Southern Patagonian Ice Field dispute

The Southern Patagonian ice field dispute is a border dispute between Argentina and Chile over the delineation of the boundary line between the two countries on the Southern Patagonian Ice Field, a large expanse of glaciers located in the Patagonian Andes, which is the largest non-polar continental ice field with land access. It is called continental ice in Argentina and southern ice field in Chile, to differentiate it from the northern ice field.
