Glaciers in the context of "River"

The Accursed Mountains (Albanian: Bjeshkët e Nemuna; Serbo-Croatian: Prokletije / Проклетије, pronounced [prɔklɛ̌tijɛ]; both translated as "Cursed Mountains"), also known as the Albanian Alps (Albanian: Alpet Shqiptare; Serbo-Croatian: Albanski Alpi / Албански Алпи), is a mountain range in coastal Southeast Europe adjacent to the Adriatic Sea. It is the southernmost subrange of the 1,000-kilometre-long (621 mi) Dinaric Alps range (Dinarides), extending from northern Albania to western Kosovo and northeastern Montenegro. Maja Jezercë, standing at 2,694 m (8,839 ft), is the highest point of the Accursed Mountains and of all Dinaric Alps, and the fifth highest peak in Albania. The range includes the mountain Zla Kolata, which, at 2,534 m (8,314 ft), is the tallest mountain in Montenegro. The range also includes the mountain Gjeravica, which, at 2,656 m (8,714 ft), is the second tallest mountain in Kosovo. One of the southernmost glacial masses in Europe was discovered in the Albanian part of the range in 2009.

An ice field (also spelled icefield) is a mass of interconnected valley glaciers (also called mountain glaciers or alpine glaciers) on a mountain mass with protruding rock ridges or summits. They are often found in the colder climates and higher altitudes of the world where there is sufficient precipitation for them to form. The higher peaks of the underlying mountain rock that protrude through the icefields are known as nunataks. Ice fields are larger than alpine glaciers, but smaller than ice caps and ice sheets. The topography of ice fields is determined by the shape of the surrounding landforms, while ice caps have their own forms overriding underlying shapes.

Meltwater (or melt water) is water released by the melting of snow or ice, including glacial ice, tabular icebergs and ice shelves over oceans. Meltwater is often found during early spring when snow packs and frozen rivers melt with rising temperatures, and in the ablation zone of glaciers where the rate of snow cover is reducing. Meltwater can be produced during volcanic eruptions, in a similar way in which the more dangerous lahars form. It can also be produced by the heat generated by the flow itself.

When meltwater pools on the surface rather than flowing, it forms melt ponds. As the weather gets colder, meltwater will often re-freeze. Meltwater can also collect or melt under the ice's surface. These pools of water, known as subglacial lakes, can form due to geothermal heat and friction. Melt ponds may also form above and below Arctic sea ice, decreasing its albedo and causing the formation of thin underwater ice layers or false bottoms.

The Siachen Glacier is a glacier located in the eastern Karakoram range of the Himalayas, just northeast of the point NJ9842 where the Line of Control between India and Pakistan ends in northeastern Kashmir. At 76 km (47 mi) long, it is the longest glacier in the Karakoram and second-longest in the world's non-polar areas. It falls from an altitude of 5,753 m (18,875 ft) above sea level at its head at Indira Col on the India–China border down to 3,620 m (11,875 ft) at its terminus. The entire Siachen Glacier, with all major passes, has been under the administration of India as part of the union territory of Ladakh since 1984. Pakistan maintains a territorial claim over the Siachen Glacier and controls the region west of Saltoro Ridge, lying west of the glacier, with Pakistani posts located 1 km below more than 100 Indian posts on the ridge.

The Siachen Glacier lies immediately south of the great drainage divide that separates the Eurasian Plate from the Indian subcontinent in the extensively glaciated portion of the Karakoram sometimes called the "Third Pole". The glacier lies between the Saltoro Ridge immediately to the west and the main Karakoram range to the east. The Saltoro Ridge originates in the north from the Sia Kangri peak on the China border in the Karakoram range. The crest of the Saltoro Ridge's altitudes range from 5,450 to 7,720 m (17,880 to 25,330 feet). The major passes on this ridge are, from north to south, Sia La at 5,589 m (18,336 ft), Bilafond La at 5,450 m (17,880 ft), and Gyong La at 5,689 m (18,665 ft). The average winter snowfall is more than 1000 cm (35 ft) and temperatures can dip to −50 °C (−58 °F). Including all tributary glaciers, the Siachen Glacier system covers about 700 km (270 sq mi).

An ice shelf is a large platform of glacial ice floating on the ocean, fed by one or multiple tributary glaciers. Ice shelves form along coastlines where the ice thickness is insufficient to displace the more dense surrounding ocean water. The boundary between the ice shelf (floating) and grounded ice (resting on bedrock or sediment) is referred to as the grounding line; the boundary between the ice shelf and the open ocean (often covered by sea ice) is the ice front or calving front.

Ice shelves are found in Antarctica and the Arctic (Greenland, Northern Canada, and the Russian Arctic), and can range in thickness from about 100–1,000 m (330–3,280 ft). The world's largest ice shelves are the Ross Ice Shelf and the Filchner-Ronne Ice Shelf in Antarctica.
