The Perito Moreno Glacier has fall down on wednesday 9th of july 2008, after a few days of parcial break ups. Watch our on line videos here.
An explanation on the glacier rupture:
The Perito Moreno Glacier is one of only three Patagonian glaciers that are not retreating. Periodically the glacier advances over the L-shaped "Lago Argentino" ("Argentine Lake") forming a natural dam which separates the two halves of the lake when it reaches the opposite shore. With no escape route, the water-level on the Brazo Rico side of the lake can rise by up to 30 meters above the level of the main lake. The enormous pressure produced by this mass of waters finally breaks the ice barrier holding it back, in a spectacular rupture event. This dam/rupture cycle is not regular and it naturally recurs at any frequency between once a year to less than once a decade.

The Perito Moreno Glacier is one of the glaciers that makes up the “Los Glaciers” National Park with a dimension of 17.000 kilometres and is considered one of the most important drinkable water reserves in the world. Its’ front has a 5 km width and more than 60 sq mt of height over sea level. The last rupture took place in March 2004.
Since 1879 when the Glacier was first seen it had many names until 1899 when it received its proper name of Perito Moreno, in honor of the great argentine naturalist Francisco Pascasio Moreno. This exceptional argentine naturalist dedicated his life to exploration in the Patagonia, being his works of unspeakable relevance to the definite demarcation of the austral border between Chile and Argentina.
