February 15 is celebrated as National Glaciers Day in Argentina, recognizing the historical significance of the glaciers and their role in the ecosystem. This day commemorates the expedition of Francisco Pascasio Moreno, known as Perito Moreno, who was a key figure in Argentina's boundary dispute with Chile. He first arrived at Lago Argentino, where he named the lake and came close to the glacier that now bears his name, shedding light on the geographical history of the region.

The celebration serves not just as a historical reflection but also as a crucial reminder of the ongoing environmental challenges facing the glaciers due to climate change. These massive ice structures, which have formed over millennia and act as essential reserves of freshwater, are increasingly threatened by global warming, leading to their melting and fragmentation. Events marking this day aim to raise awareness about the importance of these glaciers, not only for their natural beauty but for their ecological role in regions like Patagonia.

As Argentina observes National Glaciers Day, it emphasizes the need for environmental stewardship and the promotion of actions aimed at mitigating climate change. The day brings together both historical remembrance and contemporary environmental advocacy, highlighting how past legacies can inform current conservation initiatives.
