The San Rafael Glacier is located in the Northern Patagonian Ice Field in Chile. It is one of the largest glaciers in the region and is known for its stunning blue ice formations. The glacier flows into the San Rafael Lagoon, creating a picturesque landscape that attracts visitors and researchers alike. The glacier is approximately 3,000 square kilometers in size and is a significant source of freshwater. It has been retreating over the years due to climate change, which raises concerns about its long-term stability and the impact on local ecosystems.
