Situated in Los Glaciares National Park, a UNESCO World Heritage site, the breathtaking Perito Moreno Glacier is nearly 19 miles (30km) in length and spreads over an area of 97 square miles (250 sq km). The spectacular, blue-white ice formation is one of the only glaciers in the world that is growing, at a rate of seven feet (2m) per day. Enormous chunks of ice break off into the water with deafening crashes, creating icebergs and large waves. Also world renowned for its unique rupturing process, where high pressure causes the dam of ice to crack and shatter, sending icebergs downstream. Ruptures like this occur on average every four to five years, although sometimes as often as every other year. The closest town to this natural wonder is El Calafate in Argentina's Santa Cruz Province, which is about two hours' drive away.
