The story behind it
This lake lies in the far south of South America, at the edge of the Andes. It is about 130 km long and very deep: in one place the water goes down 586 metres, so the bottom lies about 350 metres below sea level! About 970 km² of the lake belong to Chile and about 880 km² to Argentina. It is the largest lake in Chile and the fourth-largest in Argentina. The Aonikenk people called it Chelenko, which means 'stormy waters'. On the north-western shore, near Puerto Río Tranquilo, waves have carved the Marble Caves out of the rock over the last 6 200 years. The lake has its own sunny weather, and anglers come to catch trout and salmon. Its water flows out through the Baker River to the Pacific Ocean.
