In the south of Argentina is Patagonia's Los Glaciares National Park that contains the biggest glaciers in the world.
The Perito Moreno Glacier was created due to the merging of several large ice flows. Its tongue flows slowly into a southerly tributary of the Lago Argentino.
The most spectacular views of the glacier can be seen from an observation platform on the Magallanes Peninsula. It is like looking into another world, one that is full of primeval power and mysterious beauty.
Here amid the eternal ice is the largest supply of fresh water on Earth. Luckily, the glaciers of Patagonia have been spared from human interference with only possible climate change causing possible concern.
