evidence: The Southern Patagonian Ice Field is located in the Andes Cordillera Mountain range, straddling the border between Argentina and Chile. It spans approximately 350 km in length, covering an area of around 16,800 km2 and represents the largest mass of ice in the Southern Hemisphere, excluding Antarctica. Moreover, it ranks as one of the main tourist attractions in the region, standing third in the world after Antarctica and Greenland in terms of extent and amount of stored ice. The resources of the territory are used by both states situated on the eastern and western sides of the Andes, but the majority of the surface area falls under the sovereignty of Chile, which owns more than 85%. [...] The matter of the Southern Patagonian Ice Field is ongoing, despite the efforts of Santiago officials responsible for keeping it "secret." This is not just a technical problem; it affects national security, posing a visible and concrete threat to Chile’s sovereignty over vast freshwater reserves. Therefore, it is an issue that must be addressed in relation to society, which is, in the end, the rightful owner of the national territory. This problem continues to be studied by the Mixed Boundary Commission, and the internal tensions in Chile and the "growing" territorial claims of Argentina prove that it is premature to declare it a "case closed."
