The Patagonian Icefield is one of the largest ice fields outside of Antarctica and Greenland, located in the southern Andes of South America. It spans both Chile and Argentina, covering approximately 13,000 square kilometers. This vast expanse of ice feeds numerous glaciers, including the famous Perito Moreno Glacier, which is known for its dramatic calving events. The icefield is a crucial part of the region's ecosystem, influencing local climate and hydrology. It serves as a vital water source for rivers and lakes in the area, supporting diverse wildlife and vegetation. The Southern Patagonian Icefield is also a popular destination for tourists and researchers interested in glaciology and climate change.
