Nef Glacier
Nef Glacier is a glacier located in Laguna San Rafael National Park, in the Aysén del General Carlos Ibáñez del Campo Region of Chile. It trends southeast from Cerro Largo to its terminus in the lake that shared its name. It is the fifth largest glacier in the Northern Patagonian Ice Field The Northern Patagonian Ice Field, located in southern Chile, is the smaller of two remnant parts in which the Patagonian Ice Sheet in the Andes Mountains of southern South America can be divided.

Chile
Chile, officially the Republic of Chile, is a country in the western part of South America. It is the southernmost country in the world, and the closest to Antarctica, occupying a long and narrow strip of land between the Andes to the east and the Pacific Ocean to the west. Chile covers an area of , with a population of 17.5 million as of 2017. It shares land borders with Peru to the north, Bolivia to the north-east, Argentina to the east, and the Drake Passage in the far south. Chile also controls the Pacific islands of Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island in Oceania. It also claims about of Antarctica under the Chilean Antarctic Territory. The country's capital and largest city is Santiago, and its national language is Spanish. Spain conquered and colonized the region in the mid-16th century, replacing Inca rule, but failing to conquer the independent Mapuche who inhabited what is now south-central Chile. In 1818, after declaring in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacier
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#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, 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. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Laguna San Rafael National Park
Laguna San Rafael National Park () is a park located on the Pacific coast of southern Chile. The park is named for the San Rafael Lagoon formed by the retreat of the San Rafael Glacier. Created in 1959, it covers an area of and includes the Northern Patagonian Ice Field. A fjord more than long is one of the park's principal attractions. History Non-indigenous people first explored the area of Laguna San Rafael in the year 1675. The glacier of the same name was a land-terminating glacier during that time. It probably reached again the lagoon at some time between 1741 and 1766, and it has been a tidewater glacier since that date. The park was designated a World Biosphere Reserve by UNESCO in 1979.UNESCO - Park description at UNESCO World Biosphere Reserve Geography The park comprises some of ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Patagonian Ice Field
The Northern Patagonian Ice Field, located in southern Chile, is the smaller of two remnant parts in which the Patagonian Ice Sheet in the Andes Mountains of southern South America can be divided. It is completely contained within the boundaries of Laguna San Rafael National Park. Description The Northern Patagonian Ice Field is a vestige of the Patagonian Ice Sheet, an extensive ice sheet that covered all of Chilean Patagonia and the westernmost parts of Argentine Patagonia during the Quaternary glaciations. Today, with its glaciers largely in retreat and only an area of , it is still the second largest continuous mass of ice outside of the polar regions. Its survival depends on its elevation (), favorable terrain and a cool, moist, oceanic climate. The ice field has 28 exit glaciers, the largest two — San Quintin and San Rafael — nearly reach sea level to the west at the Pacific Ocean. Smaller exit glaciers, like San Valentín and Nef, feed numerous rivers and glacially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Quintín Glacier
The San Quintín Glacier is the largest outflow glacier of the Northern Patagonian Ice Field in southern Chile. Its terminus is a piedmont lobe just short of the Gulf of Penas on the Pacific Ocean and just north of 47°S. Recent retreat Like many glaciers worldwide during the twentieth century, San Quintín appears to be losing mass and retreating rapidly. These two photographs taken by astronauts only seven years apart show visible change. The first was taken by the crew of STS-068 in October 1994 and the second by the Increment 4 crew of the International Space Station in February 2002.

Steffen Glacier
Steffen Glacier is a major outlet glacier of the Northern Patagonian Ice Field in Aysén del General Carlos Ibáñez del Campo Region of Chile. It is the southernmost outlet glacier of the Northern Patagonian Ice Field and ends up in a lagoon from where Huemules River is born. The glacier is named after Hans Steffen a German geographer who explored Aysén del General Carlos Ibáñez del Campo Region on behalf of the Chilean government before the General Treaty of Arbitration between Chile and the Argentine Republic of 1902.

Colonia Glacier
Colonia Glacier (Spanish: ''Glaciar Colonia'' or ''Ventisquero Colonia'') is a valley glacier located in the Northern Patagonian Ice Field, Chile. The glacier spills out to the southeast from an ice plateau north of Cerro Arenales and has its terminus about from Colonia Lake. ''Colonia Glacier'' dams two lakes; Cachet II and Arco Lake. The ice dam containing the waters of Cachet II Lake fails regularly, which generates glacial lake outburst flood A glacial lake outburst flood (GLOF) is a type of outburst flood caused by the failure of a dam containing a glacial lake. An event similar to a GLOF, where a body of water contained by a glacier melts or overflows the glacier, is called a jö ...s. On March 31, 2012, for the second time that year, virtually all of the 200 million cubic meters of water in Lake Cachet II were lost in less than 24 hours as a result of perforations in the glacial wall, a consequence of rising temperatures driven by climate change.

Glaciers Of Chile
The glaciers of Chile cover 2.7% (20,188 km2) of the land area of the country, excluding Antártica Chilena, and have a considerable impact on its landscape and water supply. By surface 80% of South America's glaciers lie in Chile. Glaciers develop in the Andes of Chile from 27˚S southwards and in a very few places north of 18°30'S in the extreme north of the country: in between they are absent because of extreme aridity, though s formed from |
