The Perito Moreno Glacier (Spanish: Glaciar Perito Moreno) is one of the best-known and most spectacular glaciers on Earth. It is situated in Los Glaciares National Park in the Argentine province of Santa Cruz, in south-western Patagonia. The glacier stretches for around 30 kilometres and is 5 kilometres wide. The impressive ice front rises, on average, 55 to 75 metres above the surface of Lago Argentino. Underwater, the ice extends a further 100 metres or so into the depths. Unlike most glaciers worldwide, which are shrinking due to global warming, the Perito Moreno Glacier is in a relatively stable equilibrium. It advances by up to 2 metres every day. As a result of this continuous movement, chunks of ice as tall as houses regularly break off from the front. This phenomenon is accompanied by a thunderous crash and a deep rumble that can be heard for kilometres. As it advances, the glacier periodically blocks a side arm of Lago Argentino (Brazo Rico). The dammed-up water builds up enormous pressure until the barrier finally collapses in a spectacular process lasting several days. – Argentina – 1973
