The largest glacier in South America and this one is growing. The end of the glacier is around 5km wide and curves round at the edges seen here. The width seen here is probably around 1 to 1.5km. It is also very fast moving at around 1.8 metres/day so chunk of ice fall off fairly frequently and there is a continual noise.
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 the height of the dammed water finally breaks the ice barrier holding it back, in a spectacular rupture event. This dam/rupture cycle is not regular and it recurs naturally at any frequency between once a year to less than once a decade.
The glacier is in Argentinian Patagonia.
