Argentina – September 24th, 2012

Sediments line the coast of the Argentine provinces of Santa Cruz and Tierra del Fuego, both part of Patagonia, from the San Jorge Gulf to the Mitre Peninsula.

Visible parallel to the west coast are the Andes Mountains, along the border with Chile. Visible by the mountains are several bright blue glacial lakes (from north to south): Lake O’Higgins/San Martín (the former name is used in Chile, the latter in Argentina), Viedma Lake and Argentino Lake.

This image stretches across the Argentine province of Santa Cruz to Tierra del Fuego, shared by Chile and Argentina. Visible in the lower right corner is Mitre Peninsula, the easternmost part of Isla Grande de Tierra del Fuego.

The land to the east is snow-free, while that to the west, by the Andes Mountains, is snow-covered. Visible amidst the snow are three bright blue lakes: Lake O’Higgins/San Martín, Lake Viedma and Lake Argentino (from north to south).

The lake known as O’Higgins in Chile and San Martín in Argentina, is located in Patagonia, between the Aysén Region and the Santa Cruz Province. Its surface is of 1,058 km² at 250 metres above mean sea level, and has a shoreline length of 525 km. Viewed from above, the lake consists of a series of finger-shaped flooded valleys, of which approximately 554 km² are in Chile and 459 km² in Argentina.

Viedma Lake, approximately 50 miles (80 kilometers) long in southern Patagonia near the border between Chile and Argentina, is a major elongated trough lake formed from melting glacial ice. The Viedma Glacier measures 3 miles (5 kilometers) wide at its terminus at Lake Viedma.

Lago Argentino is a lake in the Patagonian province of Santa Cruz, Argentina. It is the biggest freshwater lake in Argentina, with a surface area of 1,466 km2 (566 sq mi) (maximum width: 20 mi (32 km)). It has an average depth of 150 m (492 ft), and a maximum depth of 500 m (1,640 ft).

The southern end of Argentina covers the left side of this image. Sediments can be seen by the coastline, particularly that of the province of Tierra del Fuego at the very bottom.

Further east, the Falkland Islands (or Islas Malvinas) can be observed amidst some patches of clouds. East Falkand (right) is cloud free, while West Falkland (left) is partially obscured. They are located 250 nautical miles (463 km; 288 mi) from the Argentine mainland.

The Strait of Magellan, visible at the bottom, comprises a navigable sea route immediately south of mainland South America and north of Tierra del Fuego. The eastern opening is a wide bay on the border of Chile and Argentina between Punta Dúngeness on the mainland and Cabo del Espíritu Santo on Tierra del Fuego. Here, the strait is mostly free of sediments, as opposed to the shoreline of Argentina to the east.

The waterway is the most important natural passage between the Pacific and the Atlantic oceans, but it is considered a difficult route to navigate because of the unpredictable winds and currents and the narrowness of the passage.

The strait is approximately 570 kilometres (310 nmi; 350 mi) long and about 2 kilometres (1.1 nmi; 1.2 mi) wide at its narrowest point (Carlos III Island, west of Cape Froward). The northwestern portion of the strait is connected with other sheltered waterways via the Smyth Channel. Southward from Cape Froward, the principal shipping route follows the Magdalena Channel.

Argentina - October 6th, 2009

Tierra del Fuego (Spanish for “Land of Fire”) is an archipelago 73,753 km2 (28,476 sq mi) off the southernmost tip of the South American mainland, across the Strait of Magellan. The southern point of the archipelago forms Cape Horn.

Tierra del Fuego is shared by Argentina and Chile. More precisely, 18.507,3 km2 belongs to Argentina (38,57% of the region’s total surface), 29.484,7 km2 belongs to Chile (61,43% of total surface).

The climate in this region is very inhospitable. It is a subpolar oceanic climate (Köppen climate classification Cfc) with short, cool summers and long, wet, moderate winters. The precipitation averages 3,000 mm (118 in) a year.

Temperatures in Ushuaia hardly surpass 9 °C (50 °F) in summers and average 0 °C (30 °F) in winters. Snowfall can occur in summer. The cold and wet summers help preserve the ancient glaciers.

The southernmost islands possess subantarctic climate typical of tundra that makes the growth of trees impossible. Some areas in the interior have a polar climate.
