The Perito Moreno glacier, also called the ‘White Giant’, is located near the city of El Calafate in the Argentine province of Santa Cruz, and comes under the Los Glaciares National Park — a UNESCO World Heritage Site.
It was formed during the last Ice Age, which occurred approximately 18,000 years ago. Estimates suggest that the glacier is 30 km long, and has a towering height of 60 m above the water level. Due to its enormous size, it is a major source of freshwater for Argentina.
