Baker Channel and Nearby Lakes in Patagonia – March 21st, 201046.4S 71.8W
The large lake stretching from Argentina (right) into Chile (left) in the upper portion of this image is known as Buenos Aires Lake in Argentina and General Carrera Lake in Chile. The lake has a surface of 1,850 km² of which 970 km² are in the Chilean Aisén Region, and 880 km² to the Argentine Santa Cruz Province, which makes it the biggest lake in Chile, and the fourth largest in Argentina.
Several other lakes, inlets and channels can be seen by the Andes Mountains in Chile. One of these is Baker Channel, also known as Calen Inlet, located in the Aisén Region (lower left quadrant). The Baker River discharges into Martinez Inlet, the northern part of this large estuary (appearing greenish tan with sediments).
It penetrates the mainland about 75 mi and opens into Tarn Bay at the south-east corner of the Gulf of Penas. Baker Channel also receives the waters of the O’Higgins/San Martín Lake through the Pascua River. The lake’s far-reaching fjord-like arms extend approximately from lat. 49° 11′ to 48° 22′ S. Its north-west arm is that which drains into the mentioned river.
