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, the only remaining glaciers on the continent exist on Mount Kilimanjaro, Mount Kenya, and the Rwenzori.

Antarctica

There are many glaciers in the Antarctic. This set of lists does not include ice sheets, ice caps or ice fields, such as the Antarctic ice sheet, but includes glacial features that are defined by their flow, rather than general bodies of ice. The lists include outlet glaciers, valley glaciers, cirque glaciers, tidewater glaciers and ice streams. Ice streams are a type of glacier and many of them have "glacier" in their name, e.g. Pine Island Glacier. Ice shelves are listed separately in the List of Antarctic ice shelves. For the purposes of these lists, the Antarctic is defined as any latitude further south than 60° (the continental limit according to the Antarctic Treaty System).

There are also glaciers in the subantarctic. This includes one snow field (Murray Snowfield). Snow fields are not glaciers in the strict sense of the word, but they are commonly found at the accumulation zone or head of a glacier. For the purposes of this list, Antarctica is defined as any latitude further south than 60° (the continental limit according to the Antarctic Treaty).

Europe

The majority of Europe's glaciers are found in the Alps, Caucasus and the Scandinavian Mountains (mostly Norway) as well as in Iceland. Iceland has the largest glacier in Europe, Vatnajökull glacier, that covers between 8,100-8,300 km² in area and 3,100 km³ in volume. Norway alone has more than 2500 glaciers (including very small ones) covering an estimated 1% of mainland Norway's surface area. Several of mainland Europe's biggest glaciers are found here including; Jostedalsbreen(the largest in mainland Europe at 487 km²), Vestre Svartisen (221 km²), Søndre Folgefonna (168 km²) and Østre Svartisen (148 km²). The two Svartisen glaciers used to be one connected entity during the Little Ice Age but has since separated.

North America

There are a number of glaciers existing in North America, currently or in recent centuries. In the United States, these glaciers are located in nine states, all in the Rocky Mountains or further west. The southernmost named glacier among them is the Lilliput Glacier in Tulare County, east of the Central Valley of California.

Mexico has about two dozen glaciers, all of which are located on Pico de Orizaba (Citlaltépetl), Popocatépetl and Iztaccíhuatl, the three tallest mountains in the country.

Oceania

No glaciers remain on the Australia mainland or Tasmania. A few, like the Heard Island glaciers are located in the territory of Heard Island and McDonald Islands in the southern Indian Ocean.

New Guinea has the Puncak Jaya glacier.

New Zealand contains many glaciers, mostly located near the Main Divide of the Southern Alps in the South Island. They are classed as mid-latitude mountain glaciers. There are eighteen small glaciers in the North Island on Mount Ruapehu.

An inventory of South Island glaciers compiled in the 1980s indicated there were about 3,155 glaciers with an area of at least one hectare (2.5 acres). Approximately one sixth of these glaciers covered more than 10 hectares. These include:
*Fox Glacier
*Franz Josef Glacier
* Hooker Glacier
*Mueller Glacier
* Murchison Glacier
*Tasman Glacier
*Volta Glacier

South America

Glaciers in South America develop exclusively on the Andes and are subject of the Andes various climatic regimes namely the Tropical Andes, Dry Andes and the Wet Andes. Apart from this there is a wide range of latitudes on which glaciers develop from 5000 m in the Altiplano mountains and volcanoes to reaching sealevel as tidewater glaciers from San Rafael Lagoon (45° S) and southwards. South America hosts two large ice fields, the Northern and Southern Patagonian Ice Fields, of which the latter is the second largest contiguous body of glaciers in extrapolar regions.

The glaciers of Venezuela are located in the mountains of the Sierra Nevada de Mérida. In 1910, maps made by the explorer Alfredo Jahn showed the Sierra Nevada glaciers covering about . An ice trade at that time saw ice men or hieleros transporting glacier ice by mule or on foot to Mérida for sale, a six hour journey.

Venezuela's glacier coverage shrank to about in 1952, and in 1985.

The last remaining glacier, located on Pico Humboldt, was estimated to cover in 2011.

List of longest glaciers on Earth in non-polar regions

The following is the list of longest glaciers in the non-polar regions, generally regarded as between 60 degrees north and 60 degrees south latitude, though some definitions expand it slightly.

# Fedchenko Glacier, Tajikistan – Exact lengths are relatively easy to determine with modern maps and imagery so as to include recent glacial retreat. Measurements are from recent imagery, supplemented with Russian 1:200,000 scale topographic mapping as well as the 1990 "Orographic Sketch Map: Karakoram: Sheet 2", Swiss Foundation for Alpine Research, Zurich.
# Siachen Glacier, Pakistan-India border, just northeast of the point NJ9842 where the Line of Control between India and Pakistan ends – using the longest route as is done when determining river lengths or if measuring from Indira Col
# Biafo Glacier, Pakistan –
# Brüggen Glacier, Chile –
# Baltoro Glacier, Pakistan –
# South Inylchek Glacier, Kyrgyzstan and China –
# Batura Glacier, Pakistan –
