramatic theme music; according to Lloyd in a July 2000 interview, production costs for his entrance amounted to half a million dollars, while his costume cost $35,000.
On June 29, 1998, Glacier suffered a knee injury at the hands of Goldberg during a match on WCW Monday Nitro and was out for several months.
The irony of this was, of course, that Glacier had received a push one-and-a-half years earlier at these two men's expenses; now Kanyon and Wrath were being mildly pushed at his expense.

 Glacier - MSN Encarta
Glaciers form where the temperature is low enough to allow falling snow to accumulate and slowly transform into ice.
Glaciers are an intriguing part of Earth’s natural environment and their majestic beauty in wild and inaccessible mountain settings is unparalleled.
Glaciers occur in many different forms and locations, from the big ice sheet that covers the entire continent of Antarctica to the small valley glaciers that are present in many parts of the world.

 Glacier Glossary
On snowfields and glaciers, if the relative humidity (moisture content) of a packet of air is high enough that the air reaches the dew point as it cools in contact with the snow or ice, condensation occurs, releasing nearly 600 calories/gram of latent heat.
Proglacial lakes form the angle of the land and the angle of the glacier are opposite or in the superglacial/englacial environment.
In glaciers, if the relative humidity of a packet of air is high enough that the air reaches the dew point as it cools in contact with the snow or ice, condensation occurs, releasing +AH4- 680 calories/gram of latent heat.

 Glacier Retreat in the Pacific Northwest North Cascades National Park
This rapid glacier retreat is evident in the reduced stream flow and increased runoff in the area.
The increases in temperature is causing the retreat of the glaciers to increase at a rate that is effecting the streamflow and runoff in the area.
A glacier that illustrates the glacier retreat is the Lynch Glacier below which initially fills the lake basin in 1978, then retreats to the margin of the lake in 1985 and then retreats upslope from the lake by 1994.

 Dissecting a Glacier
The topmost portion of the Glacier, at its coldest portions, is known as the zone of accumulation.

 Glaciers and Icefields
Ice flows down the valleys and slopes of the mountains to the lower elevations, and glaciers are born.
As glaciers carve U-shaped valleys, rocks plucked from the bedrock and frozen in the ice etch grooves and striations in the bedrock.
Glacial recession unmasks trimlines, slightly sloping changes in vegetation or weathered bedrock on the valley walls that indicate a glacier's height at its glacial maximum.

 VIRTUAL TOUR OF TIERRA DEL FUEGO ~ WELCOME! ~ Charters, sailing adventures in Tierra Del Fuego and Cape Horn, Antarctic ...
While glaciers are of relatively minor importance today, evidence exists that the Earth's climate has undergone fluctuations in the past, and that the amount of the Earth's surface covered by glaciers has been much larger in the past than in the present.
A glacier is a permanent (on a human time scale, because nothing on the Earth is really permanent) body of ice, consisting largely of recrystallized snow, that shows evidence of downslope or outward movement due to the pull of gravity.

Although the glacier face shows little forward movement, the moraine appears to be thickening as more material is pushed into it by the glacier.
Glacier and land continue to form a narrow channel between Russell Fiord/Lake (background) and Disenchantment Bay (foreground).
The shaking from the advancing glacier settles the fine material to the bottom and brings the rocks (white specks in the picture) to the top of the pile.

The Columbia Glacier is now the single largest glacial contributor to sea level in North America, producing about 10 percent of the water volume entering the sea from all Alaskan glaciers each year, said Pfeffer.
The glacier's retreat appears to be due to a combination of complex physical processes, he said.

The shrinkage was apparent as we trekked down from the Eggishorn to Märjelensee, a glacial lake in a valley on the left bank of the glacier.
The glacier's fate determines all else in the valley.
As the glacier swelled, it mowed down trees and smothered alpine grazing ranges that had been in use for centuries; the valley below would be inundated by flash floods when the waters of the Märjelensee suddenly drained through a crevice.
