The Perito Moreno Glacier, located in Los Glaciares National Park, Argentina, is part of an ice field located in both Argentina and Chile that is the third largest reserve of fresh water in the world. It became a UNESCO World Heritage site in 1981.
The Glacier covers an area of 250 kilometres squared (97 miles squared) and spreads to a length of 30 kilometres (19 miles). It has a total height of 170 metres of ice, with around 74 metres protruding from the water’s surface.
Perito Moreno Glacier is named after Argentine’s Francisco Moreno, an explorer in the late 1800s and early 1900s, who was also known as ‘Perito Moreno’, the word ‘perito’ meaning ‘expert’ or ‘specialist’, which he officially became in 1902.
