Watch | Spectacular ice show on Argentina glacier

The Patagonian glacier, known as the “White Giant” is one of Argentina's biggest attractions. The river of ice 18 miles (30 km) long ends in a sheer wall blocking Lago Argentino where large pieces tumble into the water from time to time. The glacier sheds ice roughly every four years and the last time big ice chunks fell off was 2012 but it could not be seen because it happened at dawn. Tourists and locals visited the site, located in the city El Calafate, in the Santa Cruz Province, in recent days, hoping to catch a glimpse of the rare spectacle.
