Argentine Patagonia is home to one of UNESCO's heritage treasures, perhaps the most valuable of them all: Los Glaciares National Park. The park is an immense glaciological field, among the largest in the world outside the polar ice caps.
The best-known glacier in this area is undoubtedly Perito Moreno, whose front is visible in the image above.
The glaciers in this huge park are being affected by climate change, and in this comparison map I focused on two glacier fronts that have retreated the most in just 6 years.
