Chile and Argentina – November 16th, 2012

Several lakes can be seen by the Andes Mountains and Chile-Argentina border in this image of Patagonia. The northernmost is known as Lake General Carrera (Chilean side) or Lake Buenos Aires (Argentine side). It has a surface of 1,850 km² of which 970 km² are in Chile and 880 km² in Argentina, making it the biggest lake in Chile, and the fourth largest in Argentina. The lake is of glacial origin and drains to the Pacific Ocean on the west through the Baker River.

Visible to its south, also dark blue in color, is known as Cochrane Lake in Chile and Pueyrredón Lake in Argentina. The Argentine portion of the lake has a surface of 150 km2, while the portion in Chile covers 175 km2. It is a glacier fed lake.

Continuing southward, three light blue lakes can be seen: Lake O’Higgins/San Martín (the former name is used in Chile, the latter in Argentina), Viedma Lake and Argentino Lake. All three are glacial lakes, and their milky color is due to rock flour suspended in their waters.
