Holanda Glacier is a glacier located in Alberto de Agostini National Park, Chile. It is located at the east end of a group of glaciers line up on the north shore of the northwest arm of the Beagle Channel. The glacier terminus ends in a small proglacial lake.
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. 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.
Glacial motion is the motion of glaciers, which can be likened to rivers of ice. It has played an important role in sculpting many landscapes. Most lakes in the world occupy basins scoured out by glaciers. Glacial motion can be fast or slow, but is typically around 25 cm/day.
General Carrera Lake or "Lake Buenos Aires" is a lake located in Patagonia and shared by Argentina and Chile. Both names are internationally accepted.
The Biafo Glacier is a 67 km (42 mi) long glacier in the Karakoram Mountains of Gilgit Baltistan, Pakistan-administrated Kashmir which meets the 49 km (30 mi) long Hispar Glacier at an altitude of 5,128 m (16,824 ft) at Hispar La (Pass) to create the world's longest glacial system outside the polar regions. This highway of ice connects two ancient mountain kingdoms, Nagar, in the west with Baltistan in the east. The traverse uses 51 of the Biafo Glacier's 67 km and all of the Hispar Glacier to form a 100 km (62 mi) glacial route.
Hispar Glacier is a 49 km (30 mi) long glacier in the Karakoram Mountains of Gilgit–Baltistan, Pakistan which meets the 63 km (39 mi) long Biafo Glacier at the Hispar La (Pass) at an altitude of 5,128 m (16,824 ft) to create the world's longest glacial system outside of the polar regions.
Graham Bell Island is an island in the Franz Josef Archipelago in the Arctic Ocean, and is administratively part of Arkhangelsk Oblast, Russia.
Almirantazgo Fjord, also known as Almirantazgo Sound or Admiralty Sound, is a Chilean fjord located in the far south of the country at 54°19′S69°30′W. The fjord cuts deeply into the west coast of the Isla Grande de Tierra del Fuego, extending southeastwards from the Whiteside Channel, which separates Isla Grande from Dawson Island. On its south side several smaller fjords and bays make significant indentations into the north coastline of the Cordillera Darwin. One of these, Ainsworth Bay, is home to a colony of elephant seals. Azopardo River empties into the head of the fjord.
The Nordenskjöld is a lake in Torres del Paine National Park in the Magallanes Region, southern Chile. The lake is named after the Swede Otto Nordenskiöld who discovered the lake in the beginning of the 20th century. The outfall of Nordenskjöld Lake consists of a waterfall known as Salto Grande. At this western end of the lake on the southern side is an abundance of wildlife including wild grazing guanaco.
Grey Glacier is a glacier in the Southern Patagonian Ice Field, just west of the Cordillera del Paine. It flows southward into the lake of the same name. Before dividing in two at its front end, the glacier is 6 kilometers wide and over 30 meters high. In 1996, it occupied a total area of 270 km2 (100 sq mi) and a length of 28 km (17 mi). In November 2017 a large iceberg broke off the glacier.
El Yeso is a reservoir located in the Andes, in the Santiago Metropolitan Region, Chile. It was formed by the damming of the Yeso River, part of the Maipo river basin. The reservoir has a capacity of 250,000,000 m³ and was completed in 1964.
Magdalena Channel is a Chilean channel joining the Strait of Magellan with the Cockburn Channel and is part of a major navigation route which ultimately connects with the Beagle Channel. It separates Capitán Aracena Island from the westernmost portion of Isla Grande de Tierra del Fuego, and crosses Alberto de Agostini National Park. It is flanked by mountains, the chief of which is Monte Sarmiento. Like the Abra Channel and the Bárbara Channel farther west, it joins the western part of the Strait of Magellan directly to the Pacific Ocean.
Bertrand Lake is a Chilean lake located in the Aysén del General Carlos Ibáñez del Campo Region. It is separated from Plomo Lake by a terminal moraine and is flanked on the west by the summits of the Cordón Contreras.
Lobate debris aprons (LDAs) are geological features on Mars, first seen by the Viking Orbiters, consisting of piles of rock debris below cliffs. These features have a convex topography and a gentle slope from cliffs or escarpments, which suggest flow away from the steep source cliff. In addition, lobate debris aprons can show surface lineations as do rock glaciers on the Earth.
Romanche Glacier is a glacier located in Alberto de Agostini National Park, Chile. A cascade from the glacier tumbles into the Beagle Channel.
Italia Glacier is a tidewater glacier located in Alberto de Agostini National Park, Chile. It flows down in a southwest direction to its terminus in the Beagle Channel.
Alemania Glacier, also known as Roncagli Glacier, is a glacier located in Alberto de Agostini National Park, Chile. The advance of one of its lobes blocked the drainage of some streams, forming Martinic Lake.
Teniente Arturo Parodi Alister Base is a Chilean Antarctic research base located in the claimed Chilean Antarctic Territory. It was inaugurated on December 7, 1999, and was located about 1 km from the Patriot Hills Base Camp, operated by the American private company Adventure Network International, together with a blue ice aerodrome. After the transfer to the Union glacier of the operations of the company in November 2010, the base was disarmed and transferred to the Union glacier at the end of 2013. It operated from November to December every two years by the Air Force of Chile with a population of 25 people, but could provide life support to 40 people.
A glacier head is the top of a glacier. Although glaciers seem motionless to the observer they are in constant motion and the terminus is always either advancing or retreating.
