Del Desierto Lake or Lake of the Desert (called Lago del Desierto in Argentina and Laguna del Desierto in Chile) is a natural lake located in the Lago Argentino Department, Santa Cruz Province, Argentina. Located near Monte Fitz Roy and the O'Higgins/San Martín Lake, Lago del Desierto was for many decades the subject of a territorial dispute between Argentina and Chile, escalating to a small firefight on 6 November 1965 when 40 to 90 members of the Argentine Gendarmerie fought against four Chilean Carabineros, of which a lieutenant was killed and a sergeant was injured. The dispute was resolved favourably for Argentina in 1994 by international arbitration.[1][2]
