Perito Moreno is a glacier located in Los Glaciares National Park, close to the southernmost tip of Argentina. The glacier is fed by the Southern Patagonian Icefield, a landform shared with Chile that has one of the largest reserves of fresh water in the world. It was named after Francisco Moreno, an explorer who helped including most parts of Patagonia in Argentina during their border disputes with Chile. This is one of only three glaciers located in the country that are still growing.
As such, the overwhelming pressure the glacier makes against the southern arm of the nearby Lake Argentina divides it, creating a dam.
When the water level rises, it eventually cracks portions of the glacier in a striking fashion, an event that has ocurred more often thoroughout the last few years. There are special tracks to get there, for those who are fond of hiking.
As an easier alternative, the spot can be reached through public transport, taking less than a couple of hours drive to Perito Moreno glacier from the nearest town El Calafate. Since it is easy to visit the Perito Moreno Glacier, lots of visitors go there every year to enjoy the magnificence of this place. There is no shortage of tour companies providing unique experiences in and around the place, from walking on the glacier itself to sailing in front of its majestic blue walls.
