It doesn't happen every year (last time was back in 2008) but this year Perito Moreno glacier near El Calafate, part of the Southern Patagonia Ice Field, has advanced far enough to join up with the shore on the Magallanes peninsula in Los Glaciares National Park.
When this happens a natural dam forms between the 'Brazo Rico' and 'Canal de los Tempanos' sections of the lake, the water level on the Brazo Rico side builds up, as does the pressure of the water on the ice, which eventually gives way in a spectacular 'dam bursting' rupture.
Exciting to be there when it happens - with the fabulous accessibility to Perito Moreno via the network of walkways on the peninsula opposite the glacier, there'll be at least one great photo of the blow-out when it goes I'm sure!
