Brüggen Glacier
Brüggen Glacier, also known as Pío XI Glacier, is the largest western outflow from the Southern Patagonian Ice Field in southern Chile. It holds the distinction of being the longest glacier in the Southern Hemisphere outside of Antarctica, with a length of approximately 66 km. Notably, unlike many glaciers globally, Brüggen Glacier experienced significant advancement between 1945 and 1976, surging several kilometers and altering the local fjord landscape.

About Brüggen Glacier
Brüggen Glacier, also recognized as Pío XI Glacier, is a prominent glacial feature located in southern Chile. It stands as the largest western outflow from the expansive Southern Patagonian Ice Field. With an approximate length of 66 km (41 mi), it holds the significant distinction of being the longest glacier in the Southern Hemisphere beyond the Antarctic continent. The glacier carries the name of German geologist Juan Brüggen Messtorff.
Glacial Dynamics and Impact
In contrast to the global trend of retreating glaciers, Brüggen Glacier exhibited a remarkable period of advancement from 1945 to 1976. During this time, it surged approximately 5 km (3.1 mi) across Eyre Fjord. This advance led to the glacier reaching the western shore of the fjord by 1962, effectively cutting off Lake Greve from the sea. The glacier continued to extend both northward and southward within the fjord, adding nearly 60 square kilometers of ice and reaching a position close to its current extent before stabilizing.
Accessibility and Observation
Brüggen Glacier is a destination for expedition cruise ships, which navigate up Eyre Fjord from the sea to reach the Pío XI terminus. This accessibility allows for direct observation of the glacier's impressive ice formations and its dynamic environment.

Jorge Montt Glacier
Jorge Montt Glacier is a significant tidewater glacier located in Chile's Aisén Region, within Bernardo O'Higgins National Park. It is notable for its rapid thinning and substantial retreat, which has been linked to both climate warming and the unique bathymetry of its fjord. The glacier plays a role in the local environment, calving icebergs into the Baker Channel.
