Gulf of Corcovado

Chiloé Island and Gulf of Corcovado to the east

Gulf of Corcovado (Spanish: Golfo de Corcovado) is a large body of water separating the Chiloé Island from the mainland of Chile. Geologically it is a foreland basin that has been carved out by Quaternary glaciers. A large population of blue whales is found there, and it is under threat from salmon farming.^{[citation needed]}
