20091210 PNLG - Lago Viedma 137

Viedma Lake (Spanish: Lago Viedma), approximately 50 miles (80 kilometers) long in southern Patagonia near the border between Chile and Argentina. It's a major elongated trough lake formed from melting glacial ice.

The name of the lake comes from the Spanish explorer Antonio de Viedma, who in 1783 reached its shores, being the first European to do so.

The town of El Chaltén and the Andes peaks Cerro Torre and Fitz-Roy lie in the proximity of Lake Viedma.

Lake Viedma is fed primarily by the Viedma Glacier at its the western end. The Viedma Glacier measures 3 miles (5 kilometers) wide at its terminus at Lake Viedma. The brown landscape is a result of ice scouring, which left virtually no vegetation on the steep-walled valleys.

Water from lake Viedma flows into Lake Argentino through the La Leona River, and eventually from there into the Atlantic Ocean through the Santa Cruz River.

Although most of the lake lies in Argentine territory, the western shores of the lake reach the Southern Patagonian Ice Field in an area where the border remains undefined. Even if the Chilean territorial claims don't reach the shores, that could change as the glacial tongue in the lake melts.

Parque Nacional Los Glaciares (Spanish: The Glaciers) is a national park in the Santa Cruz Province, in Argentine Patagonia. It comprises an area of 4459 km². In 1981 it was declared a World Heritage Site by UNESCO.

The national park, created in 1937, is the second largest in Argentina. Its name refers to the giant ice cap in the Andes range that feeds 47 large glaciers, of which only 13 flow towards the Atlantic Ocean. The ice cap is the largest outside of Antarctica and Greenland. In other parts of the world, glaciers start at a height of at least 2,500 meters above mean sea level, but due to the size of the ice cap, these glaciers begin at only 1,500m, sliding down to 200m AMSL, eroding the surface of the mountains that support them.

Argentina ⁱ/ˌɑrdʒənˈtiːnə/, officially the Argentine Republic (Spanish: República Argentina [reˈpuβlika aɾxenˈtina]), is the second largest country in both South America and the Latin America region.

The country is a federation of 23 provinces and the autonomous city of Buenos Aires, its capital and largest city. It is the eighth-largest country in the world by land area and the largest among Spanish-speaking nations by geographical area of 2,780,400 km2 and is the fourth by population, with over 41 million people. Argentina is a founding member of the United Nations, Mercosur, the Union of South American Nations, the Organization of Ibero-American States, the World Bank Group and the World Trade Organization, and is one of the G-15 and G-20 major economies.

Patagonia is a region located at the southern end of South America, shared by Argentina and Chile. The region comprises the southern section of the Andes mountains to the southwest towards the Pacific ocean and from the east of the mountain range to the valleys it follows the Colorado River south towards Carmen de Patagones in the Atlantic Ocean. To the west, it includes the territory of Valdivia through Tierra del Fuego archipelago.

The name Patagonia comes from the word patagón used by Magellan in 1520 to describe the native people that his expedition thought to be giants. It is now believed the Patagons were actually Tehuelches with an average height of 180 cm (~5′11″) compared to the 155 cm (~5′1″) average for Europeans of the time.

The Argentine portion of Patagonia includes the provinces of Neuquén, Río Negro, Chubut and Santa Cruz, as well as the eastern portion of Tierra del Fuego archipelago and the southernmost department of Buenos Aires province: Patagones. The Argentine politico-economic Patagonic Region includes the Province of La Pampa.

South America, earlier known simply as America (1507–1538), is a continent located in the Western Hemisphere, mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere. It is also considered a subcontinent of the Americas.

It is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. It includes twelve sovereign states – Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela – and two non-sovereign areas – French Guiana, an overseas region of France, and the Falkland Islands, a British Overseas Territory. In addition to this, Trinidad and Tobago and the ABC islands of the Netherlands may also be considered part of South America.

This is a list of UNESCO World Heritage Sites in the Americas (North America, Central America, South America, and the Caribbean). Greenland has been included here as part of North America despite its cultural and political associations with Europe. Mexico leads the Americas hosting 31 sites, and is ranked the sixth in the world.

Estancia (American Spanish: [esˈtansja]) or Estância (Brazilian Portuguese: [iʃˈtɐ̃sjɐ]) is a Spanish and Brazilian Portuguese term describing a large rural estate with similarities to the English term ranch. The term is used in Argentina, Uruguay, southern Chile and southern Brazil. The equivalent in other Latin American countries would be hacienda, or fazenda (only in Brazil).

Unlike a hacienda, which could be any type of agricultural venture, producing grain, coffee, vegetable, beef, etc., an estancia, most typically located in the southern South American grasslands, the pampas, has historically always been a livestock (cattle or sheep) estate.

During the first centuries of Spanish colonial rule, cattle introduced by the Spanish roamed free and man undertook raids to catch and slaughter them.

In the 19th century stationary ranching ventures started to form in the pampas, with permanent buildings and marked livestock with clearly defined ownership. They were called estancias, the term indicating the stationary, permanent character.

The estancia's ranch worker on horseback, the gaucho, is of similar importance to national folklore and identity to the cowboy in North America.

Travel photography is a subcategory of photography involving the documentation of an area's landscape, people, cultures, customs and history. The Photographic Society of America defines a travel photo as an image that expresses the feeling of a time and place, portrays a land, its people, or a culture in its natural state, and has no geographical limitations.

Travel photography can either be created by professionals or amateurs. Examples of professional travel photography can be found in the National Geographic magazine. Amateur travel photography is often shared online through photo sharing websites like Flickr or niche travel photography websites such as TrekEarth.

Travel photography dates from the 1850s. Early practitioners include Francis Bedford, George Bridges, Maxime Du Camp, Solomon Nunes Carvalho, Francis Frith and James Ricalton.
