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.

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] |
Outlet Glacier
Glacier morphology, or the form a glacier takes, is influenced by temperature, precipitation, topography, and other factors. The goal of glacial morphology is to gain a better understanding of glaciated landscapes and the way they are shaped. Types of glaciers can range from massive ice sheets, such as the Greenland ice sheet, to small cirque glaciers found perched on mountain tops. Glaciers can be grouped into two main categories: * Ice flow is constrained by the underlying bedrock topography * Ice flow is unrestricted by surrounding topography Unconstrained Glaciers Ice sheets and ice caps Ice sheets and ice caps cover the largest areas of land in comparison to other glaciers, and their ice is unconstrained by the underlying topography. They are the largest glacial ice formations and hold the vast majority of the world's fresh water. Ice sheets Ice sheets are the largest form of glacial formation. They are continent sized ice masses that span areas over . They are dome s ... [...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] |
Hans Steffen
250px, Picture of Dr. Hans Steffen in 1916 Hans Steffen Hoffman (20 July 1865, in Fürstenwerder, Prussia – 7 April 1936, in Davos, Switzerland) was a German geographer and explorer of the Aysén Region in western Patagonia. Steffen also worked as a teacher, encyclopedist and historian. Steffen Glacier on the Northern Patagonian Ice Field is named after him. Biography In 1889, Hans Steffen, who had obtained his doctorate in 1886, was invited by José Manuel Balmaceda to Santiago, where he became a teacher of history and geography at the Instituto Pedagógico de Chile of the University of Chile (together with the Germans Alfred Beutell, Friedrich Hanssen, Friedrich Johow, Rudolf Lenz, Reinhold von Lilienthal, and Jürgen Heinrich Schneider). He was later contracted to join the Chilean boundary commission to explore areas disputed by Argentina in what is now the Aysén Region of Chile. The areas to be explored were those affected by article 1 of the Boundary treaty of 1881 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Treaty Of Arbitration Between Chile And The Argentine Republic Of 1902
The 1902 Arbitral award of the Andes between Argentina and Chile ( es, Laudo limítrofe entre Argentina y Chile de 1902) was a British arbitration in 1902 that established the present-day boundaries between Argentina and Chile. In northern and central Patagonia, the borders were established between the latitudes of 40° and 52° S as an interpretation of the Boundary treaty of 1881 between Chile and Argentina. As result of the arbitration, some Patagonian lakes, such as O'Higgins/San Martín Lake, became divided by a national boundary. Additionally the preferences of settled colonists in a cultivated part of the area in dispute had been canvassed. The boundary proposed in the arbitration was a compromise between the boundary preferences of the two disputing governments, which strictly followed neither the alignment of highest peaks nor the fluvial watershed, and was published in the name of King Edward VII.

Katalalixar National Reserve
Katalalixar National Reserve is a natural reserve located in an archipelago between Southern Patagonian Ice Field, and Northern Patagonian Ice Field in Aysén del General Carlos Ibáñez del Campo Region of Chile. The reserve was created in 1983 and has no infrastructure. It covers an area of within the Magellanic subpolar forests ecoregion and exhibits more biodiversity than other areas of southern Chile. This may appear contradictory, as the area is supposed to have been covered by the Patagonian Ice Sheet upright=1.4, Map showing the extent of the Patagonian Ice Sheet in the Strait of Magellan area during the last glacial period.

Cerro Arenales
Cerro Arenales is a heavily ice-covered stratovolcano located in the Aysén del General Carlos Ibáñez del Campo Region of Chile, within Laguna San Rafael National Park. It towers over the southern part of the Northern Patagonian Ice Field. Arenales has a summit elevation of 3,437 meters (11276 feet) above sea level. Climbing The first ascent of Cerro Arenales was made in 1958 by a Japanese-Chilean expedition, headed by Professor Tanaka. In December 1963 an expedition led by Eric Shipton, crossed the NPIF heading southeast from Laguna San Rafael to Río de la Colonia and accomplished on the way the second ascent.

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, ...
