Because of this natural ice dam, meltwater from the south raises water levels in Brazo Rico by as much as 30 meters above the level of the water in Lago Argentino. The great pressure of this water ultimately causes the ice tongue to rupture catastrophically in a great natural spectacle. The last rupture occurred in March , after this image was taken. The process repeats every four to five years as the glacier grows back towards the opposite shoreline.
The repeated ruptures have made the glacier and lake a major tourist attraction in the region. A more detailed astronaut view of the glacier tongue can be viewed here. The image was taken by the Expedition 30 crew. It has been cropped and enhanced to improve contrast, and lens artifacts have been removed.
The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet.

Related Articles Perito Moreno Glacier, what you need to know Every year the Perito Moreno glacier generate expectations when it seems ready to breakup. Some information on its characteristics and its history to help understand this phenomenon.
It is one of the few advancing glaciers in the world, and the only one in Patagonia. It advances approximately meters per year, generating another phenomenon of shoking beauty: the breaking of the dam it forms in the brazo Rico of Lago Argentino. Since its creation in , the detachment provides professional services. Los Glaciares is situated in the Southern Andes, which are shared with neighbouring Chile.
The World Heritage property is adjacent to the two national parks of Torres del Paine and Bernardo O'Higgins on the Chilean side, effectively forming a contiguous protected areas complex of impressive scale stretching across the border.
The integrity of the property is enhanced by its associated cultural and biodiversity values. There is a large altitudinal gradient from around m. Many place names go back to the Aonikenk, but petroglyphs and other artifacts are reminiscent of even earlier original inhabitants.
Against the backdrop of rugged, towering mountains the main ecosystems are subantarctic or Magellanic forests. Sometimes also referred to as cold Patagonian forests, they are dominated by various species of Southern Beech, some of which display dramatic colours in the autumn of the Southern hemisphere. After a transitional zone of woodland and scrub, the lower elevations further east mark the beginning of the vast semiarid Patagonian steppes.
Next to the peaks and glaciers there are highly specified subantarctic xerophytic cushion grasses. There is a rich bird fauna, including important breeding populations of the emblematic Andean Condor and Darwin's Rhea, sometimes called the "South American Ostrich" and locally known as Choique.
Despite its remoteness, Los Glaciares National Park is far from free of human impacts, such as domestic and feral livestock, forest fires and alien invasive species. Los Glaciares National Park attracts large numbers of national and international visitors requiring careful consideration and planning of tourism.
The property has an impressively long formal conservation history going back to Most of the territory of the Magallanes Peninsula, in which the Perito Moreno Glacier is located, is a Provincial Nature Reserve serving as a buffer zone of the property. The property has specialised administrative and technical staff and park rangers. There is also a fire brigade and support park rangers.
While the Superintendence and main administrative office operates in the small town of El Calafate, there are additional units distributed across the property. The Regional Technical Office Patagonia provides professional, scientific and technical assistance. It will require continuous review and updating in response to emerging demands. Since , Los Glaciares National Park established a local Advisory Council bringing together national, provincial and municipal entities, non-governmental organizations, the Chamber of Commerce, the Association of Tourist Guides and a Scout Group among others stakeholders.
While tourism is localized and many parts of the property can only be accessed by mountaineers and climbers there are seasonally crowded areas in the property requiring carful public use planning. The Public Use programme has been updated to fulfil the Restructuring Plan for the Moreno Glacier Sector, due to the increase in tourism and to the fact that it has the most appealing values for visitors.
This restructuring included road improvements, planning of visits through a new walkway system, services for visitors, such as restaurants and toilets, in order to improve the property protection and the quality of the visit.
Historically, overgrazing is among the biggest human impacts, in some areas to this day. Feral cattle remain in two uninhabited areas, Avellaneda Peninsula and Onelli Bay, and will eventually have to be removed.
The latter is part of a programme to control alien invasive species. Other noteworthy introduced species include the European Hare and trout species in the lakes and streams. Forest fires have likewise had a strong impact in the past leading to the degradation and even destruction of large areas within the property.
Removal of livestock and fire prevention will help restoration. The continuation and consolidation of the Research and Monitoring Programme are required, which include the project to conserve the Huemul Deer, one of the most remarkable species of the park.
