A glacier (US /ˈɡleɪʃər/ or UK /ˈɡlæsiə/) 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. They also abrade rock and debris from their substrate to create landforms such as cirques and moraines. Glaciers form only on land and are 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 in the polar regions, but glaciers may be found in mountain ranges on every continent except Australia, and on a few high-latitude oceanic islands. Between 35°N and 35°S, glaciers occur only in the Himalayas, Andes, Rocky Mountains, a few high mountains in East Africa, Mexico, New Guinea and on Zard Kuh in Iran. Glaciers cover about 10 percent of Earth's land surface. Continental glaciers cover nearly 5 million square miles or about 98 percent of Antarctica's 5.1 million square miles, with an average thickness of 7,000 feet (2,100 m). Greenland and Patagonia also have huge expanses of continental glaciers.

Glacier National Park may refer to:
A national park is a park in use for conservation purposes. Often it is a reserve of natural, semi-natural, or developed land that a sovereign state declares or owns. Although individual nations designate their own national parks differently, there is a common idea: the conservation of 'wild nature' for posterity and as a symbol of national pride. An international organization, the International Union for Conservation of Nature (IUCN), and its World Commission on Protected Areas, has defined "National Park" as its Category II type of protected areas.
While this type of national park had been proposed previously, the United States established the first "public park or pleasuring-ground for the benefit and enjoyment of the people", Yellowstone National Park, in 1872. Although Yellowstone was not officially termed a "national park" in its establishing law, it was always termed such in practice and is widely held to be the first and oldest national park in the world. The first area to use "national park" in its creation legislation was the US's Mackinac Island, in 1875. Australia's Royal National Park, established in 1879, was the world's third official national park. In 1895 ownership of Mackinac Island was transferred to the State of Michigan as a state park and national park status was consequently lost. As a result, Australia's Royal National Park is by some considerations the second oldest national park now in existence.

Here are 14 amazing and beautiful ice formations around the world and you won't believe these extreme frozen things are actually real Subscribe to Talltanic http://goo.gl/wgfvrr 7. THE PASTERZE GLACIER, AUSTRIA Classified as one of Austria’s largest glaciers, the Pasterze Glacier is nestled at the bottom of the country’s largest mountain called the Grossglockner Mountain. The glacier is a relatively popular area for tourists to visit as it’s located near the equally popular lakeside resort called Zell am See. This is one of the easier glaciers to hike as the visitor’s center is near the Grossglocknerstrasse mountain road. This glacier won’t be around forever as each year it’s believed that the glacier recedes a staggering 33 feet each year so visit it if you get the chance to. 6. THE F...
This rare footage has gone on record as the largest glacier calving event ever captured on film, by the 2016 Guiness Book of World Records. On May 28, 2008, Adam LeWinter and Director Jeff Orlowski filmed a historic breakup at the Ilulissat Glacier in Western Greenland. The calving event lasted for 75 minutes and the glacier retreated a full mile across a calving face three miles wide. The height of the ice is about 3,000 feet, 300-400 feet above water and the rest below water. Footage produced by James Balog (http://jamesbalog.com) and the Extreme Ice Survey (http://extremeicesurvey.org) Chasing Ice won the award for Excellence in Cinematography at the 2012 Sundance Film Festival and a 2013 Emmy Award for Outstanding Nature Programming.

Glacier - Presently, 10 percent of land area on Earth is covered with glacial ice, including glaciers, ice caps, and the ice sheets of Greenland and Antarctica. Glacierized areas cover over 15 million square kilometers (5.8 million square miles). Glaciers store about 75 percent of the world's fresh water. During the maximum point of the last ice age, glaciers covered about 32 percent of the total land area.

Hi, I'm Emerald Robinson, and in this "What Is" video, we're going to investigate a very unique formation of ice called a glacier. A glacier is defined as a "slowly moving river of ice." But not all masses of ice are glaciers. To qualify to be a glacier, ice must be at least six hundredths of a square mile in size, and over one hundred and sixty four feet thick. Earth's largest glacier is Eastern Antarctica's Lambert Glacier, which is about sixty miles wide, over two hundred fifty miles long, and over eight thousand feet thick. Glaciers form in places where snow accumulates over a long period of time. As the snow gets deeper, the resulting weight and pressure turns the bottom layers of snow into ice. This high pressure, combined with the force of gravity, causes the glacier to move. ...
Glacier National Park is losing its iconic glaciers to a changing climate. In the mid-1800s, this Montana landscape was covered by 150 glaciers—today only 25 remain. To show the decrease in glacier size, scientists from the USGS Northern Rocky Mountain Science Center photograph the same areas where glaciers were photographed in the early 1900s. Dan Fagre, a USGS research ecologist, has been studying climate change in the park for more than 20 years. Fagre and his colleagues discuss what melting glaciers and climate change mean for the future of the park, which is expected to be nearly glacier free by 2030, based on present warming trends. ➡ Subscribe: http://bit.ly/NatGeoSubscribe About National Geographic: National Geographic is the world's premium destination for science, exploration, a...

Awaken the wolves
For my dreams have grown too quiet once again
Give me howling of footsteps
As time ambles drunk over tundra-glazed earth
Somewhere in the snow
Are the frozen tears and the teeth that battle broke
Twelve winters ago
When aging was living and murder was birth
Taste the cells dividing
All to come and all that's been
See the glaciers fighting
Melting over, pushing underneath your skin
Surrender your warmth
To find where ice crystals end and body starts
We walk the line
Between breath and wind and death and gravity
Awaken the martyr inside
And the ground that's solid, cold, and petrified
Before I open my eyes
Can you thaw this away and give my past to me?
Taste the cells dividing
All to come and all that's been
See the glaciers fighting
Melting over, pushing underneath your skin
Awaken the wolves
When the January moon needs lullabies
Awaken the wolves
When the sun's bright passion cannot reach the skies
Awaken the wolves
'Cause we're all alone here on the plains of frost
Awaken the wolves
And when we wake ourselves, shall winter's memory be lost?
Taste the cells dividing
All to come and all that's been
See the glaciers fighting
