The Perito Moreno Glacier, located in Argentina's Los Glaciares National Park, is a massive ice formation that's 30 kilometres long and covers an area of 250 square kilometres. Named after explorer Francisco Moreno, this glacier is a popular tourist spot in Patagonia due to its impressive size and unique features. It's known for its occasional ruptures, where chunks of ice break off and create a spectacular natural show. The glacier has been retreating since 2020, possibly due to climate change, but it remains a must-see destination for visitors looking to witness the beauty of nature in action.
