The Hunku Glacier is located in the Khumbu region of eastern Nepal and forms the southern base of Baruntse mountain (7,220 m). [1]
A glacier is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water.
A moraine is any accumulation of unconsolidated debris, sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines and medial moraines.
The Karakoram is a mountain range in the disputed Kashmir region spanning the borders of Pakistan, China, and India, with the northwestern extremity of the range extending to Afghanistan and Tajikistan. Most of the Karakoram mountain range falls under the jurisdiction of Gilgit-Baltistan, which is administered by Pakistan. Its highest peak, K2, is located in Gilgit-Baltistan. It begins in the Wakhan Corridor (Afghanistan) in the west, encompasses the majority of Gilgit-Baltistan, and extends into Ladakh and Aksai Chin.
Glacier National Park is an American national park located in northwestern Montana, on the Canada–United States border, adjacent to Waterton Lakes National Park in Canada—the two parks are known as the Waterton-Glacier International Peace Park. The park encompasses more than 1 million acres (4,000 km2) and includes parts of two mountain ranges, more than 130 named lakes, more than 1,000 different species of plants, and hundreds of species of animals. This vast pristine ecosystem is the centerpiece of what has been referred to as the "Crown of the Continent Ecosystem," a region of protected land encompassing 16,000 sq mi (41,000 km2).
Glaciology is the scientific study of glaciers, or, more generally, ice and natural phenomena that involve ice.
The Beardmore Glacier in Antarctica is one of the largest valley glaciers in the world, being 200 km (125 mi) long and having a width of 40 km (25 mi). It descends about 2,200 m (7,200 ft) from the Antarctic Plateau to the Ross Ice Shelf and is bordered by the Commonwealth Range of the Queen Maud Mountains on the eastern side and the Queen Alexandra Range of the Central Transantarctic Mountains on the western. Its mouth is east of the Lennox-King Glacier. It is northwest of the Ramsey Glacier.
Baruntse is a mountain in the Khumbu region of eastern Nepal, crowned by four peaks and bounded on the south by the Hunku Glacier, on the east by the Barun Glacier, and on the northwest by the Imja Glacier. The mountain was first climbed May 30, 1954 via the south ridge by Colin Todd and Geoff Harrow of a New Zealand expedition led by Sir Edmund Hillary. The first ascent of the East Ridge was made on April 27, 1980 by Lorenzo Ortas, Javier Escartín, Jeronimo Lopez and Carlos Buhler (America) of a Spanish expedition led by Juan José Díaz Ibañez.
Minnesota Glacier is a broad glacier, about 40 nautical miles long and 5 nautical miles wide, flowing east through the Ellsworth Mountains in Antarctica, separating the Sentinel Range and the Heritage Range. It is nourished by ice from the plateau west of the mountains and by Nimitz Glacier and Splettstoesser Glacier, and merges into the larger Rutford Ice Stream at the eastern margin of the Ellsworth Mountains.
Shackleton Glacier is a major Antarctic glacier, over 60 nautical miles long and from 5 to 10 nautical miles wide, descending from the Antarctic Plateau from the vicinity of Roberts Massif and flowing north through the Queen Maud Mountains to enter the Ross Ice Shelf between Mount Speed and Waldron Spurs. Discovered by the United States Antarctic Service (USAS) (1939–41) and named by the Advisory Committee on Antarctic Names (US-ACAN) for Sir Ernest Shackleton, British Antarctic explorer.
Lillie Glacier is a large glacier in Antarctica, about 100 nautical miles long and 10 nautical miles wide. It lies between the Bowers Mountains on the west and the Concord Mountains and Anare Mountains on the east, flowing to Ob' Bay on the coast and forming the Lillie Glacier Tongue.
Tucker Glacier is a major valley glacier of Victoria Land, Antarctica, about 90 nautical miles long, flowing southeast between the Admiralty Mountains and the Victory Mountains to the Ross Sea. There is a snow saddle at the glacier's head, just west of Homerun Range, from which the Ebbe Glacier flows northwestward.
The Siachen Glacier is a glacier located in the eastern Karakoram range in the Himalayas at about 35.421226°N 77.109540°E, just northeast of the point NJ9842 where the Line of Control between India and Pakistan ends. 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, located in the Kashmir region 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 retreat of glaciers since 1850 is well documented and is one of the effects of climate change. The retreat of mountain glaciers, notably in western North America, Asia, the Alps and tropical and subtropical regions of South America, Africa and Indonesia, provide evidence for the rise in global temperatures since the late 19th century. The acceleration of the rate of retreat since 1995 of key outlet glaciers of the Greenland and West Antarctic ice sheets may foreshadow a rise in sea level, which would affect coastal regions. Excluding peripheral glaciers of ice sheets, the total cumulated global glacial losses over the 26-year period from 1993 to 2018 were likely 5500 gigatons, or 210 gigatons per yr.
A glacier terminus, toe, or snout, is the end of a glacier at any given point in time. Although glaciers seem motionless to the observer, in reality they are in endless motion and the glacier terminus is always either advancing or retreating. The location of the terminus is often directly related to glacier mass balance, which is based on the amount of snowfall which occurs in the accumulation zone of a glacier, as compared to the amount that is melted in the ablation zone. The position of a glacier terminus is also impacted by localized or regional temperature change over time.
The Mariner Glacier is a major glacier over 60 nautical miles long, descending southeast from the plateau of Victoria Land, Antarctica, between Mountaineer Range and Malta Plateau, and terminating at Lady Newnes Bay, Ross Sea, where it forms the floating Mariner Glacier Tongue.
